Typical Applications

• Audio — Designed for use in audio products and circuits where low leakage and defined ripple performance support stable audio power and signal coupling requirements.

Unique Advantages

• Low leakage minimizes bias drift: Specified leakage current of 16.5 µA supports applications sensitive to leakage‑related performance changes.
• Defined ripple capability across frequencies: Rated ripple currents of 490 mA (120 Hz) and 735 mA (10 kHz) provide predictable AC handling for power filtering in audio circuits.
• Compact radial can: Small φ10 × 20 mm can with 5 mm lead spacing allows dense through‑hole layouts while maintaining serviceable capacitance.
• Extended endurance at elevated temperature: 2000 hours at 85°C gives a measurable lifetime metric for thermal stress planning.
• Wide operating range: −40°C to +85°C operating temperature accommodates typical environmental conditions for consumer and professional audio equipment.
• RoHS compliant packaging options: Bulk or bag packing choices and RoHS compliance simplify procurement and assembly processes.
