### Selection guide

Start from the insulation diagram of the equipment and the maximum continuous AC/DC voltage. Then check Y-capacitor leakage, effective capacitance, impulse duty, AEC-Q200 and approval scope, humidity and cycling data, dimensions, marking and assembly process for one part number.

1. **Classify the insulation and circuit position**
   Identify line-to-earth, primary-to-secondary or across-the-line duty from the equipment standard. Confirm that Y2 basic or supplementary insulation is sufficient; use Y1 where reinforced insulation is required.
2. **Define continuous AC, DC and impulse voltage**
   Use the approval voltage code of the selected part. The 1,500 VDC approval scope, the 2.6 kVAC proof test and the impulse duty are different quantities; none replaces another. Impulse data on request.
3. **Set capacitance from EMI and leakage together**
   Calculate common-mode attenuation and I = 2πfCV at maximum voltage, frequency and tolerance for every Y capacitor. Use temperature, bias, frequency and aging curves so that nominal capacitance is not mistaken for effective capacitance.
4. **Request automotive and safety documentation**
   Request the AEC-Q200 revision and report, qualified part numbers, grade, site, stress groups, sample sizes, results and PPAP/change control, together with the current CQC, VDE, CB and UL scope for the same marking and construction.
5. **Confirm body, leads, packing and process**
   Check the capacitance and approval voltage codes, drawing, blue coating and marking, lead form and length, taping, soldering, cleaning, storage and post-process acceptance of the selected part number.

Each certificate covers the types and ratings listed on it.

### Design notes

#### Y2 is not reinforced insulation

Select from the insulation diagram of the equipment, not from the capacitor marking alone. Where the circuit requires reinforced insulation, use a Y1 capacitor and verify PCB and enclosure creepage, clearance and abnormal-condition design.

#### Calculate leakage at maximum conditions

Use maximum capacitance, tolerance, line frequency and voltage for each Y capacitor and total the complete network. Keep margin for the temperature, bias and aging behavior of the dielectric and for the touch-current limits of the equipment.

#### Keep proof, impulse and working voltage apart

X1/Y2 AC ratings, the 1,500 VDC Annex H scope, the 2.6 kVAC proof test and the impulse duty are different quantities. Check each value and its test method for the selected part and circuit position.

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

CQC, VDE, CB and UL approvals confirm the safety classification of the component. They do not establish automotive stress qualification, PPAP, site traceability or mission-profile life. Both must apply to the same part number.

#### Control the radial assembly process

Observe the wave-soldering profile and the 360 °C hand-rework limit. Keep heat and bending stress away from the coating. Review cleaning, coating, storage, shelf-life and vibration data before production.
