The LKG1H821MESZCK is an aluminum electrolytic capacitor in Nichicon's LKG series, featuring a snap-in terminal radial can for secure board or chassis mounting. Engineered for audio use, this capacitor targets high‑fidelity audio equipment where stable filtering and reliable ripple handling are required.

Key electrical characteristics include 820 µF capacitance at 50 V rated voltage, a specified tan δ of 0.22 (measured conditions provided in the datasheet), and a ripple current rating of 1.4 A at 120 Hz. The device is compliant with RoHS requirements and is specified for operation from −40 °C to +85 °C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk energy storage in audio circuits.
• Audio-focused Design — Part of the LKG series developed specifically for audio equipment, prioritizing tone quality and high‑fidelity performance as described in the series documentation.
• Loss & Leakage Characteristics — Specified tan δ of 0.22 (measurement at 120 Hz, 20 °C) and leakage current listed as 600 µA, supporting predictable behavior in signal and power stages.
• Ripple Current Capability — Rated ripple current of 1.4 A at 120 Hz, enabling effective smoothing in power supply sections of audio equipment.
• Temperature & Endurance — Operating range from −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C.
• Package & Mounting — Radial, snap‑in can package (φ22 × 30 mm nominal) for secure snap‑in mounting in power assemblies and filter banks.
• Regulatory — RoHS compliant.

Typical Applications

• High‑grade audio equipment — Designed for use in systems where high tone quality and fidelity are priorities, including HD audio components.
• Audio power supply modules — Bulk smoothing and decoupling in amplifier and preamplifier power supplies, leveraging the 1.4 A ripple rating at 120 Hz.
• Chassis-mounted filter banks — Snap‑in radial can format enables robust mechanical attachment for multi‑capacitance filter assemblies.

Unique Advantages

• Audio-tuned construction — Part of the LKG family designed for audio use, offering characteristics intended to support high‑fidelity sound reproduction.
• Measurable loss performance — A specified tan δ value (0.22) gives designers a clear basis for predicting ESR‑related behavior in audio circuits.
• Robust ripple handling — 1.4 A ripple current at 120 Hz supports effective smoothing under typical audio power supply ripple conditions.
• Wide operating range and endurance — −40 °C to +85 °C operation with 1000 hours endurance at 85 °C provides predictable lifetime behavior in temperate and industrial environments.
• Secure snap‑in mounting — Radial, snap‑in can (φ22 × 30 mm) simplifies mechanical integration in assemblies and reduces the need for additional retention hardware.
• Regulatory compliance — RoHS compliance supports designs targeting markets requiring restricted‑substance conformity.
