LKS1V123MESC

The LKS1V123MESC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, engineered for audio equipment and smaller-sized replacement applications. It provides polarized bulk capacitance in a radial, can-style snap-in package suitable for general-purpose power filtering and audio power supply smoothing.

Key electrical and reliability characteristics include 12 mF capacitance at a 35 V rating, a wide operating temperature range, and endurance validated at elevated temperature to support sustained operation in demanding environments.

Key Features

• Package & Mounting — Radial, can-style snap-in terminal design for secure PCB retention and straightforward assembly in through-hole layouts.
• Capacitance & Voltage — 12 mF (12,000 µF) nominal capacitance with a 35 V rated voltage and ±20% tolerance for bulk energy storage and smoothing.
• Ripple Handling — Rated ripple current of 3.25 A at 120 Hz to support power-supply decoupling and filtering under AC ripple conditions.
• Temperature Range — Operates from −40°C to +85°C, suitable for a wide range of electronic environments.
• Endurance — Specified lifetime of 1000 hours at 85°C with defined post-test limits for capacitance change, dissipation factor (tan δ) and leakage current.
• Leakage Current Specification — Leakage current limited to not more than 3√CV (μA) after five minutes’ application of rated voltage at 20°C, providing predictable leakage behavior.
• Audio-Focused Design — LKS series positioning targets audio equipment; replacement from smaller standard parts is noted to produce a tone-quality improvement.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power-supply smoothing and decoupling in amplifiers, speaker crossover networks, and other audio subsystems where improved tone quality is desired.
• Power Filtering in General-Purpose Electronics — Bulk energy storage and ripple suppression for supplies in consumer and industrial systems.
• Replacement / Upgrades — Direct replacement of smaller standard capacitors to increase bulk capacitance and influence system audio characteristics.

Unique Advantages
