### Selection guide

Start with the pulse waveform and failure behavior: foil electrodes can support high peak current but are not self-healing like metallized film. Then check voltage, capacitance, dV/dt, repetitive and RMS current, frequency, hot-spot rise, lifetime and dimensions.

1. **Define the complete pulse waveform**
   Specify DC bias, peak voltage, rise and fall time, dV/dt, pulse width, repetition rate, ringing, polarity reversal, start-up and abnormal transients. Separate one-time ignition or surge events from continuous repetitive duty.
2. **Select voltage and capacitance**
   The series covers 1–47 nF at 400/630/1,000 VDC with 7.5/10/15 mm lead spacing. For other voltages, values or 5 mm lead spacing, request the specification.
3. **Calculate current, energy and frequency stress**
   Use Ipk = C·dV/dt and the actual waveform to calculate peak current, repetitive energy and RMS current, and check them against the dV/dt, K0, Ipk, Irms, ESR, ESL, impedance and resonance limits.
4. **Check temperature rise and lifetime**
   Calculate dielectric and connection losses and hot-spot rise at the actual spectrum and enclosure ambient. The climatic category is 40/100/21 while operation extends to +105 °C: voltage, frequency and temperature derating, and pulse, dry-heat and humidity life data, on request.
5. **Confirm construction and assembly**
   Match the part number to electrode construction, voltage, capacitance, tolerance, W/H/T, lead spacing, lead form, packing and soldering profile. Do not use reflow soldering; validate lead forming and vibration.

### Design notes

#### Foil electrodes are not self-healing

Metallized film normally clears local faults; aluminum-foil electrodes do not. Do not rely on self-healing or fail-open behavior; electrode-construction and failure-mode data on request.

#### Usable frequency range

Voltage, capacitance, ESR, ESL, resonance, RMS current and cooling determine the usable frequency range. Use voltage and current versus frequency curves for the selected part and validate hot-spot rise on the final board.

#### Calculate pulse current from the actual waveform

For an ideal capacitor, I = C·dV/dt. Include overshoot, ringing and repetition, then apply the dV/dt, K0, peak and RMS current, energy and temperature limits of the selected part.

#### Define the ballast mission profile

Record ignition transient, steady resonant current, lamp-open and end-of-life modes, switching frequency, enclosure temperature and service hours, and validate the selected part number against them.

#### Ratings outside the standard range

For other voltages, values below 1 nF or above 47 nF, or 5 mm lead spacing, request the part specification, drawing and qualification report. Do not extrapolate from a neighboring value.

#### Control assembly and lead stress

Apply the PP/PE soldering limits to the actual construction and do not use reflow soldering. Keep lead-forming stress away from the epoxy interface, and validate cleaning, coating, vibration and thermal cycling.
