LKG1J122MESZBK

The LKG1J122MESZBK is an aluminum electrolytic capacitor in a snap‑in radial can package from Nichicon’s LKG series, designed specifically for audio equipment. It combines a 1.2 mF (1200 µF) capacitance with a 63 V rating and is optimized for applications where audio tone quality is a priority.

Key electrical and mechanical attributes include a rated ripple current of 1.95 A at 120 Hz, a specified leakage current value of 820 µA, an operating temperature range of -40 °C to +85 °C, and an endurance rating of 1000 hours at 85 °C. The part is specified as TYPE‑II (BK) within the LKG audio lineup.

Key Features

• Audio‑Optimized LKG Series (TYPE‑II / BK) TYPE‑II (BK) grade in the LKG family, formulated for high‑quality audio equipment where tone quality is emphasized.
• Capacitance & Voltage 1.2 mF (1200 µF) nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Snap‑In Radial Can Package Snap‑in mounting for secure chassis or board attachment; package dimensions approximately L: 3 cm × D: 2.2 cm (φ22×30L).
• Ripple Current Rated ripple current: 1.95 A at 120 Hz, supporting AC ripple handling in audio power circuits.
• Leakage Current Specified leakage current: 820 µA. Datasheet standard: leakage after 5 minutes at 20 °C is not more than 3√(C·V) μA.
• Temperature & Endurance Operating range −40 °C to +85 °C with endurance tested to 1000 hours at 85 °C (capacitance change within ±20% after test).
• Regulatory & Identification RoHS compliant; marked with gold-color lettering on a black sleeve per series marking convention.

Typical Applications

• High‑fidelity audio systems — Suited to high‑grade audio equipment and HD Audio systems where capacitor tone quality is a design consideration.
• Professional audio gear — Appropriate for use in studio and professional audio equipment within the specified voltage and temperature limits.
