LKG1V392MESCBK

The LKG1V392MESCBK is a Nichicon LKG series aluminum electrolytic capacitor in a snap‑in radial can package, specified at 3.9 mF (3900 µF) and 35 V. It is developed for high‑grade audio equipment and HD Audio applications where fidelity and stable power filtering are priorities.

This part is the LKG series TYPE‑II (center grade) audio variant, offering a compact φ35 × 20 mm profile with snap‑in terminals for secure chassis or PCB mounting, RoHS compliance, and performance characteristics tuned for audio power systems.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance at 35 V rated voltage, with a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Audio‑focused Grade (TYPE‑II) — Center grade LKG series construction intended to prioritize sound quality in high‑grade and HD Audio equipment.
• Snap‑in Mounting & Package — Radial, can‑type snap‑in package for reliable mechanical retention and straightforward assembly into audio power modules or chassis.
• Compact Dimensions — Diameter φ35 mm, length 20 mm (L: 2.0 cm × D: 3.5 cm), supporting low‑profile board and chassis layouts.
• Operating Temperature — Specified for operation from −40 °C to +85 °C.
• Ripple Current — Rated ripple handling of 2.5 A at 120 Hz (useful for smoothing and decoupling in low‑frequency audio power supplies).
• Reliability / Endurance — Life specification: 1000 hours at 85 °C with the rated voltage applied. After endurance, capacitance change is within ±20%, tan δ remains within 200% of initial specified value, and leakage current remains at or below the initial specified value.
• Leakage Current Specification — After 5 minutes at rated voltage and 20 °C, leakage current is not more than 3√(C·V) μA (where C is μF and V is volts), per the LKG series specification.
• Polarized — Electrolytic polarized construction for DC power filtering applications.
• Marking & Compliance — Sleeve marking is printed in gold on a black sleeve; the part is RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade Audio Amplifiers — Power supply smoothing and decoupling where stable low‑frequency energy storage supports consistent audio performance.
• HD Audio Components — Use in preamplifiers, DAC power stages, and other HD Audio modules that prioritize fidelity and low‑noise power rails.
• Studio and Pro‑AV Equipment — Filtering and bulk energy storage in equipment racks and standalone audio processors requiring compact, low‑profile capacitors.

Unique Advantages

• Audio‑focused construction: TYPE‑II center grade design tailored to the LKG series objective of prioritizing sound quality in high‑grade audio applications.
• Compact, low‑profile form factor: φ35 × 20 mm package enables installation in space‑constrained amplifier and audio chassis designs.
• Secure snap‑in mounting: Snap‑in terminal package simplifies assembly and provides reliable mechanical retention for chassis and board installations.
• Measurable ripple capability: 2.5 A ripple at 120 Hz supports effective smoothing in low‑frequency audio power supplies.
• Documented endurance: 1000 hours at 85 °C with specified limits on capacitance change, tan δ, and leakage current for predictable long‑term behavior.
• RoHS compliance and identifiable marking: Conforms to RoHS directives and is marked with gold lettering on a black sleeve for easy identification.
