LAS2W101MELA25ZB

The LAS2W101MELA25ZB is a Nichicon snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose high‑voltage applications. It delivers 100 µF at a 450 V rating in a compact φ25 × 25 mm can with snap‑in mounting and is produced for mass production with tray packing.

Engineered for demanding environments, the device is specified for operation from −25°C to 105°C, 2000 hours endurance at 105°C under rated ripple conditions, and includes safety features for abnormal voltage conditions.

Key Features

• Electrical Core — 100 µF capacitance with ±20% tolerance at 120 Hz, 20°C; polarized aluminum electrolytic construction.
• High Voltage Rating — Rated voltage 450 V suitable for high‑voltage filtering and energy storage applications.
• Low Loss — Tangent of loss angle (tan δ) 0.20 max at 120 Hz, 20°C to control dissipation in AC ripple conditions.
• Ripple Current Capability — 710 mA at 120 Hz (low frequency) and 816.5 mA at 10 kHz (high frequency) to support demanding ripple loads; frequency coefficient rises to 1.15 at 10 kHz or more.
• Leakage Current — Specified leakage current of 630 µA (measured conditions per product data).
• Endurance and Reliability — Rated for 2000 hours at 105°C with D.C. bias plus rated ripple current applied; meets post‑test limits for capacitance, tan δ and leakage current as specified.
• Safety Features — Pressure relief vent and improved safety performance designed to operate under abnormal voltage conditions without flame or dangerous dispersion.
• Mechanical & Mounting — Snap‑in radial can package (φ25 × 25L) for secure board mounting and simplified assembly; tray packing for production handling.
• Compliance — RoHS compliant as stated in product information.

Typical Applications

• Power supply filtering: High‑voltage smoothing and bulk storage in industrial and commercial power supplies using the 450 V rating and high ripple capability.
• Inverters and converters: DC link and energy buffering where high voltage endurance and 2000‑hour life at 105°C are required.
• Industrial equipment: General‑purpose high‑voltage filtering and decoupling in equipment that operates across −25°C to 105°C.

Unique Advantages

• High‑voltage endurance: 450 V rating combined with 2000 hours endurance at 105°C provides predictable life under rated ripple and temperature stress.
• Robust ripple handling: 710 mA (120 Hz) and 816.5 mA (10 kHz) ripple current specifications support higher AC stress without excessive heating.
• Compact snap‑in package: φ25 × 25L radial can with snap‑in terminals enables secure PCB mounting while conserving board area.
• Safety‑oriented design: Pressure relief vent and abnormal voltage protection reduce risk under overvoltage events.
• Production ready: Tray packing and mass production status simplify procurement and assembly planning.
• Standards compliance: RoHS compliance supports use in regulated product environments.
