Key Features

• Capacitance and tolerance — 2200 µF nominal (2.2 mF) with tolerance ±20% at 120 Hz, 20 °C.
• Rated voltage — 80 V DC rating suitable for higher‑voltage audio power rails.
• Ripple handling — Low‑frequency ripple current rated at 3.25 A (120 Hz), applicable for power reservoir applications within audio circuits.
• Loss tangent (tan δ) — tan δ 0.25 measured at 20 °C, 120 Hz, providing a defined dissipation characteristic for audio designs.
• Leakage current — Specified leakage current of 1250 µA after rated voltage application.
• Endurance — Life specified as 1000 hours at 85 °C with capacitance change within ±20%, tan δ within 200% of initial, and leakage current ≤ initial specified value after test.
• Operating temperature range — −40 °C to +85 °C for use across common ambient conditions in audio equipment.
• Package and mounting — Radial, large can snap‑in construction (φ35 × 30 mm length) for robust mechanical retention on assemblies.
• RoHS compliant — Conforms to applicable RoHS directive requirements as noted for the LKG series.

Typical Applications

• Audio equipment — Intended for high‑grade audio equipment where series design and specifications target audio performance needs.
• High‑fidelity amplifiers — Suitable for use in audio amplifier assemblies that require a radial snap‑in electrolytic capacitor with defined endurance and ripple specifications.
• Audio power supply modules — Appropriate for power rail energy storage in audio power supplies, leveraging the 80 V rating and 3.25 A ripple capability.

Unique Advantages

• Audio‑focused design: Part of the LKG series, designed specifically for high‑grade audio equipment, aligning component selection with sonic and electrical priorities for audio systems.
