### Selection guide

Confirm that Class Y2 is permitted in the actual insulation architecture and calculate the total leakage current. Then specify one G-suffix part number whose AEC-Q200 report, safety approvals, voltage, capacitance, body, suffix and lead-form meaning, current and thermal limits, packing and process all match the application.

1. **Confirm the Y2 insulation position**
   Use line to protective earth or another bypass position only where Y2 basic or supplementary insulation is permitted. Use Y1 for reinforced insulation or the higher impulse requirement.
2. **Calculate the complete leakage budget**
   Use maximum capacitance including tolerance, line voltage and frequency, then sum every Y capacitor and other leakage path against the normal and single-fault equipment limits.
3. **Confirm automotive and safety scope**
   Request the AEC-Q200 Rev E report for the selected part number, with qualified part numbers, grade, site, lots, results and requalification record, and the current safety certificates for the same construction and marking.
4. **Confirm the part number and mission profile**
   Obtain the drawing and code definition for part numbers with the suffix −02 or other lead codes, and for values above the maximum per pitch. Then coordinate AC, impulse, humidity, vibration, current, hot spot and life.
5. **Confirm mechanics, process and traceability**
   Confirm the G suffix, drawing, marking, body and lead geometry, packing and PP/PE construction with STE. Validate spacing, soldering, cleaning and coating, storage, screening and traceability.

### Approvals & reliability

#### Approvals & qualifications

AEC-Q200 is a stress-test qualification for automotive components; IEC 60384-14 approvals cover the Y2 safety function separately. Approval and AEC-Q200 coverage of individual G-suffix part numbers, including suffix −02 versions, on request.

| Agency | Standard | Certificate | Scope |
| --- | --- | --- | --- |
| UL UL / cUL | UL 60384-14 | E208107 | MPY Y2, 0.001–1.2 µF, 250–350 VAC |
| IECEE CB IECEE CB | IEC 60384-14:2013 + AMD1:2016 | DE1-67208 | MPY Y2, test report 300758-TL3-1 |

Each certificate covers the types and ratings listed on it.

#### Reliability tests

Initial electrical limits, AEC-Q200 Rev E qualification, temperature cycling (1,000 cycles, −55 °C to +110 °C), an impulse test sequence and a self-ignition test are specified.

| Test | Condition | Acceptance |
| --- | --- | --- |
| Temperature cycling | 1,000 cycles, −55 °C to +110 °C | Dwell time, sample size and post-test ΔC, tan δ, IR, voltage-proof and visual limits on request |
| Initial characteristics and voltage proof | tan δ ≤0.15%; IR ≥15 GΩ or RC ≥5,000 s; voltage proof terminal to terminal and terminals to case | Measurement conditions and voltage-proof method on request |

### Design notes

#### Y2 does not provide reinforced insulation

Use line to protective earth or another bypass position only where Y2 basic or supplementary insulation is permitted. Reinforced barriers require Y1.

#### Leakage current sets the usable capacitance

Sum all Y capacitors and leakage paths at maximum capacitance, voltage and frequency against the normal and single-fault equipment limit.

#### AEC-Q200 and safety approval are separate

Map the AEC-Q200 report and the current safety certificates to the same G-suffix construction and manufacturing site.

#### Confirm impulse data before design-in

Obtain the impulse test voltage, circuit and the complete impulse and self-ignition report from STE before setting an application limit.

#### Control spacing, assembly and failure path

Validate creepage and clearance, protective earth, fusing, soldering, cleaning and coating, vibration and open- and short-circuit behavior. Do not reflow-solder.
