Overview of LKG2A122MESBAK – Aluminum Electrolytic Snap‑In Capacitor, 1200 µF, 100 V

The LKG2A122MESBAK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, configured for polarized power applications in audio equipment. It delivers 1.2 mF (1200 µF) capacitance at a 100 V rating in a compact snap‑in radial can (φ30 × 25L).

Designed for high‑grade audio use, the LKG series emphasizes fidelity‑oriented performance with robust ripple handling and endurance characteristics suitable for power supply smoothing, coupling/decoupling, and other audio power applications across an operating range of −40 °C to +85 °C.

Key Features

  • Capacitance & Voltage — 1.2 mF (1200 µF) rated at 100 V with ±20% capacitance tolerance (measured at 120 Hz, 20 °C).
  • Polarized Electrolytic Construction — Standard polarized design appropriate for DC power filtering and energy storage in audio power stages.
  • Ripple Current Handling — 2.2 A ripple current specified at 120 Hz, enabling effective smoothing under AC ripple loads.
  • Leakage Current — Product listing indicates a leakage current of 1030 µA; datasheet criteria specify leakage after 5 minutes at 20 °C not more than 3√(C·V) μA.
  • Endurance & Reliability — Rated for 1000 hours at 85 °C with specified post‑test limits: capacitance change within ±20%, tan δ up to 200% of initial spec, and leakage current within initial values.
  • Package & Mounting — Snap‑in radial can (φ30 × 25L) for secure board mounting and tray packing for handling and assembly.
  • Operating Temperature — −40 °C to +85 °C to cover typical environmental ranges encountered in audio electronics.
  • Regulatory — RoHS‑compliant per product data.

Typical Applications

  • High‑Grade Audio Power Supplies — Bulk energy storage and smoothing for amplifier rails to support steady supply under dynamic audio loads.
  • Audio Amplifiers — Decoupling and reservoir use to preserve fidelity and reduce ripple in preamp and power amp circuits.
  • Hi‑Fi Systems and Professional Audio — Component for designers prioritizing sound quality, stability, and long endurance in audio electronics.

Unique Advantages

  • High Voltage Capacity: 100 V rating supports higher‑voltage audio power circuits without resorting to multiple lower‑voltage caps in series.
  • Large Capacitance in a Compact Can: 1200 µF in a φ30 × 25L package provides significant energy storage while conserving board area.
  • Robust Ripple Handling: 2.2 A ripple current rating at 120 Hz reduces temperature rise and improves reliability under AC‑loaded conditions.
  • Endurance Proven to 85 °C: 1000‑hour endurance at 85 °C with defined post‑test limits for capacitance, tan δ, and leakage current supports predictable long‑term behavior.
  • Snap‑In Mounting: Radial snap‑in can design ensures secure mechanical retention for through‑hole assemblies and simplifies installation.
  • RoHS Compliant: Conforms to RoHS requirements as listed in the product data.
