LKG1K122MESBBK

The LKG1K122MESBBK is a snap‑in, polarized aluminum electrolytic capacitor from the Nichicon LKG series, engineered for audio equipment. It delivers 1.2 mF capacitance at an 80 V rating in a compact φ30 × 25 mm snap‑in can for board‑mounted power and smoothing applications.

Designed with audio performance in mind, the LKG series emphasizes high‑tone quality and fidelity while providing practical electrical characteristics such as low‑frequency ripple handling, controlled dissipation factor, and proven endurance at elevated temperature.

Key Features

• Capacitance & Tolerance — 1.2 mF (1200 µF) with a tolerance of −20% to +20% at 120 Hz, 20 °C.
• Rated Voltage — 80 V DC rating suitable for high‑voltage audio power stages.
• Dissipation Factor (tan δ) — tan δ = 0.25 (measured at 20 °C, 120 Hz, 80 V), supporting stable audio performance.
• Low‑Frequency Ripple Handling — 2.4 A ripple current capability at 120 Hz for effective smoothing in low‑frequency power circuits.
• Leakage Current — 920 µA (series leakage characteristic; series datasheet specifies measurement after voltage application at 20 °C).
• Temperature Range & Endurance — Rated for −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C per series test conditions.
• Package & Mounting — Snap‑in radial can (φ30 × 25L) for secure board mounting; supplied in tray packing.
• RoHS Compliance — Manufactured in compliance with RoHS requirements noted for the series.

Typical Applications

• High‑grade audio amplifiers — Bulk smoothing and power filtering in power supplies for high‑fidelity audio equipment.
• Professional audio systems — Energy storage and low‑frequency ripple suppression in mixers, preamps, and power amps.
• Audio signal power rails — Decoupling and reservoir capacitance where stable dissipation factor and controlled leakage support consistent tone quality.

Unique Advantages

• Audio‑focused design: The LKG series is specified for high‑grade audio equipment, prioritizing tone quality for HD audio applications.
• High ripple capability: 2.4 A ripple current at 120 Hz reduces low‑frequency ripple on power rails, improving downstream audio performance.
• Controlled dissipation factor: A tan δ of 0.25 (20 °C, 120 Hz) helps maintain predictable thermal and electrical behavior in audio circuits.
• Compact snap‑in package: φ30 × 25 mm snap‑in can simplifies board layout and mechanical retention for through‑hole assemblies.
• Temperature endurance: Rated operation from −40 °C to +85 °C with 1000‑hour endurance at 85 °C provides defined reliability under elevated temperature stress.
• RoHS compliant: Meets series RoHS directive conformance for regulated material requirements.
