LAS2W820MELA25ZB

The LAS2W820MELA25ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose electronic equipment. It combines a compact radial can snap‑in package with 450 V rating and 82 µF capacitance for applications that require high voltage handling in a small footprint.

Engineered for elevated operating temperatures and voltage fluctuation resilience, this component delivers specified ripple‑current endurance at up to 105 °C and includes safety features for abnormal voltage conditions, making it well suited to power assemblies and equipment operating in variable supply environments.

Key Features

• Capacitance & Tolerance — 82 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C, providing predictable filtering and bulk storage.
• High Voltage Rating — Rated for 450 VDC operation for use in higher‑voltage power circuits and assemblies.
• High‑Temperature Endurance — Rated for operation from −25 °C to +105 °C and qualified for 2000 hours at 105 °C under rated ripple current and DC bias.
• Snap‑in Radial Can Package — Snap‑in terminal mounting in a compact φ25 × 25 mm case (25 × 25 mm) for secure chassis or power‑supply board installation.
• Ripple Current Performance — Rated ripple current 610 mA at 120 Hz and 701.5 mA at 10 kHz, with frequency coefficients provided for other operating frequencies.
• Improved Abnormal‑Voltage Safety — Incorporates a pressure relief vent and meets the series' abnormal‑voltage test conditions for the 450 V class (applicable limited‑current and test voltages for C < 100 µF).
• RoHS Compliant — Conforms to RoHS directive requirements.
• Clear Marking — Printed with white letters on a black sleeve for easy identification.

Typical Applications

• General‑purpose electronic equipment — Bulk energy storage and filtering where a 450 V rated electrolytic is required and snap‑in mounting is preferred.
• Equipment in fluctuating voltage environments — Designed with improved safety measures and endurance to tolerate supply variability and abnormal voltage events.
• Chassis and power assembly installations — Snap‑in radial can package enables secure mounting in power supplies and industrial assemblies requiring robust mechanical retention.

Unique Advantages

• High‑voltage capability: 450 V rating supports higher DC bus voltages without up‑rating components elsewhere in the design.
• Compact footprint: φ25 × 25 mm case provides a smaller case size while maintaining required capacitance and voltage handling.
• Long high‑temperature life: Qualified for 2000 hours at 105 °C under rated ripple and DC bias, supporting reliable operation in hot environments.
• Robust ripple handling: Specified ripple currents at 120 Hz and 10 kHz help ensure stable performance across common power frequencies.
• Enhanced safety for abnormal voltage: Pressure relief vent and series abnormal‑voltage testing reduce risk during overvoltage events.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for assemblies.
