LKG1H222MESZAK

The LKG1H222MESZAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, engineered for high‑grade audio equipment and HD audio systems. It delivers 2200 µF at 50 V with a low loss characteristic (tan δ 0.3) in a compact radial can (22 mm diameter × 25 mm length), optimized for fidelity‑focused audio applications.

Designed for audio use, this component combines high bulk capacitance, low tangent of loss angle, and a snap‑in package to simplify installation in power and signal circuits where sound quality and reliable operation over the specified temperature range are important.

Key Features

• Capacitance & Rated Voltage: 2200 µF nominal capacitance rated for 50 V, with ±20% tolerance at 120 Hz, 20°C.
• Low Loss Performance: Specified tan δ = 0.3 (measurement frequency: 120 Hz at 20°C) to support low‑loss audio signal and power handling.
• Audio‑Focused Design: Series purpose-built for high‑grade audio equipment and HD audio—prioritizes fidelity and tonal quality for audio system designers.
• Package & Mounting: Snap‑in terminal, radial can package that provides secure board mounting and compact footprint (L: 2.5 cm × D: 2.2 cm).
• Operational Range & Endurance: Rated for operation from −40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage.
• Leakage & Reliability: Leakage current specification follows series guideline (≤ 3√(C·V) µA after 5 minutes at 20°C), supporting predictable long‑term performance.
• Ripple Current Capability: 1.85 A at 120 Hz, suitable for audio power supply smoothing and decoupling roles within its rated conditions.
• RoHS Compliance & Aesthetic Marking: Compliant with RoHS (2011/65/EU,(EU)2015/863); marked with gold‑color letters on a black sleeve for visual identification.

Typical Applications

• High‑grade audio equipment: Intended for use in fidelity‑focused audio systems where low loss and stable bulk capacitance contribute to tonal quality.
• HD Audio systems: Matches the sound‑quality requirements of HD audio gear by combining low tan δ and substantial capacitance in a compact package.
• Audio power filtering: Suitable for filtering and smoothing in audio power circuits within the specified ripple and temperature limits.

Unique Advantages

• Audio‑first specification: Designed specifically for high‑grade and HD audio applications to address fidelity considerations in capacitor selection.
• Compact, serviceable form factor: 22 mm diameter × 25 mm length snap‑in can provides high capacitance in a space‑efficient radial package for chassis and board installations.
• Low tangent of loss angle: tan δ = 0.3 (120 Hz, 20°C) helps maintain low loss in signal and power paths critical to audio performance.
• Predictable ageing and endurance: Endurance validated to 1000 hours at 85°C under rated voltage with defined limits for capacitance change, tan δ, and leakage current.
• Measured low‑temperature stability: Series impedance limits at low temperatures (Z ratios defined for −25°C and −40°C vs +20°C) support performance across cold conditions.
• Regulatory compliance and identification: RoHS compliant and clearly marked with gold lettering on a black sleeve for easy part recognition.
