LKG1K821MESZCK

The LKG1K821MESZCK is an aluminum electrolytic snap‑in capacitor from Nichicon's LKG series, designed for audio equipment where fidelity and stable power handling are required. It is a TYPE‑III (Super Through) grade component tailored for high‑tone quality applications and audio system power stages.

This snap‑in, radial can capacitor provides 820 µF capacitance at an 80 V rating in a compact φ22 × 40 mm package, delivering measured characteristics suitable for audio power supply filtering and related use cases.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20°C, matching common audio power supply requirements.
• Audio‑grade TYPE‑III — Part of the LKG series' TYPE‑III grade (CK code), specified for high tone quality; the series description identifies this grade for highest tone quality and adopts gold‑plated terminals in the family.
• Low‑frequency ripple handling — Rated low‑frequency ripple current of 2.45 A at 120 Hz, suitable for smoothing and decoupling in audio power applications.
• Electrical loss (tan δ) — Specified tangent of loss angle of 0.2 (tanδ) at 20°C, 120 Hz, enabling predictable frequency‑dependent behavior in audio circuits.
• Leakage current — Typical leakage current specified at 760 µA for end‑use consideration during biasing and shelf‑life planning.
• Package & Mounting — Snap‑in radial can with φ22 mm diameter and 40 mm length for secure chassis mounting and compact assembly; supplied in tray packing for handling.
• Temperature & Endurance — Operating range −40°C to +85°C with endurance specified as 1000 hours at 85°C, aligning with elevated‑temperature audio system requirements.
• RoHS Compliance — Compliant with RoHS directives as noted for the LKG series.

Typical Applications

• High‑fidelity audio amplifiers — Bulk filtering and power smoothing where stable capacitance and low loss are important to maintain audio performance.
• Professional audio equipment — Power supply decoupling and reservoir use in consoles, preamps, and studio electronics that prioritize tone quality.
• Audio power stages — Local energy storage and ripple attenuation for mid‑power amplifier modules and related circuits operating up to 80 V.

Unique Advantages

• Audio‑focused grade: TYPE‑III designation in the LKG family targets high‑tone quality, making this capacitor suitable where audio characteristics matter.
• High voltage capability: 80 V rating enables use in higher‑voltage audio power supplies and designs that require greater DC headroom.
• Strong ripple performance: 2.45 A low‑frequency ripple rating at 120 Hz supports effective smoothing in power transformer‑fed systems.
• Compact snap‑in format: φ22 × 40 mm radial can with snap‑in terminals provides a space‑efficient, mechanically robust mounting option for chassis or PCB assemblies.
• Predictable loss and leakage: Specified tanδ of 0.2 (120 Hz, 20°C) and leakage current of 760 µA allow accurate circuit modeling and bias planning.
• Temperature endurance: Rated for −40°C to +85°C with a 1000‑hour endurance at 85°C for stability under elevated operating temperatures.
