LKG1E222MESABK

The LKG1E222MESABK is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LKG series designed for audio equipment. It is a Type‑II (BK) grade part tuned for balanced high‑fidelity audio performance within the LKG family.

With a 2.2 mF (2200 µF) capacitance at 25 V rating, a compact φ25 × 20 mm can package and snap‑in mounting, this capacitor targets power‑supply filtering and decoupling roles in professional and consumer audio systems where stable performance and audible quality matter.

Key Features

• Electrical Performance — 2.2 mF (2200 µF) nominal capacitance at 25 V with ±20% tolerance (120 Hz, 20°C), suitable for bulk filtering and energy storage in audio power rails.
• Low-loss Characteristic — Specified tan δ of 0.3 (measured at 120 Hz, 20°C), supporting lower dissipation in audio power circuits.
• Ripple Handling — Rated ripple current of 1.5 A at 120 Hz, enabling effective smoothing of rectified supplies in amplifier and preamplifier stages.
• Leakage Current — Typical leakage current listed as 700 µA, consistent with electrolytic behaviour and useful for power‑budget calculations.
• Reliability and Endurance — Endurance specified as 1000 hours at 85°C; capacitors restored to 20°C after endurance meet capacitance, tan δ and leakage requirements per the series specification.
• Temperature Range & Stability — Operating range from −40°C to +85°C with low‑temperature impedance characteristics defined in the LKG series documentation (Z(-25°C)/Z(+20°C) and Z(-40°C)/Z(+20°C) limits available in the datasheet).
• Package & Mounting — Radial, can-type snap‑in package (φ25 × 20 mm) for secure board retention and straightforward chassis or PCB mounting.
• Environmental Compliance — RoHS compliant.

Typical Applications

• High-fidelity audio amplifiers — Bulk smoothing and power-rail decoupling to support low-noise amplifier operation and steady supply during dynamic audio passages.
• Professional audio equipment — Power supply filtering in mixers, preamplifiers and studio gear where consistent performance over long operating periods is required.
• Consumer audio electronics — Energy storage and ripple reduction in CD players, DACs and integrated receivers to help maintain audio clarity.

Unique Advantages

• Audio-focused series design: Part of the Nichicon LKG family explicitly developed for audio use, providing characteristics tuned toward high‑fidelity sound reproduction.
• Balanced performance profile: TYPE‑II (BK) grade selection offers a center grade tradeoff between tone quality and general purpose use within the LKG series.
• High ripple capability: 1.5 A ripple current rating at 120 Hz allows reliable smoothing in moderate‑power audio power supplies.
• Compact snap‑in form factor: φ25 × 20 mm can with snap‑in terminals simplifies mechanical installation while keeping board space and height requirements modest.
• Endurance at elevated temperature: 1000 hours at 85°C endurance specification supports sustained operation in warm enclosures and long‑term reliability planning.
• RoHS compliant: Meets environmental regulatory requirements for lead‑free assemblies.
