Key Features

• Capacitance & Tolerance — Rated at 820 µF with a capacitance tolerance of ±20% (measured at 120 Hz, 20 °C), suitable for bulk filtering and energy storage in power rails.
• Rated Voltage — 50 V nominal rating for mid‑voltage audio power supply applications.
• Audio‑grade LKG Series — Part of Nichicon’s LKG family designed for high‑grade audio equipment, prioritizing sound quality in HD audio systems.
• Loss Tangent (tan δ) — Specified at 0.3, with tan δ measurement referenced at 120 Hz and 20 °C for assessing ESR‑related behavior.
• Temperature & Endurance — Operating range from −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C, meeting the LKG series endurance criteria after voltage application.
• Ripple Current — Rated for 1 A ripple current at 120 Hz, supporting typical power supply ripple conditions in audio equipment.
• Leakage Current Specification — After 5 minutes’ application of rated voltage at 20 °C, leakage current is specified as not more than 3√CV (µA), where C is capacitance (µF) and V is voltage (V).
• Construction & Mounting — Radial can with snap‑in terminals provides a robust snap‑in mounting option for chassis or board mounting patterns.
• RoHS Compliant — Manufactured in compliance with RoHS directives.
• Identification — Marked with gold color lettering on a black sleeve for clear series identification.

Typical Applications

• High‑fidelity Audio Amplifiers — Bulk supply filtering and reservoir capacitance to support stable power rails and low audible noise in amplifier stages.
• Professional Audio Equipment — Power smoothing and decoupling in mixers, preamps, and studio systems where consistent tonal characteristics are important.
• Audio Power Supplies — Energy storage and ripple attenuation in regulated and unregulated audio power supplies operating up to 50 V.

Unique Advantages

• Audio‑focused design: Part of the LKG family explicitly designed for high‑grade audio equipment, supporting designers targeting improved sound fidelity.
• High capacitance in a snap‑in package: 820 µF in a radial, snap‑in can enables compact, serviceable mounting for power sections of audio systems.
• Measured low‑frequency performance: Ripple current rating (1 A at 120 Hz) and specified tan δ support predictable behavior under typical audio power conditions.
• Wide operating temperature and proven endurance: −40 °C to +85 °C range with 1000 hours endurance at 85 °C provides reliable performance across typical commercial audio environments.
• Traceable quality marking: Gold lettering on a black sleeve simplifies identification during assembly and maintenance.
