Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a 200 V rated voltage and tolerance of ±20% (–20% to +20%).
• Package and Mounting — Radial, can‑style snap‑in terminal package for secure snap‑in mounting.
• Temperature Range — Operating temperature range from –40°C to +85°C (category temperature range specified for 16 to 250 V in the series data).
• Ripple‑Current Endurance — Designed to withstand 3000 hours application of rated ripple current at 85°C per series endurance specification.
• Ripple Current Ratings — Specified ripple current: 2.81 A at 120 Hz and 4.215 A at 50 kHz for this part.
• Stability and Endurance Parameters — Series endurance criteria: capacitance change within ±20% after endurance, tan δ up to 200% of initial specified value, and leakage current less than or equal to initial specified value following the endurance test.
• Leakage Current Specification — Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes at 20°C (C in µF, V in V) as given in the series datasheet.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Size: L: 4.5 × D: 2.2 cm; height seated maximum specified as 1.772 inch in product data.

Typical Applications

• General Purpose Power Systems — Provides bulk capacitance in general‑purpose designs requiring polarized aluminum electrolytic capacitors at 200 V.
• Industrial Electronics — Snap‑in radial can construction supports applications where a robust, board‑mountable polarized capacitor is required within the –40°C to +85°C operating range.
• Equipment Requiring Ripple‑Current Endurance — The 3000 hour rated ripple‑current endurance at 85°C addresses use cases that demand sustained ripple handling over extended periods.

Unique Advantages

• Proven Ripple Endurance: Withstands 3000 hours of rated ripple current at 85°C, offering predictable long‑term behavior under ripple stress.
• High Voltage Capability: 200 V rating supports higher‑voltage general‑purpose designs where larger voltage margins are required.
• Clear Electrical Limits: Specified ripple‑current values at 120 Hz and 50 kHz (2.81 A and 4.215 A respectively) enable straightforward thermal and reliability calculations.
• Measurable Leakage Standard: Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes at 20°C provides a verifiable leakage performance metric.
• RoHS Compliant: Conforms to applicable RoHS directive requirements for restricted substances.
• Snap‑In Mechanical Retention: Radial snap‑in terminal package simplifies installation where secure snap‑in mounting is preferred.
