• Voltage & Loss Rated for 200 V with tanδ (loss tangent) of 0.15 measured at 20°C, 120 Hz.
• Ripple Current Capability Low‑frequency ripple current: 1.35 A at 120 Hz; high‑frequency ripple current: 2.025 A at 50 kHz.
• Leakage & Reliability Leakage current of 830 µA (measured per product data) and endurance rating of 3000 hours at 105°C under DC bias plus rated ripple current.
• Environmental & Packaging RoHS‑compliant construction and supplied in tray packing suitable for production handling.
• Temperature Range & Size Operating temperature −40°C to 105°C; physical size φ22 × 30 mm (L: 3.0 cm × D: 2.2 cm).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling where a 200 V, 390 µF capacitor is required for energy storage and ripple reduction.
• Power supply front‑end — DC link and bulk capacitors in power conversion stages that benefit from high ripple endurance at elevated temperature.
• Industrial electronics — General‑purpose use in systems that require robust operation from −40°C to 105°C and tray packaging for production environments.

Unique Advantages

• Long high‑temperature endurance: Rated for 3000 hours at 105°C with DC bias plus rated ripple current, supporting long service life in hot environments.
• High ripple handling: Defined ripple currents of 1.35 A (120 Hz) and 2.025 A (50 kHz) enable effective AC ripple absorption across common power frequencies.
• Compact snap‑in form factor: φ22 × 30 mm can with snap‑in terminals provides a space‑efficient solution for robust board retention.
• Controlled dielectric loss: tanδ 0.15 at 200 V (20°C, 120 Hz) supports predictable AC performance for designers tuning filter characteristics.
• Low leakage: Specified leakage current of 830 µA aids in predictable standby behavior and power budgeting.
• Production‑ready packaging: Tray packing facilitates handling and integration into manufacturing workflows.
