LKG1K222MESZAK

The LKG1K222MESZAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series designed for audio use. It delivers 2200 µF capacitance at an 80 V rating in a radial, snap‑in can package sized φ22 × 45 mm.

Engineered for high‑grade audio equipment, this part combines elevated capacitance and voltage handling with a 1000‑hour endurance at 85°C and an operating range from −40°C to 85°C to support demanding audio system requirements.

Key Features

• Capacitance & Voltage — 2200 µF rated capacitance at 80 V provides bulk energy storage for audio system power rails and filtering.
• Audio‑Focused Design — Part of the LKG series specified “For Audio Use,” developed with tone quality considerations suitable for high‑grade and HD audio equipment.
• Snap‑in Mounting — Radial, can snap‑in terminal package simplifies board assembly for chassis‑mounted power sections.
• Thermal and Life Specifications — Rated for an operating temperature range of −40°C to +85°C with a guaranteed endurance of 1000 hours at 85°C.
• Ripple and Leakage — Low‑frequency ripple current rating of 2.7 A (120 Hz) and specified leakage current of 1250 µA for predictable performance under load.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.
• Compact Footprint — Physical dimensions L: 45 mm × D: 22 mm (φ22 × 45L) provide a space‑efficient solution for power sections in audio equipment.

Typical Applications

• High‑grade audio equipment — Suitable for use where audio fidelity and stable power delivery are priorities.
• HD audio systems — Designed to meet tone quality requirements for HD audio applications within the LKG series scope.
• Chassis‑mounted power modules — Snap‑in radial can package designed for secure mounting in power supply assemblies common in audio electronics.

Unique Advantages

• High energy storage at elevated voltage: 2200 µF at 80 V provides substantial reserve for audio power rails without increasing package diameter.
• Audio‑oriented engineering: Part of a series developed specifically “For Audio Use,” offering tone‑quality consideration relevant to high‑fidelity designs.
• Durability under thermal stress: 1000 hours endurance at 85°C supports sustained operation in thermally demanding enclosures.
• Predictable ripple handling: 2.7 A ripple current (120 Hz) rating enables reliable AC stress performance in low‑frequency power environments.
• RoHS compliance: Meets RoHS directive requirements for environmentally conscious designs.
• Compact, serviceable package: Snap‑in radial can simplifies mechanical retention and replacement in assembled audio equipment.
