LKS1E123MESC

The LKS1E123MESC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose electronic applications. It delivers high bulk capacitance in a compact radial can with snap-in mounting for PCB assemblies.

Key value drivers include substantial capacitance (12,000 μF) at a 25 V rating, RoHS compliance, and an endurance profile defined for operation between −40 °C and +85 °C with rated-life confirmation (1,000 hours at 85 °C).

Key Features

• Capacitance and Tolerance — 12,000 μF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C for significant bulk energy storage.
• Voltage & Polarization — Rated at 25 V and polarized, appropriate for DC power reservoir applications where polarity is defined.
• Package & Mounting — Snap-in radial can package for secure board insertion and mechanical stability; package size 35 × 25 mm (diameter × length).
• Operating Range & Endurance — Specified operating temperature range of −40 °C to +85 °C with an endurance test of 1,000 hours at 85 °C under rated voltage.
• Ripple Performance — Rated ripple current of 2.65 A at 120 Hz for this size, supporting AC ripple handling in relevant circuits.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Intended for use in audio systems where replacing smaller standard capacitors can contribute to an audible tone-quality improvement.
• General-Purpose Electronic Equipment — Suitable for general-purpose PCB applications that require bulk capacitance with snap-in mounting.
• Replacement/Upgrades — Designed as a smaller-sized, higher-capacitance alternative to standard small capacitors, providing designers a drop-in upgrade option where improved audio characteristics are desired.

Unique Advantages

• Large Bulk Capacitance: 12,000 μF at 25 V provides substantial energy storage for power supply decoupling and reservoir needs.
• Designed for Audio Improvements: Specified as “for audio equipment” with a stated effect on tone quality when used as a replacement for smaller standard parts.
• Compact Snap-In Can: Radial snap-in package (35 × 25 mm) offers high capacitance density while supporting reliable mechanical mounting to PCBs.
• Defined Ripple Capability: Rated ripple current of 2.65 A at 120 Hz for the 12,000 μF size supports handling of AC ripple in relevant circuit topologies.
• Temperature & Endurance Specification: Operates from −40 °C to +85 °C with endurance tested to 1,000 hours at 85 °C, enabling predictable long-term performance within those conditions.
• RoHS Compliant: Conforms to modern RoHS requirements for regulatory compliance.
