LKG1V392MESYBK

The LKG1V392MESYBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, optimized for audio applications. It delivers 3.9 mF capacitance at 35 V in a radial, snap‑in can (φ20 × 45 mm) package designed for high‑grade audio equipment where fidelity and reliable power conditioning are priorities.

Targeted as a TYPE‑II grade device within the LKG family, this part emphasizes audio‑focused electrode construction and multiple‑use suitability while meeting RoHS requirements.

Key Features

• Audio‑grade construction (TYPE‑II)  Center grade electrode foil designed for high‑fidelity audio use and multi‑purpose applications within the LKG series.
• Capacitance & voltage  3.9 mF (3900 µF) nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Package & mounting  Radial, snap‑in can (φ20 × 45 mm) for secure chassis or board mounting in audio assemblies.
• Operating temperature range  –40°C to +85°C suitable for typical audio equipment ambient conditions.
• Endurance  Rated for 1000 hours at 85°C with specified limits: capacitance change within ±20%, tan δ up to 200% of initial spec, and leakage current within initial limits after endurance testing.
• Leakage current specification  After 5 minutes’ application of rated voltage at 20°C, leakage current is specified as not more than 3√CV (μA) [C: μF, V: V].
• Low‑temperature impedance stability  Series guidance shows controlled impedance increase at low temperatures: Z(–25°C)/Z(+20°C) up to 4 and Z(–40°C)/Z(+20°C) up to 12.
• Ripple handling  Rated ripple current (low frequency) of 2.4 A at 120 Hz for audio power supply ripple filtering.
• RoHS compliant  Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio equipment  Designed specifically for use in high‑fidelity audio systems where sonic performance and stable power filtering are important.
• HD Audio components  Suited to HD audio devices that require reliable smoothing and decoupling in their power rails.
• Audio power supply filtering  Useful as a reservoir / smoothing capacitor in the power circuits of amplifiers and audio electronics within the specified temperature and endurance limits.

Unique Advantages

• Audio‑centric electrode design  TYPE‑II electrode foil and LKG series development focus the part toward fidelity and audible performance in audio systems.
