Built for audio designers, this capacitor combines a snap-in mounting package with a compact 25 mm diameter × 20 mm length form factor, RoHS compliance, and specified ripple and endurance characteristics suitable for demanding audio power and decoupling stages.

Key Features

• Capacitance — 820 µF nominal capacitance with a tolerance of ±20%, specified for measurement conditions at 120 Hz and 20 °C.
• Rated Voltage & Ripple — 80 V rated voltage with a specified ripple current of 1.65 A at 120 Hz, providing headroom for higher-voltage audio supply rails.
• Low Loss (tan δ) — tan δ = 0.25, helping to minimize loss and preserve audio signal integrity in high-tone-quality equipment.
• Package & Mounting — Snap-in terminal, radial can package for robust board mounting in power supply and large-capacitor placements; physical size is 25 mm Ø × 20 mm L (approx. 2.5 cm × 2.0 cm).
• Temperature & Endurance — Operating range −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C, supporting reliable operation under elevated temperature conditions.
• Polarized — Polarized electrolytic design intended for DC power and filtering applications in audio circuits.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting modern environmental directive requirements.

Typical Applications

• High-grade audio amplifiers — Power supply filtering and bulk energy storage to support high-fidelity amplification stages and improve tone stability.
• HD audio playback systems — Used where low loss and stable capacitance contribute to meeting high tone quality requirements for HD Audio equipment.
• Audio power supply modules — Snap-in mounting and 80 V rating suit power rails and decoupling in professional and consumer audio equipment.

Unique Advantages
