LKG1H182MESAAK

The LKG1H182MESAAK from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LKG series, specified at 1800 µF (1.8 mF) and 50 V. It is a TYPE‑I (Gold Tune) low‑profile part developed for high‑grade audio equipment where high fidelity and tonal quality are priorities.

Designed with a compact radial can (snap‑in) package and polarization, this capacitor delivers audio‑focused performance with a rated operating temperature range of −40 °C to +85 °C and a 1000‑hour endurance at 85 °C.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 50 V, suitable for audio power filtering and decoupling in high‑fidelity equipment.
• TYPE‑I (Gold Tune) Grade — Low‑profile, high‑tone quality grade using a developed electrolyte formulation targeted at HD audio applications.
• Package & Mounting — Snap‑in terminal, radial can construction for secure chassis or board mounting and robust mechanical retention.
• Size — Compact footprint: 25 mm diameter × 20 mm length (approx. 2.5 cm × 2.0 cm), helping conserve space in audio assemblies.
• Tolerance & Loss — Capacitance tolerance ±20% (120 Hz, 20 °C) and specified loss tangent (tan δ) of 0.3, enabling predictable frequency response in filter circuits.
• Ripple Handling & Polarization — Rated ripple current 1.65 A at 120 Hz; polarized design for DC smoothing and power reservoir functions.
• Reliability & Endurance — Rated for 1000 hours at 85 °C. Endurance criteria include capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current not exceeding initial specified value after test.
• Leakage Current Specification — After 5 minutes at rated voltage and 20 °C, leakage current is specified as not more than 3√(C·V) μA (C in μF, V in V).
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio amplifiers — Use as power supply smoothing and reservoir capacitors to support stable, low‑noise DC rails in high‑fidelity amplifier stages.
• Preamp and signal chain circuits — Employed where tonal characteristics and low loss are important for preserving audio quality.
• Audio power supplies — Suitable for bulk decoupling and ripple reduction in power supply modules for HD audio equipment.

Unique Advantages

• Audio‑focused formulation — TYPE‑I Gold Tune grade and the developed electrolyte prioritize tonal quality for HD audio applications.
• Compact, snap‑in form factor — Small diameter and snap‑in mounting enable secure installation while minimizing board or chassis footprint.
• Predictable electrical behavior — Specified tan δ, leakage current formula, and tolerance provide verifiable electrical characteristics for repeatable design outcomes.
• Endurance at elevated temperature — 1000 hours at 85 °C with defined post‑test limits supports deployment in thermally active audio equipment.
• Regulatory compliance — RoHS compliance supports use in designs requiring restricted‑substance conformance.
• Clear marking — Printed with gold color lettering on a black sleeve for straightforward part identification.
