LKSA2103MESC

The LKSA2103MESC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general‑purpose electronics. This smaller‑sized, polarized radial can offers 10 mF capacitance at a 42 V rating, delivering higher tonal quality when used as a replacement for small standard parts.

Engineered for board‑level snap‑in mounting, the part combines a compact footprint (L: 3 × D: 3.5 cm) with a robust ripple current rating and a broad operating temperature range to support power‑filtering roles in audio and other electronic systems.

Key Features

• Capacitance & Voltage — 10 mF capacitance rated at 42 V for energy storage and smoothing in power circuits.
• Package & Mounting — Radial, can-style snap‑in terminal type for secure board mounting and straightforward assembly.
• Audio‑focused Design — LKS series described as smaller and delivering improved tone quality compared to standard small products, intended for audio equipment use.
• Operating Range & Lifetime — Rated for –40 °C to +85 °C with a specified lifetime of 1,000 hours at 85 °C.
• Ripple Current — Supports 3.5 A ripple current at 120 Hz, enabling effective smoothing in high‑demand power stages.
• Tolerance & Polarization — Capacitance tolerance of ±20% (at 120 Hz, 20 °C); polarized electrolytic construction.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Leakage Current Specification — Leakage current after 5 minutes’ application of rated voltage at 20 °C is ≤ 3√(C·V) μA, where C is rated capacitance (μF) and V is voltage (V).

Typical Applications

• Audio Equipment — Used in audio power supplies and signal‑path support where replacing smaller standard capacitors can improve tonal quality.
• Power Supply Smoothing — Bulk filtering and reservoir duties in low‑to‑medium power supply stages benefiting from the 3.5 A ripple current rating.
• General‑Purpose Electronics — Board‑level energy storage and decoupling in a variety of electronic systems that require snap‑in mount solutions.

Unique Advantages

• Audio‑oriented performance: LKS series design targets improved tone quality when replacing smaller standard capacitors in audio assemblies.
• High ripple capability: 3.5 A ripple current at 120 Hz supports demanding smoothing tasks in power stages.
• Wide ambient tolerance: Operation from –40 °C to +85 °C makes the part suitable for varied environmental conditions.
