LKSN2103MESB

The LKSN2103MESB is an aluminum electrolytic capacitor in a snap-in radial can package designed for audio equipment and general-purpose applications. It delivers a 10 mF capacitance at a 56 V rating with a compact snap-in form factor intended to improve tone quality when replacing smaller standard parts.

Manufactured by Nichicon, this polarized capacitor combines a high ripple-current capability and a specified endurance at elevated temperature, and it is compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 10 mF capacitance rated at 56 V for energy storage and decoupling in power rails and audio circuits.
• Snap-in Radial Can Package — Radial, can-type snap-in mounting for secure board installation and mechanical stability.
• Polarized Construction — Polar aluminum electrolytic design for DC filtering and smoothing applications.
• Operating Temperature Range — Specified from −40°C to +85°C to cover typical commercial and audio-environment temperature conditions.
• Endurance — Rated for 1000 h at 85°C under applied rated voltage, with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Ripple Current — Rated ripple current of 4.15 A at 120 Hz for handling AC ripple in power-supply and audio circuits.
• Tolerance — Capacitance tolerance of −20% to +20% (±20% typical at 120 Hz, 20°C).
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical size L: 5 × D: 3 cm suitable for space-conscious designs requiring higher capacitance.

Typical Applications

• Audio Equipment — Replacement of smaller standard capacitors to achieve measurable tone-quality improvement in amplifiers and audio power sections.
