LAQ2P271MELC20ZB

The LAQ2P271MELC20ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, offering 270 µF capacitance at a 220 V rating in a compact φ35 × 20 mm can. It is a polarized, radial snap‑in device intended for general‑purpose power electronics where stable filtering and energy storage are required.

Designed for equipment operating across a wide temperature range and environments with voltage fluctuation, this part combines high ripple handling, a controlled dissipation factor, and a 2000‑hour endurance at elevated temperature for reliable mid‑term operation in industrial and commercial systems.

Key Features

• Capacitance & Tolerance — 270 µF nominal with ±20% tolerance at 120 Hz, 20°C for predictable filtering and decoupling performance.
• Rated Voltage — 220 V DC rating suitable for higher‑voltage power supply rails and commercial power electronic assemblies.
• Ripple Current Handling — 1.0 A at 120 Hz (low frequency) and 1.2 A at 10 kHz (high frequency) to support AC ripple and switching noise in power converters.
• Dissipation Factor — tan δ ≤ 0.20 at 20°C, 120 Hz, enabling controlled losses in filtering applications.
• Leakage Current — Specified leakage current of 730 µA after rated voltage application for predictable standby and bias behavior.
• Temperature & Endurance — Operating range −25°C to +105°C with 2000 hours endurance at 105°C under rated ripple and DC bias.
• Mechanical & Mounting — Snap‑in radial can package (φ35 × 20 mm) for secure board mounting and high vibration tolerance; supplied in tray packing for production lines.
• Safety & Series Traits — LAQ series includes safety features for abnormal voltage conditions and a pressure relief vent mechanism as specified in the series documentation; the series is noted as RoHS‑compliant in the manufacturer datasheet.

Typical Applications

• Industrial Power Supplies — Bulk filtering and ripple smoothing on 220 V DC rails and mid‑voltage supplies where extended ripple endurance is required.
• Control & Automation Equipment — Energy storage and decoupling in motor drives, PLC power modules, and control panels exposed to fluctuating mains conditions.
• Stationary Power Systems — Support for UPS, power distribution modules, and standby power circuits requiring long life at elevated temperatures.

Unique Advantages

• High ripple capability: Specified ripple current at both low (1.0 A @120 Hz) and high (1.2 A @10 kHz) frequencies allows the capacitor to handle both mains ripple and switching noise.
• Compact snap‑in package: φ35 × 20 mm radial can with snap‑in terminals provides a secure board mount while minimizing occupied board area for higher density assemblies.
• Extended endurance at 105°C: 2000‑hour rated life under specified DC bias and ripple current supports reliable operation in elevated temperature enclosures.
• Controlled dissipation and leakage: Low tan δ (≤0.20) and a defined leakage current (730 µA) give predictable thermal and quiescent behavior in power designs.
• Designed for voltage‑fluctuating environments: Series features include improved safety for abnormal voltage conditions and a pressure relief vent mechanism, supporting robustness in variable mains conditions.
• Production ready: Supplied in tray packing and listed as mass production, easing supply chain integration for volume assemblies.
