### Selection guide

Start with the AC or DC waveform and the voltage stress that calls for an internal-series construction. Then check capacitance, dV/dt, peak and RMS current, frequency, hot-spot rise, fault response, lifetime and dimensions.

1. **Define the waveform and mission profile**
   Specify DC bias, AC fundamental, peak voltage, rise and fall time, dV/dt, repetition rate, RMS current, harmonics, start-up or ignition and abnormal transients, together with ambient temperature, cooling and service hours.
2. **Select voltage and capacitance**
   The series covers 400/500/700/900 VAC, paired with 1,000/1,200/1,600/2,000 VDC, at 1–100 nF. Keep the AC or DC rating basis, and request the specification for any other rating.
3. **Calculate pulse, resonance and section stress**
   Use Ipk = C·dV/dt and the measured spectrum to calculate peak, repetitive and RMS current, and check them against the dV/dt, K0, ESR, ESL, impedance, thermal-resistance, frequency-derating and internal section-voltage data (on request).
4. **Check construction, fault response and lifetime**
   Check the number of series sections, voltage sharing, self-healing behavior and fault response of the selected part number, together with its AC and pulse endurance and humidity test data.
5. **Confirm dimensions and assembly**
   Match voltage, capacitance, tolerance, W/H/T, lead spacing, lead form, packing and soldering profile to the part number. Do not use reflow soldering; validate lead forming and vibration.

### Design notes

#### Keep AC and DC ratings separate

Each AC rating is paired with a DC rating, without waveform, frequency or lifetime correlation. Use the rating that matches the application; do not convert by a simple peak or RMS ratio.

#### Internal series construction

Series sections can increase voltage capability. Selection still depends on the section count, voltage sharing, margins, self-healing and overload behavior of the selected part.

#### Calculate pulse and resonant current from the measured spectrum

Measure the actual spectrum, including ignition and abnormal modes. Combine I = C·dV/dt with RMS current, ESR and thermal resistance to verify hot-spot rise and resonance margin.

#### Ratings outside the standard range

For values above 100 nF, 27.5 mm lead spacing or other voltage ratings, request the part specification, construction drawing and qualification report. Do not extrapolate.

#### Control assembly and mechanical support

Apply the PP/PE soldering limits to the actual construction and do not use reflow soldering. Keep lead-forming stress away from the epoxy seal, and validate cleaning, coating, vibration and thermal cycling, especially for the 26 mm body.
