LKG1H222MESYBK

The LKG1H222MESYBK from Nichicon is a snap‑in aluminum electrolytic capacitor in the LKG series, optimized for audio equipment applications. It provides 2.2 mF (2200 µF) capacitance at a 50 V rating in a radial, can‑style snap‑in package suitable for power smoothing, filtering and energy storage in audio power supplies and related circuits.

Key electrical characteristics include a low‑frequency ripple current rating of 2.35 A (120 Hz), measured dissipation factor (tan δ) of 0.3 at 20 °C / 120 Hz, and a rated endurance of 1000 hours at 85 °C. The unit ships in tray packing and is RoHS compliant.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with a 50 V rated voltage, suitable for mid‑voltage audio power rails.
• Snap‑In Mounting — Radial, can‑type snap‑in package designed for secure vertical board mounting and ease of assembly.
• Ripple Current Capacity — Low‑frequency ripple current rated at 2.35 A (120 Hz), supporting power smoothing under typical audio supply ripple conditions.
• Electrical Loss (tan δ) — Dissipation factor of 0.3 measured at 20 °C and 120 Hz, useful for estimating AC loss in audio circuits.
• Leakage Current — Specified leakage current of 990 µA, allowing predictable bias behavior after voltage application.
• Temperature & Endurance — Operating range from −40 °C to +85 °C with rated life of 1000 hours at 85 °C, per endurance specification.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% at 120 Hz / 20 °C; polarized device for DC applications.
• Form Factor — Compact footprint: diameter φ20 mm × length 45 mm (L: 4.5 cm × D: 2.0 cm), packaged in trays for handling and assembly.

Typical Applications

• High‑fidelity audio amplifiers — Bulk filtering and power decoupling on amplifier supply rails to support stable audio performance.
