LGC2H181MELA35

The LGC2H181MELA35 is a Nichicon LGC series snap‑in aluminum electrolytic capacitor providing 180 µF at a 500 V rating in a compact snap‑in can. It is designed for general‑purpose high‑voltage, long‑life applications that require stable capacitance over extended elevated‑temperature operation.

With a −40°C to 105°C operating range and a 5000‑hour endurance at 105°C, this part targets designs that require sustained high‑temperature reliability and effective ripple handling in a space‑efficient radial, snap‑in package.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 500 V rated voltage, suitable for high‑voltage smoothing and energy storage tasks.
• Long Life at Elevated Temperature — Endurance specified at 5000 hours at 105°C with defined limits for capacitance change and leakage current after test, supporting reliable long‑term operation.
• Wide Temperature Range — Rated for operation from −40°C to +105°C to cover harsh thermal environments.
• Snap‑in, Radial Can Package — Compact φ25 × 35 mm can with snap‑in terminals for secure board mounting and simplified assembly; tray packing for production handling.
• Ripple Current Performance — Low‑frequency ripple current of 1.2 A (120 Hz) and high‑frequency ripple current of 1.716 A (50 kHz), enabling effective ripple absorption across common power frequencies.
• Electrical Loss and Leakage — Tangent of loss angle (tan δ) 0.25 max (120 Hz, 20°C) and leakage current specified at 900 µA for this part, supporting predictable dissipation and leakage behavior.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• General‑purpose power filtering — Smoothing and decoupling in high‑voltage power rails where sustained high‑temperature performance and ripple handling are required.
• Industrial power electronics — Bulk capacitance and ripple management in industrial equipment operating at elevated temperatures.
• High‑voltage energy storage — Local energy reservoir for circuits that need 500 V-rated capacitance with long endurance.

Unique Advantages

• High‑voltage capability: 500 V rating enables use in higher‑voltage circuits without series stacking.
• Designed for extended high‑temperature duty: 5000 hours endurance at 105°C provides predictable long‑term capacitance and leakage behavior under continuous thermal stress.
• Compact snap‑in package: φ25 × 35 mm radial can with snap‑in terminals balances a smaller case footprint with robust board retention for production assembly.
• Predictable ripple handling: Specified ripple currents at 120 Hz and 50 kHz support effective filtering across low and high frequency ranges.
• Controlled electrical loss and leakage: Tan δ ≤ 0.25 and defined leakage current provide known dissipation and standby characteristics for reliable circuit design.
• RoHS compliance: Conforms to RoHS directives for environmental and regulatory requirements.
