LKG1E222MESACK

The LKG1E222MESACK is a Nichicon LKG series aluminum electrolytic capacitor in a snap‑in radial can. It provides 2200 µF of capacitance at a 25 V rating with snap‑in terminals for secure PCB mounting in power supply and audio circuits.

Engineered for audio equipment, the LKG series emphasizes high‑fidelity performance. This part combines high ripple‑current capability, controlled dissipation (tan δ), and a 1000‑hour endurance at 85 °C to support demanding audio power applications and smoothing tasks.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in low‑voltage power rails.
• Audio‑grade design — Part of Nichicon’s LKG series developed for audio equipment to prioritize high‑fidelity sound characteristics.
• Low loss (tan δ) — Specified tangent of loss angle of 0.22 (measurement conditions per series datasheet), supporting stable performance in audio circuits.
• High ripple handling — Rated ripple current of 1.8 A at 120 Hz for effective filtering of power supply ripple in amplifier and preamplifier stages.
• Reliability and lifetime — Endurance rated at 1000 hours at 85 °C; leakage current specified (product listing: 700 µA) and endurance criteria per series datasheet.
• Mounting & package — Snap‑in radial can package (φ25 × 30 mm length) for secure board retention and easy insertion during assembly; tray packing.
• Operating temperature range — −40 °C to +85 °C to cover typical equipment enclosure and ambient conditions.

Typical Applications

• Audio power supplies — Bulk smoothing and ripple suppression in amplifier and preamplifier power rails where stable DC and low noise are required.
• High‑fidelity audio equipment — Decoupling and reservoir capacitance in professional and consumer audio gear that benefit from the LKG series’ audio‑oriented design.
• AV and studio electronics — Power conditioning in mixers, processors, and outboard equipment that require sustained ripple handling and endurance at elevated temperatures.

Unique Advantages

• Designed for audio fidelity — The LKG series focus on sound quality makes this capacitor suitable where audio performance is a priority.
• Robust ripple current capability — 1.8 A at 120 Hz reduces voltage ripple under load, improving supply stability for sensitive analog stages.
• Controlled dissipation factor — tan δ = 0.22 supports predictable AC behavior and stability in filtering networks.
• Endurance at elevated temperature — Rated 1000 hours at 85 °C for predictable long‑term performance in warm operating environments.
• Secure snap‑in mounting — Radial snap‑in can simplifies mechanical retention on PCBs and helps streamline assembly.
• Wide ambient tolerance — −40 °C to +85 °C operating range accommodates a wide range of application environments.
