LAR2E271MELZ25

The LAR2E271MELZ25 is a Nichicon LAR series snap‑in terminal aluminum electrolytic capacitor specified for general‑purpose power applications. It provides 270 µF capacitance at a 250 V rating in a radial can with snap‑in mounting for secure board installation.

Designed for high‑temperature operation and robust ripple handling, this capacitor offers endurance at elevated temperatures and tolerance against overvoltage conditions, making it suitable for demanding industrial and commercial power circuits where stable DC smoothing and energy buffering are required.

Key Features

• Core Construction – Snap‑in Terminal: Radial can with snap‑in mounting provides a secure mechanical connection for high‑current and power assemblies.
• Capacitance & Voltage: 270 µF rated at 250 V with ±20% capacitance tolerance at 120 Hz, 20°C, suitable for DC‑link and bulk smoothing duties.
• High‑Temperature Endurance: Operating temperature range −40°C to +105°C with endurance specified as 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability: Rated ripple current of 1.1 A at 120 Hz and 1.65 A at 50 kHz, supporting a range of power‑frequency and switching applications.
• Overvoltage Safety Performance: Designed to reduce short incidence when exposed to 1.5× rated voltage; safety testing indicates normal pressure relief behavior under limited overvoltage conditions.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863), meeting current environmental substance requirements.

Typical Applications

• Power supply filtering: Bulk smoothing and decoupling in AC/DC and DC/DC power supplies where 250 V rating and 270 µF capacitance are required.
• Industrial power equipment: Energy buffering and ripple suppression in industrial converters and control systems that operate up to 105°C.
• Power modules and DC links: DC‑link smoothing for power assemblies that benefit from snap‑in mounting and specified ripple current capability.

Unique Advantages

• Stable performance at elevated temperatures: 2000‑hour endurance at 105°C under rated ripple current provides predictable long‑term behavior in hot environments.
• Robust ripple handling across frequencies: Specified ripple current values at 120 Hz and 50 kHz support both line‑frequency and higher‑frequency switching applications.
• Secure snap‑in mounting: Radial, can‑style snap‑in package simplifies board retention and mechanical stability in power assemblies.
• Reduced short incidence under overvoltage: The LAR series design includes measures to reduce shorting when subjected to 1.5× rated voltage, improving safety margins in fault conditions.
• Regulatory compliance: RoHS conformity supports environmentally regulated product designs.
