• High‑temperature operation: Rated operating temperature range of −25°C to +105°C with endurance specified for 3,000 hours at 105°C.
• Charge–discharge durability: Snap‑in type designed for high‑speed charge–discharge behavior and suitable for regenerative voltage and frequent cycling conditions.
• Package & mounting: Radial, can‑style snap‑in terminal for secure PCB retention; nominal size L: 3 × D: 2.5 cm and maximum seated height 1.181 inch.
• Leakage and dissipation: Leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ limits provided for rated voltages (350 V tan δ ≤ 0.15).
• Regulatory compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Motor drives & inverters: Energy buffering and DC link smoothing in AC servomotor and inverter systems where regenerative currents and voltage swings occur.
• Regenerative circuits: High‑speed charge–discharge capability makes this capacitor suitable for high‑frequency regenerative voltage handling.
• Voltage‑doubler/rectifier stages: Use in rectifier circuits and voltage‑doubler arrangements that require robust, polarized high‑voltage capacitance.
• Industrial power supplies: Filtering and energy storage in equipment operating in environments with voltage fluctuation and elevated temperatures.

Unique Advantages

• Designed for pulse‑intensive circuits: High‑speed charge–discharge construction tailored for regenerative and cyclic applications reduces stress on surrounding components.
• High operating temperature rating: Continuous operation to 105°C and 3,000‑hour endurance at that temperature provide predictable lifetime performance in hot environments.
• Dual‑frequency ripple capability: Rated ripple current at both 120 Hz and 50 kHz supports performance across low and high switching frequencies.
• Robust leakage and dissipation characteristics: Defined leakage current formula and tan δ limits allow engineering teams to size and model system losses accurately.
• Secure snap‑in mounting: Radial snap‑in can simplifies PCB retention and mechanical stability in power assemblies.
• RoHS compliant: Meets applicable RoHS directives for restricted substances.
