Chongdiantou's December 2023 survey of surface mount Y capacitors placed STE alongside TRX and JingQin in a discussion of thinner, more densely assembled fast chargers. The STE section focused on compact ceramic safety capacitors, surface mount production and potential use across power conversion applications.

The engineering question behind the report remains practical: how can a designer allocate less mechanical space to the EMI filter while retaining the required electrical and insulation performance? Component packaging is part of that decision, together with the PCB layout, circuit connection and manufacturing process.

## STE's contribution to the reported product landscape

The article described STE's SMD ceramic safety capacitor construction and reel packaging, including support for automated surface mount assembly. It also reported flame-retardant encapsulation and environmental characteristics. Those statements describe the product presentation at the time; an actual design should use the selected part's drawing, process requirements and approval documentation.

The article named applications including switching power supplies, adapters, lighting, communications equipment and meters. These examples identify the markets considered in the original coverage. They do not establish that every value or package is qualified for every listed use.

STE's contribution to the reported product landscape

| Topic in the STE coverage | What a design team needs to establish |
| --- | --- |
| Compact surface mount construction | Body dimensions, terminal geometry, land pattern and surrounding clearance |
| Ceramic safety capacitor function | Required safety class and the circuit connection it must serve |
| Reel packaging and automated assembly | Compatible soldering profile, placement process and board support |
| Environmental performance | Exact test conditions and limits for the selected part |

## TRX: Y1, Y2 and high-voltage ceramic products

The historical profile describes Sichuan TRX as established in 2014 in Mianyang, with RMB 100 million registered capital and a predecessor business founded in Shenzhen in 2004. It identifies SMD TRX and leaded TY capacitor brands, ceramic-material development and applications in switching supplies, LED lighting, UPS equipment, electronic ballasts, household-appliance controls and security equipment.

The source reports ISO 9001, ISO 14001, ISO 45001 and QC 08000 management-system certifications, together with CQC, UL/CUL, VDE, ENEC and KC product approvals. These references describe reported historical coverage; a product family's exact approval scope remains separate from the company's management systems.

TRX's molded SMD-Y1 construction places the ceramic element horizontally and brings out two terminals for surface mounting. The article describes an L-shaped terminal form, reduced body-height and dimensional variation, and compatibility with reflow and wave soldering. Its standard 7854 range is reported as 2–2200 pF, while high-capacitance 10596 covers 680–10000 pF. The example body measures 10.5 × 9.6 × 2.58 mm. The narrative pairs “102K” with 10000 pF/Y5V/±20%, an inconsistent combination; the translated product table is retained for individual values rather than treating that sentence as a valid complete part specification.

The SMD-Y2 discussion gives 2–2200 pF for 4335 and 680–4700 pF for 6056. A cited iQOO 120 W GaN charger teardown reports two TBY2101KB parts and two TBY2331KB parts. The source reports a 26% reduction in charger volume, 35 g lower weight and 1.31 W/cm³ power density for that equipment comparison. These finished-product figures do not isolate the contribution of the capacitors.

TRX also presents a high-voltage ceramic family with a 4.3 × 3.5 × 2.2 mm body, 47–2200 pF options and reported voltage choices from 1 to 3 kV. The source describes these as compact alternatives to leaded high-voltage ceramic parts; their voltage class does not itself make them Y safety capacitors. Related reading covers TRX's high-capacitance Y1 introduction and the Y2/high-voltage ceramic launch.

## JingQin: four internal arrangements

The JingQin profile dates the business to 2013, with research in Shenzhen and a Huizhou factory entering production in 2019. It describes surface-mount varistors, thermistors and X/Y safety capacitors, with patents for multi-element capacitor and thermistor arrangements. Reported management systems include ISO 9001:2015, ISO 14001:2015 and IATF 16949. The source also lists product safety and environmental-compliance claims, without establishing their current scope for each component.

Its laboratory description covers surge-current and combination-wave testing, destructive voltage testing, pulse tests, 85°C/85% RH exposure, high-temperature endurance, thermal shock, salt spray and vibration. Stated applications include LED protection, industrial and switching supplies, 5G infrastructure, consumer electronics, appliances and automotive electronics.

The product section distinguishes four Y1 arrangements. A single-element 2822 version uses gull-wing terminals and a reported 7 × 5.6 × 2.4 mm body. A single-element 4524 uses inward-bent terminals and measures 11.4 × 6 × 2.4 mm. Both are described with 10–2200 pF and a 500 V rating. A two-element parallel 4524 arrangement increases available capacitance, with examples labeled Y5P-102K, Y5U-222M, Y5U-332M and Y5V-472M. A two-element series 4524 arrangement is presented as a way to combine two Y functions in one package, with a reported 10–2200 pF range and 500 V rating. Its suitability still depends on the required circuit and insulation arrangement.

The source describes UL94 V-0 encapsulation, tape-and-reel supply, automated assembly and high-temperature/humidity performance across this product presentation. Its cost, reliability and space-saving comparisons are supplier claims, not independently measured results in the article. Individual dimensions and model entries are preserved in the translated source tables.

## Company and exhibition context

The STE profile identifies the Shantou bonded-zone company founded in 2012 and reports a 75,000 m² development and production campus. It names ceramic and film capacitors, varistors and thermistors, provincial and municipal engineering-center recognitions, UL-recognized laboratories, and company management and product-safety certifications. These are historical company statements; they do not extend every certification to every SMD option.

The original exhibition invitations concerned the March 20–22, 2024 Asia Charging Expo: TRX at C35/C36/C47/C48, JingQin at C67 and STE at B62. They are historical notices. The original's further-reading section also linked to previews of capacitor, wireless-charging, charging-solution, semiconductor and specialist-enterprise exhibitors.

## Using the historical report today

The letter Y identifies a safety capacitor category; it is not an abbreviation for a claimed level of electromagnetic compatibility. A Y capacitor can provide a path for high-frequency common-mode current, subject to the equipment's insulation and permitted-current requirements. The required class must be selected for the actual connection.

STE's present package-specific information is available through the SMD-X1Y1 and SMC-X1Y2 product pages. These references allow a reader to move from historical reporting to a particular component specification. [SMD-X1Y1](https://www.songtian-ste.com/en/products/ceramic-capacitors/smd-x1y1/) [SMC-X1Y2](https://www.songtian-ste.com/en/products/ceramic-capacitors/smc-x1y2/)

The original article also announced STE's participation in the spring 2024 Asia Charging Expo. That invitation belongs to the article's publication period and is retained in the Chinese source as historical context.
