LAS2W121MELB25ZB

The LAS2W121MELB25ZB is a snap-in terminal aluminum electrolytic capacitor rated at 450 V and 120 µF with ±20% tolerance. It is a polarized, radial can, snap-in package designed for general-purpose electronic equipment.

Engineered for elevated-temperature operation and voltage-fluctuating environments, this part offers 105 °C performance, extended endurance under rated ripple current, and built-in safety features to mitigate abnormal voltage conditions.

Key Features

• Electrical performance — Rated capacitance 120 µF at 450 V with ±20% tolerance and polarized construction for DC energy storage and filtering.
• High-temperature endurance — Rated for operation from -25 °C to +105 °C with a guaranteed endurance of 2000 hours at 105 °C when D.C. bias plus rated ripple current is applied.
• Ripple current capability — Rated ripple current: 770 mA at 120 Hz and 885.5 mA at 10 kHz; frequency coefficient rises to 1.15 at 10 kHz or higher, improving high-frequency ripple handling.
• Safety under abnormal voltage — Designed with improved safety features and a pressure relief vent that operates under abnormal conditions to avoid dangerous failure modes.
• Compact snap-in package — Radial can, snap-in mounting in a φ30 × 25L form factor (L: 2.5 cm × D: 3.0 cm) for chassis or PC-board assemblies; supplied in tray packing for mass production.
• Quality and identification — Marked in white on a black sleeve for clear identification; RoHS compliant.

Typical Applications

• Equipment in voltage-fluctuating areas — Suitable where supply voltages vary, providing rated endurance and safety performance under abnormal voltage conditions.
• General-purpose electronic equipment — Applicable to a wide range of general-purpose systems that require high-voltage DC capacitance in a snap-in package.
• High-temperature environments — Suited for applications that demand stable performance and long life at elevated ambient temperatures up to 105 °C.

Unique Advantages

• High voltage rating: 450 V rating enables use in higher-voltage DC circuits where elevated working voltage is required.
• Extended high-temperature life: 2000-hour endurance at 105 °C under rated ripple current delivers predictable lifetime in demanding thermal environments.
• Improved safety design: Pressure relief vent and series-level safety tests help reduce risk under abnormal overvoltage conditions.
• Strong ripple performance: Specified ripple current at both low and high frequencies plus a favorable frequency coefficient supports robust ripple handling across common operating frequencies.
• Space-efficient snap-in form: φ30 × 25L radial snap-in can provides a compact, assembly-friendly solution for chassis and board-level placement.
• Production-ready packaging: Tray packing and mass-production availability simplify procurement and assembly planning.
