LKS2A392MESC

The LKS2A392MESC is a snap-in terminal aluminum electrolytic capacitor in Nichicon’s LKS series, optimized for audio equipment and general-purpose electronic designs. Its smaller-sized radial can and audio-oriented construction are intended to provide an audible tone-quality improvement when replacing smaller standard capacitors.

Key electrical attributes for this part include a capacitance of 3.9 mF, a 100 V rated voltage, polarization for DC circuits, and RoHS compliance. The device is specified for operation across a wide temperature range and carries endurance ratings useful for sustained operation in typical equipment environments.

Key Features

• Capacitance & Voltage — 3.9 mF nominal capacitance with a 100 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in higher-voltage circuits.
• Snap‑in Radial Can — Snap-in terminal mounting provides a secure mechanical connection for power-supply and chassis-mounted applications.
• Audio‑Oriented Design — Described for use in audio equipment with a smaller-sized construction and design intent to improve tone quality over some small standard products.
• Operating Range & Endurance — Rated for operation from −40 °C to +85 °C with a listed endurance of 1000 hours at 85 °C.
• Ripple Current Capability — Rated ripple current of 4 A at 120 Hz, suitable for smoothing and filtering tasks at line-frequency ripple conditions.
• Polarized Electrolytic — Polarized design for DC power and energy-storage applications.
• Leakage and Loss Characterization — Leakage current specified after 5 minutes’ application of rated voltage as not more than 3√CV (μA); tangent of loss angle (tan δ) measured at 120 Hz, 20 °C per series specifications.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Replacement or upgrade in audio power-supply and coupling positions where improved tonal characteristics are desired compared with smaller standard capacitors.
• Power Supply Filtering — Bulk smoothing and ripple reduction in higher-voltage power supplies where 3.9 mF at 100 V and 4 A ripple capability meet design needs.
• General-Purpose Electronic Equipment — Energy storage and decoupling in industrial and commercial electronics within the −40 °C to +85 °C operating range.

Unique Advantages

• Audio-focused performance: Built to deliver tone-quality improvement when replacing smaller standard parts, making it suitable for audio upgrade and design use.
• High voltage rating: 100 V capability provides headroom for higher-voltage circuits and power stages.
• Robust ripple handling: 4 A ripple current rating at 120 Hz supports effective filtering at line-frequency ripple conditions.
• Durability under load: Endurance specified at 1000 hours at 85 °C gives a measurable baseline for long-term performance planning.
• Clear electrical limits: Leakage current and tan δ are specified per established test conditions, enabling predictable integration into designs.
• Regulatory compliance: RoHS conformity simplifies compliance planning for restricted-substance requirements.
