LKG1J222MESABK

The LKG1J222MESABK from Nichicon is a snap‑in, radial can aluminum electrolytic capacitor engineered for high‑grade audio equipment. It belongs to the LKG series and is specified as TYPE‑II, the center grade optimized for high tone quality using electrode foil intended for best sound reproduction.

This capacitor provides a polarized 2.2 mF capacitance at a 63 V rating, with a compact package footprint and specifications tuned for audio applications that require stable performance across a wide temperature range and defined endurance at elevated temperature.

Key Features

• Capacitance & Voltage — 2.2 mF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Audio‑Focused Grade — Designated TYPE‑II in the LKG series, employing electrode foil intended to deliver the high tone quality required for HD audio equipment.
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure PCB retention in radial, can‑style packaging; package dimensions L: 3.5 × D: 2.5 cm.
• Operating Temperature Range — Rated for −40°C to +85°C to cover common environmental conditions encountered in audio systems.
• Endurance — Specified for 1000 hours at 85°C with limits: capacitance change within ±20%, tan δ up to 200% of initial, and leakage current not exceeding initial specified value after test.
• Ripple Current — Low‑frequency ripple handling of 2.75 A at 120 Hz, suitable for power supply smoothing in audio circuits.
• Leakage Current Specification — Leakage current defined by the series formula: not more than 3√(C·V) μA after 5 minutes at rated voltage and 20°C.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Visual Identification — Marked with gold color lettering on a black sleeve for clear grade identification.

Typical Applications

• High‑grade Audio Amplifiers — Bulk and decoupling capacitance in amplifier power stages where tonal neutrality and stable filtering are important.
• HD Audio Equipment — Power supply smoothing and energy storage in audio devices specified for high tone quality.
• Professional Audio Electronics — Applications requiring snap‑in mounting and reliable long‑term performance at elevated operating temperature.
