LKG2A122MESZAK

The LKG2A122MESZAK is an aluminum electrolytic snap‑in capacitor from Nichicon’s LKG series, designed specifically for high‑grade audio equipment. It pairs a 1.2 mF (1200 µF) capacitance with a 100 V rated voltage in a radial, can‑style snap‑in package for robust board mounting.

This part is intended for audio applications where fidelity and reliable power conditioning are important. Key operational characteristics include a rated lifetime of 1000 hours at 85 °C, a rated ripple current of 2.2 A (120 Hz), and RoHS compliance. Note: this part is marked End Of Life.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 100 V rated voltage and ±20% tolerance for bulk energy storage and power supply smoothing.
• Audio‑Oriented Design — Part of the LKG series developed for audio equipment; designed to prioritize high‑fidelity sound quality in audio power circuits.
• Snap‑In, Radial Can Package — Snap‑in terminal mounting (radial, can – snap‑in) for secure mechanical attachment and simplified assembly into chassis or PCBs.
• Ripple Current Handling — Rated ripple current of 2.2 A at 120 Hz to support power supply filtering in amplifier and audio power stages.
• Leakage Current — Specified leakage current around 1030 µA (as provided), suitable for evaluating standby and bias current budgets.
• Environmental & Lifetime — RoHS compliant with an endurance rating of 1000 hours at 85 °C; operating temperature range from −40 °C to +85 °C.
• Compact Dimension — Body diameter φ22 × 40 mm length (approx. 2.2 × 4.0 cm), tray packing for handling and assembly.
• Polarized — Intended for DC power applications; follow polarity markings during installation.

Typical Applications

• High‑Fidelity Amplifiers — Bulk filtering and power smoothing in amplifier power supplies where audio quality and stable supply rails matter.
