LKG1C273MESCAK

The LKG1C273MESCAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, designed for audio equipment. It provides 27,000 µF capacitance at a 16 V rating in a radial, snap‑in can package intended for high‑fidelity audio applications.

Engineered for audio power supply and filtering roles, this capacitor combines large bulk capacitance, a measured tanδ of 0.45 (20°C, 120 Hz), and a 3.35 A low‑frequency ripple current rating (120 Hz) to support stable low‑frequency performance in audio systems. It is RoHS compliant and rated for -40°C to +85°C operation with a 1,000 hour endurance at 85°C.

Key Features

• High Capacitance — 27,000 µF nominal capacitance for energy storage and smoothing in audio power supplies.
• Rated Voltage — 16 V working voltage suitable for low‑voltage audio power rails.
• Audio‑Grade Series — Part of the LKG series designed for audio equipment; the part number suffix AK identifies the TYPE‑I (Gold Tune) grade in the series documentation.
• Electrical Loss — Tangent of loss angle (tanδ) specified at 0.45 (measured at 20°C, 120 Hz), enabling assessment of dissipation for audio use.
• Ripple Handling — Low‑frequency ripple current rating of 3.35 A at 120 Hz for reservoir and smoothing tasks in audio supplies.
• Leakage Current — Specified leakage current of 1,970 µA for initial leakage assessment during design.
• Package & Mounting — Radial, snap‑in can package (snap‑in mounting) with dimensions φ35 × 30 mm length for board or chassis mounting.
• Temperature & Endurance — Operating range -40°C to +85°C with endurance of 1,000 hours at 85°C.
• Compliance & Packing — RoHS compliant; shipped in tray packing.
• Polarized — Designated polarized capacitor for correct orientation in DC circuits.

Typical Applications

• Audio power supplies — Bulk energy storage and smoothing in amplifier power rails where large capacitance at 16 V is required.
• High‑fidelity audio equipment — Intended for use in high‑grade and HD audio equipment as specified by the LKG series documentation.
• Reservoir/filter capacitors — Low‑frequency ripple handling and large capacitance make it suitable for reservoir and smoothing duties in audio electronics.

Unique Advantages

• Large energy storage — 27,000 µF provides substantial charge reservoir for audio power stages, reducing supply sag during dynamic passages.
• Measured electrical parameters — Specified tanδ (0.45 at 20°C, 120 Hz) and leakage current (1,970 µA) let designers evaluate dissipation and standby losses precisely.
• Robust ripple capability — 3.35 A ripple current (120 Hz) supports sustained low‑frequency ripple currents typical of audio power supplies.
• Audio‑focused series — Part of Nichicon’s LKG audio series with a TYPE‑I (Gold Tune) grade designation, aligning the component with high‑tone quality audio designs.
• Wide temperature operation — -40°C to +85°C rating and 1,000 hour endurance at 85°C provide predictable behavior across common audio operating environments.
• RoHS compliant — Conforms to RoHS requirements for environmentally regulated designs.
