Design from ripple spectrum and hot spot
DC-link voltage alone does not select the part. Sum harmonic currents using part-level ESR, include terminal current and cooling, and verify the measured hot spot against the life model for the part.

Selection guide
Start with the converter mission profile, not only bus voltage and capacitance. Coordinate steady-state and transient voltage, stored energy, ripple spectrum, ESR/ESL, hot-spot temperature, cooling, humidity, altitude, lifetime, discharge safety and two- or four-pin mechanics.
Define bus, ripple and mission profile
Define nominal and maximum DC bus voltage, switching and low-frequency ripple spectra, regenerative or fault overvoltage, precharge and discharge behavior, ambient temperature and cooling, altitude, humidity, vibration and the lifetime histogram.
Select a voltage and capacitance combination
Select from the voltage/capacitance table in the datasheet and observe the maximum capacitance at each voltage. The 2–180 µF series range does not apply at every voltage.
Calculate current, loss and hot spot
Calculate harmonic Irms and energy E = ½CV², and check them against the part's ESR versus frequency and temperature, ESL and resonance, Irms, ripple-voltage, terminal-current, Rth, hot-spot and self-heating limits (on request).
Apply voltage derating and a life model
Apply the voltage derating above +85 °C and a life model based on voltage, hot spot, ripple, humidity and altitude. THB, loaded and ripple life, FIT rate and end-of-life criteria for the mission profile on request.
Specify terminals, safety and assembly
Specify W/H/T, pitch, two- or four-pin layout, lead diameter and length, packing and marking for the part number. Define discharge and touch protection, creepage and clearance, mechanical support, wave soldering, cleaning, coating and vibration acceptance.
Approvals & reliability
Reliability tests
Initial dissipation factor, insulation resistance and voltage proof are specified, together with voltage derating and dimension tables. ESR, ESL, ripple-current, thermal, THB and lifetime data on request.
| Test | Condition | Acceptance |
|---|---|---|
| Initial characteristics | tan δ ≤0.2% at 1 kHz / 1 Vrms / 20 °C; IR ≥10 GΩ at 100 VDC / 60 s / 20 °C | Measurement details on request |
| Voltage proof, terminal to terminal | 1.5 × UR, 10 s | Ramp, trip current and post-test ΔC, tan δ, IR and visual criteria on request |
Design notes
Account for stored energy and the discharge path
Use E = ½CV² for every operating and fault condition. Define precharge, bleeder or discharge, residual voltage, service isolation and short-circuit protection outside the capacitor.
Maximum capacitance depends on voltage
The series reaches 180 µF only at 500 V; at 1,200 V the maximum is 25 µF. Select from the voltage/capacitance table.
Treat humidity and life as selection parameters
For solar, wind, storage and industrial service, request THB data with applied bias, a voltage, hot-spot and ripple life model, and post-test capacitance, ESR/loss, IR and visual limits.
Minimize loop inductance
Two- and four-pin versions can differ in ESL and current sharing. Use the terminal drawing and impedance data for the part; keep busbar and PCB commutation loops short and symmetric.
Support the case and control solder heat
Large cases need mechanical restraint and vibration validation. Do not reflow-solder; use the wave- or hand-soldering profile specified for the part, and validate cleaning, coating, lead stress and thermal cycling.
