LKG1E223MESBAK

The LKG1E223MESBAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, designed for audio equipment. It provides 22,000 µF capacitance at a 25 V rating in a compact φ30 × 45 mm can, optimized for high‑capacity filtering and reservoir functions in audio applications.

Key electrical and mechanical characteristics include a 3.85 A ripple current rating (120 Hz), a leakage current specification of 2,220 µA, a ±20% capacitance tolerance, and an operating temperature range of −40°C to +85°C with 1,000 hours endurance at 85°C. Note: this part is listed as End Of Life.

Key Features

• High Capacitance, 25 V rating — 22,000 µF at 25 V delivers bulk energy storage for low‑frequency smoothing and reservoir duties in audio power stages.
• Snap‑in, radial can package — Snap‑in mounting provides secure chassis or board installation for through‑hole assemblies; package dimensions are approximately φ30 × 45 mm (L: 4.5 cm × D: 3 cm).
• Ripple current capability — Rated ripple current of 3.85 A at 120 Hz supports demanding AC ripple conditions common in amplifier power supplies.
• Leakage and tolerance — Specified leakage current of 2,220 µA and capacitance tolerance of ±20% enable predictable filter performance when used within rated conditions.
• Operating range and endurance — Designed for −40°C to +85°C operation with an endurance rating of 1,000 hours at 85°C.
• Polarized construction — Conventional polarized aluminum electrolytic design for DC power supply applications.
• RoHS compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• High‑fidelity audio amplifiers — Bulk reservoir and smoothing capacitor to support stable supply rails and reduce low‑frequency ripple in audio amplifier stages.
• Studio and professional audio equipment — Energy storage and decoupling in power distribution for mixers, preamps, and other pro audio gear where high capacitance is required.
• Consumer audio electronics — Power supply filtering and transient support in hi‑fi and home theater components designed for high‑quality sound reproduction.

Unique Advantages

• Large capacitance in a compact can — 22,000 µF in a φ30 × 45 mm package provides substantial energy density for space‑constrained audio designs.
• Robust ripple handling — 3.85 A ripple current rating at 120 Hz helps minimize heating and maintain stability under AC stress.
• Wide operating temperature range — −40°C to +85°C supports reliable operation across common environmental conditions for audio equipment.
• Designed for audio use — Part of Nichicon’s LKG series specifically developed for audio equipment, aligning electrical characteristics with audio power supply needs.
• Predictable endurance — 1,000 hours at 85°C endurance rating gives a defined reliability expectation for thermal stress over time.
• RoHS compliance — Meets environmental regulatory requirements for lead‑free electronic assemblies.
