The LAR2G561MELC40 is an aluminum electrolytic, snap‑in terminal capacitor in a radial can package, offering 560 µF capacitance at a 400 V rated voltage. It is designed for general‑purpose use where high-voltage energy storage, ripple handling and elevated operating temperature capability are required.

Key design attributes include a 105°C permissible operating temperature, proven endurance under ripple and DC bias, and measures to reduce short incidence under overvoltage conditions. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 400 V rated voltage; capacitance tolerance ±20% at 120 Hz, 20°C.
• High‑temperature Endurance — Endurance demonstrated at 105°C with 2000 hours of rated ripple current application and DC bias, with capacitance change within ±20% after test.
• Ripple Current Performance — Rated ripple current of 1.9 A at 120 Hz and 2.717 A at 50 kHz, enabling reliable AC ripple handling in high‑voltage circuits.
• Safety under Overvoltage — Designed to reduce short incidence when exposed to overvoltage (rated voltage × 1.5); safety testing indicates a substantial portion of parts pass defined overvoltage conditions without short or flame.
• Leakage & Loss Characteristics — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ maximum 0.15 for 200–400 V at 120 Hz, 20°C.
• Package & Mounting — Radial, snap‑in can package (φ35 × 40 mm nominal length) for secure snap‑in mounting; physical size approximately L: 40 mm × D: 35 mm.
• Operating Range & Compliance — Rated for −25°C to +105°C operation and compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power electronics — Provides bulk energy storage and ripple current handling for a wide range of general‑purpose circuits requiring 400 V operation and elevated temperature tolerance.
• High‑voltage smoothing — Used where high DC voltage smoothing and capacitance stability at 105°C are required.
• Industrial equipment — Suitable for general‑purpose industrial power circuitry that benefits from snap‑in mounting and the part’s high ripple endurance.

Unique Advantages

• High‑voltage capability: 400 V rating supports designs that require elevated DC bus voltages without adding series components.
• Proven high‑temperature endurance: 2000 hours at 105°C under rated ripple current ensures predictable long‑term behavior in hot operating environments.
• Robust ripple handling: Explicit ripple current ratings at 120 Hz and 50 kHz enable designers to size capacitors confidently for expected AC stress.
• Improved safety under overvoltage: Design and testing reduce incidence of shorts when subjected to 1.5× rated voltage under limited current conditions.
• Snap‑in radial package: Snap‑in terminals simplify PCB mounting and mechanical retention in power assemblies.
• RoHS compliance: Meets RoHS directive requirements for restricted substances.
