LKG1V123MESBAK

The LKG1V123MESBAK is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKG series, specified for high‑grade audio equipment. It delivers 12,000 µF of capacitance at a 35 V rating in a radial, can‑style snap‑in package designed for power supply and audio filtering applications.

This component is offered as a TYPE‑II (Gold Tune) grade from the LKG family, RoHS compliant, and characterized for operation from −40 °C to +85 °C with a rated endurance of 1,000 hours at 85 °C. Packaging is provided in tray format.

Key Features

• Capacitance & Tolerance — 12,000 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C), providing significant bulk energy storage for smoothing and decoupling in audio power rails.
• Rated Voltage — 35 V rated voltage suited for common audio amplifier and power‑supply rails.
• Audio‑oriented Grade — TYPE‑II (Gold Tune) designation within the LKG series, designed specifically for high‑grade audio equipment to prioritize sound quality characteristics.
• Package & Mounting — Radial can with snap‑in terminals for secure PCB mounting and robust mechanical retention in chassis and power modules; physical size approximately Ø30 mm × 40 mm length.
• Thermal & Lifetime — Operating temperature range −40 °C to +85 °C with endurance specified as 1,000 hours at 85 °C under rated voltage conditions.
• Electrical Performance — Specified low‑frequency ripple current of 3.3 A at 120 Hz; leakage current defined by the datasheet limit of not more than 3√(C·V) µA after 5 minutes at 20 °C.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Professional Audio Amplifiers — Bulk energy storage and smoothing for power supplies in high‑fidelity amplifier designs.
• High‑End Consumer Audio — Power rail decoupling and reservoir capacitance in premium stereo and home theater equipment.
• Audio Power Supplies — Filtering of low‑frequency ripple and transient support in regulated and unregulated audio power modules.

Unique Advantages

• Large Bulk Capacitance: 12,000 µF provides substantial stored energy for low‑frequency smoothing and improved supply stability in audio systems.
• Audio‑Focused Design: Part of the LKG series’ Gold Tune TYPE‑II grade, intended to prioritize tone quality for HD audio equipment.
• Robust Thermal Specification: Rated for continuous operation up to 85 °C with a 1,000‑hour endurance rating at that temperature, supporting sustained use in constrained thermal environments.
• Snap‑in Mechanical Retention: Radial can with snap‑in terminals simplifies board assembly and provides secure mounting for power and chassis installations.
• Defined Ripple & Leakage Limits: Specified low‑frequency ripple current (3.3 A at 120 Hz) and a datasheet leakage current limit provide verifiable electrical performance for design validation.
• RoHS Compliance: Meets RoHS directive requirements for restricting certain hazardous substances.
