Overview of LKG2A821MESYBK – Snap‑In Aluminum Electrolytic Capacitor, 820 µF / 100 V

The LKG2A821MESYBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LKG series, specified at 820 µF and 100 V. It is part of the LKG audio‑focused family, designed for use in high‑grade audio equipment and HD audio applications where stable bulk capacitance and electrical headroom are required.

Built for PCB snap‑in mounting in a radial can package, this capacitor pairs a large capacitance with 2.4 A ripple handling and a qualified endurance of 1000 hours at 85°C, offering dependable smoothing and energy storage in audio power stages and related circuits.

Key Features

  • Capacitance & Voltage — 820 µF nominal capacitance at a rated voltage of 100 V, with ±20% tolerance (measured at 120 Hz, 20°C).
  • Audio‑Oriented Design — Part of the LKG series engineered for audio equipment; this part number corresponds to the TYPE‑II (Gold Tune) grade targeting center‑grade audio performance within the series.
  • Power Handling — Rated ripple current of 2.4 A at 120 Hz to support power supply smoothing and decoupling in audio power stages.
  • Package & Mounting — Radial can with snap‑in terminals for secure board retention and straightforward assembly in through‑hole layouts (φ20 × 45 mm body dimensions).
  • Operating Range & Endurance — Specified operating temperature range of −40°C to +85°C and endurance of 1000 hours at 85°C with rated voltage applied.
  • Leakage Current — Product listing indicates leakage current of 850 µA; series specification states leakage after 5 minutes at 20°C is not more than 3√(C·V) μA (where C = µF, V = V).
  • RoHS Compliant — Conforms to RoHS directive requirements as noted for the LKG series.

Typical Applications

  • High‑Grade Audio Amplifiers — Bulk energy storage and power smoothing for amplifier power rails to support clean, stable supply under dynamic audio loads.
  • Professional and Consumer Hi‑Fi Equipment — Used in power supply filters and reservoir stages where audio‑oriented capacitor characteristics are desired.
  • Audio Power Supplies — Provides ripple handling and voltage headroom for regulator inputs and output filtering in audio systems.

Unique Advantages

  • Audio‑tuned grade (TYPE‑II) — Specified within the LKG family as the TYPE‑II Gold Tune grade, offering the series' center‑grade balance for audio performance.
  • High voltage capability — 100 V rating provides electrical headroom for higher‑voltage power rails without increasing footprint.
  • Robust ripple capacity — 2.4 A ripple current rating at 120 Hz supports continuous filtering duties in audio power supplies.
  • Snap‑in mounting — Radial, snap‑in can simplifies board placement and provides secure mechanical retention for through‑hole assemblies.
  • Designed endurance — 1000 hours at 85°C with rated voltage applied gives a defined reliability baseline for thermal and electrical stress conditions.
  • Regulatory compliance — RoHS compliance supports deployment in products targeting restricted‑substance requirements.

Why Choose LKG2A821MESYBK?

LKG2A821MESYBK is positioned for designers of audio and high‑fidelity equipment who need substantial bulk capacitance, high voltage rating and reliable ripple handling in a snap‑in, through‑hole form factor. Its specification envelope — 820 µF at 100 V, 2.4 A ripple current, −40°C to +85°C operating range and 1000 h endurance at 85°C — delivers a clear, verifiable foundation for power supply and smoothing applications in audio systems.

As part of Nichicon’s LKG series, this part benefits from series‑level audio orientation and documented electrical characteristics, making it suitable for engineers seeking documented performance and predictable lifecycle behavior in audio power designs.
