• Ripple Current Capability: 700 mA at 120 Hz and 805 mA at 10 kHz, supporting continuous ripple loads at both low and high frequencies.
• Safety Features: Designed with an operating pressure relief vent and defined safety performance tests for abnormal overvoltage conditions.
• Leakage and Dissipation: Leakage current specified as I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ ≤ 0.20 at 120 Hz, 20°C.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Size: Size dimension L: 2.5 × D: 3.5 cm in a radial, can‑snap‑in form factor.

Typical Applications

• General‑purpose power filtering: Bulk smoothing and decoupling in power supplies and electronic equipment that require reliable high‑voltage capacitance.
• Equipment exposed to voltage fluctuations: Systems operating in environments with unstable supply voltages where enhanced abnormal‑voltage tolerance is needed.
• High‑temperature operation: Applications requiring sustained ripple endurance at elevated temperatures up to 105°C.

Unique Advantages

• Long ripple endurance at 105°C: Specified to withstand 2000 hours of rated ripple at 105°C, supporting reliable operation under continuous stress.
• High voltage capability: 400 V rating (with series availability at 200 V and 420 V) provides flexibility for higher‑voltage designs.
• Clear safety characterization: Pressure relief vent and defined limited DC current test conditions for 400 V, 100 ≤ C < 220 μF category (4 A test current at 500 VDC and 600 VDC) enhance predictable behavior under abnormal conditions.
• Quantified leakage and dissipation specs: Leakage current formula (I ≤ 3√CV) and tan δ limit (0.20 max) enable predictable loss and standby current planning.
• RoHS compliance: Meets 2011/65/EU and (EU)2015/863 requirements for restricted substances.
