LAR2G271MELC25

The LAR2G271MELC25 is a Nichicon LAR series aluminum electrolytic capacitor in a snap‑in, radial can package. It provides 270 µF of bulk capacitance at a 400 V rating with polarized terminals designed for secure chassis or board mounting.

Engineered for general‑purpose power applications, this capacitor offers high‑voltage bulk storage and sustained ripple handling at elevated temperatures, supporting designs that require reliable long‑term endurance under load.

Key Features

• Rated Capacitance & Voltage — 270 µF nominal capacitance at 400 V rated voltage, with ±20% tolerance.
• High‑temperature Endurance — Specified to withstand 2000 hours of rated ripple current at 105°C, demonstrating sustained performance under elevated operating temperatures.
• Snap‑in Radial Can Package — Snap‑in terminal type in a φ35 × 25 mm can for secure mechanical mounting and easy assembly into power modules or chassis.
• Ripple Current Performance — Rated ripple current values include 1.22 A at 120 Hz and 1.745 A at 50 kHz; frequency coefficients for 400/450 V parts enable predictable ripple capability across a wide frequency range.
• Permissible Overvoltage Safety — Designed with a reduction of short incidence when overvoltage (rated voltage × 1.5) is applied; safety testing shows more than 60% passing under controlled overvoltage conditions with limited current.
• Operating Temperature Range — Specified for −25°C to +105°C operation for the 400 V/450 V variants.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Bulk Capacitor — Provides high‑voltage energy storage and smoothing for general‑purpose power supply circuits.
• Industrial Power Modules — Suited for cabinet or chassis mounting where a snap‑in radial can is preferred for secure mechanical attachment.
• High‑frequency Ripple Management — Supports ripple current at both low and high frequencies with documented ripple ratings and frequency coefficients for predictable performance.

Unique Advantages

• Proven High‑temperature Reliability: 2000‑hour endurance at 105°C under rated ripple current ensures predictable lifetime behavior in hot operating environments.
• High‑voltage Capability: 400 V rating delivers substantial bulk capacitance for higher‑voltage power systems without up‑rating components.
• Mechanical Stability: Snap‑in terminal design provides robust board or chassis retention, reducing assembly time and improving mechanical reliability.
• Frequency‑aware Ripple Performance: Published ripple current values and frequency coefficients let engineers size capacitors confidently across application frequencies.
• Safety‑oriented Design: Series characteristics include reduced incidence of shorting under 1.5× rated overvoltage with limited current, assisting safer failure modes.
• Regulatory Alignment: RoHS compliance supports deployment in regions and products requiring restricted substance conformity.
