LKG1H182MESZCK

The LKG1H182MESZCK from Nichicon is an aluminum electrolytic capacitor in a radial, snap‑in can package, optimized for high‑grade audio applications. It delivers 1.8 mF capacitance at a 50 V rating with polarized terminals and is designed with priority on high‑fidelity sound quality for HD audio equipment.

Compact and serviceable in audio power supplies and amplifier reservoirs, this LKG series component combines measurable electrical characteristics—such as low loss (tan δ), specified ripple capability, and defined endurance—for reliable audio performance in professional and consumer HD audio systems.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 50 V with ±20% tolerance, providing bulk energy storage for audio power rails.
• Low Loss — tan δ = 0.22 (measurement frequency: 120 Hz at 20 °C), supporting cleaner audio supply filtering where low dissipation is important.
• Ripple Current — Rated ripple current of 2.45 A at 120 Hz, suitable for smoothing and decoupling in power stages of audio equipment.
• Operating Temperature & Endurance — Specified for −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C under rated voltage; capacitance change remains within ±20% after endurance testing.
• Stability at Low Temperature — Impedance limits of Z(−25 °C)/Z(+20 °C) ≤ 4 and Z(−40 °C)/Z(+20 °C) ≤ 12 (measured at 120 Hz), aiding performance in cold environments.
• Leakage Current — After 5 minutes at 20 °C and rated voltage, leakage current is limited to ≤ 3√(C·V) μA (C in μF, V in V), providing predictable standby behavior.
• Package & Mounting — Radial, snap‑in can (snap‑in terminal) for secure board mounting; dimensions approximately Ø22 mm × 50 mm length for compact chassis integration.
• Identification — Marked with gold‑color lettering on a black sleeve for clear part identification.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade Audio Equipment — Bulk filtering and reservoir duties in Hi‑Fi amplifiers and preamplifiers where prioritizing fidelity is required.
• HD Audio Systems — Power supply smoothing and decoupling in HD audio components to help meet high‑tone quality requirements.
• Professional Amplifiers — Energy storage and ripple handling in amplifier power stages, taking advantage of the rated ripple current and low loss.

Unique Advantages

• Engineered for audio fidelity — Designed specifically for high‑grade audio use with an emphasis on high‑tone quality for HD audio equipment.
• Measurable low dissipation — Specified tan δ = 0.22 at 120 Hz supports predictable low loss behavior in audio signal power domains.
• Defined endurance — 1000 hours at 85 °C with controlled capacitance and leakage characteristics ensures long‑term stability under rated conditions.
• Compact snap‑in form factor — Radial snap‑in can delivers secure board mounting in compact audio chassis while providing sizable capacitance for its footprint.
• Clear part identification — Gold lettering on black sleeve simplifies inventory and serviceability.
• RoHS compliant — Meets applicable RoHS directive requirements for reduced restricted substances.
