LKG2A821MESBBK

The LKG2A821MESBBK from Nichicon is a snap‑in aluminum electrolytic capacitor engineered for high‑grade audio equipment. It is part of the LKG series and the TYPE‑II (BK) grade, offering a balance of tonal quality and broad applicability in audio designs.

With 820 µF of capacitance at a 100 V rating in a compact φ30 × 25 mm can, this snap‑in capacitor supplies reservoir and filtering performance for audio power rails while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 100 V, tolerance ±20% (measured at 120 Hz, 20°C).
• Audio‑Oriented Grade — TYPE‑II (BK) grade from the LKG series designed to prioritize sound quality for high‑grade and HD audio equipment.
• Power Handling — Low‑frequency ripple current of 2.35 A (120 Hz) for effective smoothing and decoupling on audio power rails; specified leakage current of 850 µA.
• Reliability & Lifetime — Endurance rating of 1000 hours at 85°C; operating temperature range −40°C to +85°C for stable performance under elevated ambient conditions.
• Package & Mounting — Snap‑in terminal, radial can package in a φ30 mm diameter and 25 mm length form factor; supplied in tray packaging for board‑level handling and assembly.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Marked with gold‑color lettering on a black sleeve for clear grade and polarity identification.

Typical Applications

• High‑fidelity audio amplifiers — Reservoir and smoothing capacitor on power rails to support stable supply voltage and clean audio performance.
• HD audio equipment — Designed to meet tone quality needs in high‑grade audio systems where sound fidelity is a priority.
• Audio power supplies — Filter and decoupling duties in power supply sections of mixers, preamplifiers, and DAC front‑ends.

Unique Advantages

• Balanced audio tuning: TYPE‑II grade construction targets a practical balance of tonal quality suitable for a wide range of high‑grade audio applications.
• High voltage capability: 100 V rating provides headroom for higher‑voltage audio power rails and ruggedness against supply transients.
• Compact, serviceable package: 820 µF in a φ30 × 25 mm snap‑in can delivers substantial capacitance in a small footprint for efficient board layout.
• Robust ripple handling: 2.35 A ripple current (120 Hz) supports effective filtering under typical audio power conditions.
• Designed for durability: 1000 hours at 85°C endurance rating and −40°C to +85°C operating range support sustained performance in demanding environments.
• Regulatory compliance: RoHS conformity reduces material compliance overhead for commercial audio products.
