LKG1H822MESCBK

The LKG1H822MESCBK is an aluminum electrolytic capacitor in a radial can snap‑in package designed for audio applications. It provides 8.2 mF (8200 µF) capacitance at a 50 V rating with a ±20% tolerance and a low loss angle to support high‑fidelity audio designs.

Part of Nichicon’s LKG series—optimized for high‑grade audio—the product targets HD audio and high‑tone‑quality equipment where low loss, stable operation across temperature, and robust ripple handling are required.

Key Features

• Capacitance & Voltage – 8.2 mF (8200 µF) rated at 50 V with ±20% tolerance for bulk energy storage and smoothing in audio circuits.
• Low Loss Angle – Specified tanδ of 0.3 (measurement frequency: 120 Hz at 20°C) to support low distortion and stable performance in audio signal environments.
• Package & Mounting – Radial, can snap‑in package (snap‑in terminal) for secure chassis or PCB mounting where a snap‑in form factor is required.
• Thermal & Endurance – Operating temperature range −40°C to +85°C with an endurance rating of 1000 hours at 85°C; after endurance test, capacitance change is within ±20%, tanδ remains ≤200% of initial spec, and leakage remains at or below initial specified value.
• Ripple Handling – Rated low‑frequency ripple current of 4.4 A at 120 Hz for continuous AC ripple environments common in audio power supplies.
• Leakage Current – Leakage current specification: after 5 minutes at rated voltage and 20°C, leakage is not more than 3√(C·V) µA (C in µF, V in V).
• Low‑temperature Stability – Impedance ratios specified for cold conditions: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 12 (measured at 120 Hz).
• Physical Dimensions – Body footprint approximately L: 4.5 × D: 3.5 cm with a seated height maximum of 1.772 inch; marked with gold color letters on a black sleeve.
• RoHS Compliance – Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio equipment – Designed to prioritize fidelity and tone quality in premium audio electronics.
• HD Audio systems – Matches the tone quality requirements specified for HD Audio equipment in the LKG series documentation.
• Audio power supply filtering – 8.2 mF capacitance and 4.4 A ripple rating at 120 Hz support smoothing and reservoir functions in audio power rails.

Unique Advantages

• Audio‑focused design – Part of the Nichicon LKG family developed for high‑grade audio, with series variants focused on tone quality.
• Low loss for cleaner sound – tanδ specified at 0.3 (120 Hz, 20°C) to minimize dissipation and help preserve audio fidelity.
• Robust ripple capacity – 4.4 A ripple current at 120 Hz enables handling of continuous AC ripple found in amplifier power supplies.
• Wide operating range – −40°C to +85°C rating supports stable operation across typical environmental conditions for audio equipment.
• Documented endurance – 1000 hours at 85°C endurance with clear post‑test criteria for capacitance, tanδ, and leakage current.
• Regulatory compliance – RoHS compliant to support restricted‑substance requirements.
