Overview of LKG2A821MESBCK – Aluminum Electrolytic Snap‑In Capacitor, 820 µF, 100 V

The LKG2A821MESBCK is a Nichicon LKG series aluminum electrolytic capacitor in a snap‑in terminal (lug) radial can package, engineered for audio equipment. With a rated capacitance of 820 µF at 100 V and a polarized design, it targets high‑tone quality requirements in high‑grade and HD audio systems.

Designed with audio performance and service reliability in mind, this snap‑in capacitor combines a compact φ30 × 30 mm form factor with specified ripple handling and a defined endurance profile for use in demanding audio applications.

Key Features

  • Capacitance & Voltage — 820 µF nominal capacitance with a 100 V rated voltage; capacitance tolerance ±20% (120 Hz, 20°C).
  • Audio‑Focused Design — Part of the LKG series developed "for audio use" with emphasis on high fidelity and high tone quality for HD audio equipment.
  • Package & Mounting — Snap‑in (lug) radial can package in φ30 × 30 mm dimensions for secure board mounting and mechanically robust installation.
  • Operating Temperature Range — Specified for −40°C to +85°C operation, suitable for typical audio equipment environmental ranges.
  • Endurance — Rated for 1000 hours at 85°C with defined limits for capacitance change, tan δ, and leakage current after the endurance test.
  • Ripple and Leakage Characteristics — Rated ripple current 3 A at 120 Hz; leakage current specification after 5 minutes at 20°C is not more than 3√CV (μA), where C is μF and V is volts.
  • Polarized Electrolytic — Polar type capacitor appropriate for DC applications where polarized electrolytics are required.
  • RoHS Compliant — Conforms to RoHS requirements (2011/65/EU, (EU)2015/863) as stated in the series documentation.
  • Low‑Temperature Stability — Impedance characteristics defined for low temperatures: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 12 (measurement at 120 Hz).

Typical Applications

  • High‑Fidelity Audio Equipment — Suited for use in high‑grade audio systems and HD audio equipment where tone quality and audio fidelity are priorities.
  • Professional Audio Components — Applicable to studio gear and consumer hi‑fi components requiring reliable polarized capacitors in power and signal circuits.
  • Audio Power Modules — Used in audio power stages and modules where specified ripple current handling and voltage rating are required.

Unique Advantages

  • Audio‑First Engineering — Part of the LKG family specifically developed to prioritize high fidelity and tone quality for audio applications.
  • High Voltage Capability — 100 V rating provides headroom for audio circuits that require higher DC voltages without changing capacitor topology.
  • Robust Ripple Handling — 3 A ripple current rating (120 Hz) supports stable operation under typical audio power conditions.
  • Defined Endurance Profile — 1000 hours at 85°C specification gives clear expectations for long‑term performance under elevated temperature stress.
  • Reliable Low‑Temperature Performance — Specified impedance ratios at −25°C and −40°C help predict behavior in colder operating environments.
  • RoHS Compliance — Meets applicable RoHS directives for material and environmental compliance.
