LKG1H821MESBCK

The LKG1H821MESBCK is a snap-in aluminum electrolytic capacitor engineered for audio applications, delivering 820 µF at 50 V in a φ30 × 20 mm can. It is part of Nichicon’s LKG series developed for high-grade and HD audio equipment where tonal quality is prioritized.

This capacitor combines audio-focused construction details — including a low-loss characteristic (tan δ = 0.22) and gold-plated terminal technology described for the series — with practical assembly features such as a snap-in radial can package and a wide operating temperature range of −40 °C to +85 °C.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 50 V for energy storage and bulk decoupling in audio circuits.
• Audio-grade construction: Designed for high-grade audio and HD audio equipment with a focus on fidelity; the series documentation highlights low drag from gold-plated terminals to support high tone quality.
• Loss characteristic (tan δ): Specified tan δ = 0.22 (measured at 120 Hz, 20 °C) to indicate the capacitor’s loss behavior relevant to audio performance.
• Package & Mounting: Snap-in radial can (φ30 × 20 mm) for secure chassis mounting and stable mechanical retention.
• Temperature & Endurance: Rated for −40 °C to +85 °C operation with an endurance specification of 1000 hours at 85 °C.
• Leakage current specification: Leakage after 5 minutes at 20 °C is limited per the series formula (not more than 3√CV µA), providing a defined electrical leakage performance criterion.
• Ripple current: Specified low-frequency ripple current of 1.35 A at 120 Hz, relevant for audio power applications at mains-related frequencies.
• RoHS compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio equipment: Suitable for use in systems where fidelity and tonal quality are priorities, including high-end audio components.
• HD audio systems: Designed to meet the sound-quality expectations of HD audio devices as described for the LKG series.
• Professional audio assemblies: Mechanical snap-in mounting and a robust endurance rating make it appropriate for pro-audio chassis where reliable retention and long-term stability are required.

Unique Advantages

• Audio-focused specification: Series-level design and materials aim to address tonal quality needs in high‑fidelity audio applications.
• Defined electrical limits: Leakage current limited by the 3√CV rule and a specified tan δ give engineers measurable, verifiable performance parameters.
• Robust mechanical mounting: Snap-in radial can format supports secure installation in equipment chassis and panels.
• Operational durability: Endurance rating of 1000 hours at 85 °C provides a clear lifetime expectation under rated conditions.
• RoHS compliance: Meets current RoHS directive requirements for materials compliance.
