Overview of LKG1J392MESBBK – Aluminum Electrolytic Capacitor, Snap-in, 3900 µF, 63 V

The LKG1J392MESBBK is a snap-in, polarized aluminum electrolytic capacitor from Nichicon's LKG series, specified at 3.9 mF (3900 µF) and 63 V. It is designed for audio equipment and related applications that require an audio-oriented capacitor form factor and performance characteristics documented for the LKG family.

Key electrical and reliability parameters include a rated voltage of 63 V, capacitance tolerance of ±20%, low-frequency ripple current capability of 3.35 A (120 Hz), a specified tan δ of 0.3, and an endurance rating of 1000 hours at 85 °C. Note: this part is listed as End of Life.

Key Features

  • Capacitance & Voltage — 3.9 mF (3900 µF) rated at 63 V with ±20% tolerance, suitable where high capacitance and moderate voltage are required.
  • Audio-oriented design — Part of the LKG series specified "For Audio Use" and "For Audio Equipment" in the series documentation.
  • Ripple and loss characteristics — Ripple current specified at 3.35 A (120 Hz) and a tangent of loss angle (tan δ) given as 0.3 to describe AC loss behavior at the specified measurement conditions.
  • Leakage current — Initial leakage current value provided as 1480 µA (measurement conditions per datasheet extraction).
  • Endurance and temperature range — Rated for 1000 hours at 85 °C; operating temperature range −40 °C to +85 °C as specified for the series.
  • Snap-in package & form factor — Radial can with snap-in terminals, case size φ30 × 45 mm length (approx. L: 4.5 × D: 3.0 cm) for board-mount snap-in installations; marked with gold-color lettering on a black sleeve per series marking convention.
  • RoHS compliant — Documented as RoHS compliant in the product data.

Typical Applications

  • Audio Equipment — Specified for "For Audio Use" and "For Audio Equipment" in the LKG series documentation; suitable where a 3.9 mF, 63 V polarized snap-in capacitor is required.
  • High-fidelity electronic assemblies — Applicable in assemblies that reference the LKG series for audio-grade components and the listed electrical characteristics (tan δ, ripple current, leakage current, temperature range).
  • Power filtering in audio systems — Fits designs that require the documented ripple current rating (3.35 A at 120 Hz) and the endurance specification of 1000 hours at 85 °C.

Unique Advantages

  • Audio-series specification: The LKG family is explicitly documented for audio use, providing a clear product choice for audio-focused designs.
  • High capacitance in a snap-in can: 3.9 mF at 63 V delivered in a radial, snap-in package simplifies mounting and board retention for high-capacitance needs.
  • Measured AC performance data: Specified tan δ and ripple current figures allow engineers to evaluate AC loss and ripple-handling against system requirements.
  • Wide operating temperature span: Rated from −40 °C to +85 °C to match the documented ambient conditions for the series.
  • Documented endurance: Endurance specified as 1000 hours at 85 °C, enabling lifecycle planning based on the datasheet endurance criteria.
  • Regulatory compliance: RoHS compliance is stated in the product information.

Why Choose LKG1J392MESBBK?

LKG1J392MESBBK is positioned as an LKG-series snap-in aluminum electrolytic capacitor tailored for audio equipment applications where a 3.9 mF, 63 V polarized capacitor with defined ripple, loss, leakage, and endurance specifications is required. Its combination of capacitance, rated voltage, and documented AC and endurance parameters makes it suitable for engineers specifying audio-oriented capacitors within that performance envelope.

This component is appropriate for designers and procurement teams specifying parts from Nichicon's LKG family for audio-focused electronic assemblies. Use the published specifications—capacitance, voltage, tan δ, ripple current, leakage current, temperature range, and endurance—to assess fit against your design requirements.
