LAS2W121MELA30ZB

The LAS2W121MELA30ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor rated 450V and 120µF (±20%), designed for general‑purpose power applications. It combines a compact radial can snap‑in package (φ25×30L, approximately 3.0×2.5 cm) with high‑temperature endurance to support demanding voltage‑fluctuating environments.

Engineered for reliability, this capacitor is specified for continuous operation up to 105°C and is intended for use where high ripple handling and robust safety features are required.

Key Features

• Electrical rating — 120 µF capacitance with a 450 V rated voltage and ±20% tolerance, providing energy storage for high‑voltage power rails.
• High‑temperature endurance — Specified for operation from −25°C to 105°C with an endurance rating of 2000 hours at 105°C under rated ripple conditions.
• Snap‑in radial package — Can‑type, snap‑in terminals for secure mounting in power assemblies; described size φ25×30L (L: 3 cm × D: 2.5 cm).
• Ripple current capability — Rated ripple currents of 760 mA at 120 Hz and 874 mA at 10 kHz, with frequency coefficients (400–450 V) of 0.88 at 50 Hz, 0.90 at 60 Hz, 1.00 at 120 Hz, 1.10 at 1 kHz and 1.15 at 10 kHz or above.
• Safety features — Includes a pressure relief vent designed to operate without producing flames, ignitions or dispersion of fragments under abnormal conditions.
• Polarized design — Polarized electrolytic construction for DC bus and smoothing applications.
• RoHS compliant — Manufactured to meet RoHS requirements.
• Production packaging — Supplied in tray packing suitable for mass production environments.

Typical Applications

• Power supplies — Bulk filtering and energy storage on high‑voltage rails to smooth DC and handle ripple currents.
• Industrial power equipment — Voltage stabilization and smoothing in equipment operating in areas with fluctuating supply voltage.
• Inverters and converters — DC link smoothing where high voltage rating and high ripple endurance are required.

Unique Advantages

• High‑voltage capability: 450 V rating enables use on elevated DC buses without series stacking.
• Designed for elevated temperatures: 105°C operation and 2000‑hour endurance at that temperature support long life in hot operating environments.
• Measured ripple performance: Published ripple current figures at 120 Hz and 10 kHz plus frequency coefficients allow precise thermal and life planning.
• Robust safety design: Pressure relief vent minimizes risk under abnormal voltage conditions without flame or fragmentation.
• Manufacturing ready: Tray packing and snap‑in terminals simplify assembly and secure PCB mounting for production lines.
• Regulatory compliance: RoHS compliance supports use in regions requiring restricted substances conformance.
