LKG1K182MESBBK

The LKG1K182MESBBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, optimized for high‑grade audio equipment. It combines 1.8 mF (1800 μF) capacitance with an 80 V rated voltage in a radial, snap‑in can package suitable for robust power‑rail applications in audio systems.

Designed with audio performance in mind, this part delivers high capacitance, a specified tan δ of 0.25, and a ripple current rating of 2.85 A (120 Hz), while meeting RoHS requirements. It is specified for operation from −40 °C to +85 °C and endurance of 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 μF) nominal capacitance with an 80 V rated voltage and ±20% tolerance.
• Low Loss Characteristic — Specified tangent of loss angle (tan δ) of 0.25 (measured at 120 Hz, 20 °C), supporting stable performance in audio circuits.
• Ripple and Leakage — Ripple current rated at 2.85 A (120 Hz) and a measured leakage current figure provided for design margining (1130 μA).
• Package & Mounting — Radial, snap‑in can (snap‑in terminal) for secure chassis or PCB mounting and reliable mechanical retention.
• Size — Compact footprint: φ30 × 35 mm (L: 3.5 × D: 3 cm), tray packing.
• Thermal & Endurance — Operating range −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C.
• Regulatory — RoHS compliant.

Typical Applications

• High‑grade Audio Equipment — Bulk energy storage and smoothing in power supplies for amplifiers and audio electronics where fidelity is prioritized.
• Power Rail Decoupling — Local reservoir and decoupling on high‑voltage audio power rails to support transient demands.
