LKG1C123MESZAK

The LKG1C123MESZAK is an aluminum electrolytic capacitor in a snap‑in terminal (radial can) package, engineered for audio applications where high fidelity sound quality is a priority. It is part of Nichicon's LKG series and is designed specifically for use in high‑grade and HD audio equipment.

Key electrical and reliability attributes include 12 mF nominal capacitance at 16 V rated voltage, polarized construction, an operating temperature range of −40 °C to 85 °C, and an endurance rating of 1000 hours at 85 °C. The part is RoHS compliant.

Key Features

• Electrical Capacity — 12 mF nominal capacitance with a tolerance of ±20% (specified at 120 Hz, 20 °C), suitable where substantial bulk capacitance is required.
• Rated Voltage — 16 V rated voltage for low‑voltage audio system designs.
• Polarized Aluminum Electrolytic — Polar construction appropriate for conventional audio power and filter topologies.
• Snap‑in Radial Can Package — Snap‑in mounting type and radial can package provide secure board attachment for through‑chassis or chassis‑mounted audio assemblies; physical size is L: 3.5 × D: 2.2 cm.
• Thermal and Long‑Term Reliability — Operating range from −40 °C to 85 °C and endurance rated to 1000 hours at 85 °C, with specified limits for capacitance change, tan δ, and leakage after endurance stress.
• Ripple Current Capability — Rated ripple current of 2.2 A at 120 Hz for handling low‑frequency ripple common in audio power supplies.
• Leakage Current Specification — Leakage current limit defined by the datasheet formula: after 5 minutes at rated voltage and 20 °C, leakage current is not more than 3√CV (µA), providing a verifiable leakage performance target.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio equipment — Designed to prioritize high fidelity sound quality in premium consumer and professional audio systems.
• HD Audio systems — Specified to meet the high tone quality needs for HD Audio equipment.
• Audio system power stages and filtering — Snap‑in aluminum electrolytic construction suited to bulk filtering and decoupling roles within audio power designs.

Unique Advantages

• Audio‑focused design: The LKG series is explicitly developed for audio use and prioritizes tone quality and fidelity for high‑grade and HD audio systems.
• Robust ripple handling: 2.2 A ripple current rating at 120 Hz supports low‑frequency ripple duties encountered in audio power supplies.
• Wide operating range with proven endurance: −40 °C to 85 °C operating range and 1000 hours endurance at 85 °C provide predictable performance over time under specified conditions.
• Secure mechanical mounting: Snap‑in terminal and radial can package offer secure installation for chassis or board mounting in audio assemblies.
• Measurable leakage limits: Leakage current governed by the datasheet formula (3√CV) gives a clear, testable acceptance criterion after initial voltage application.
• RoHS compliance: Meets current RoHS requirements, supporting regulatory needs for commercial audio products.
