LAS2W331MELC35ZB

The LAS2W331MELC35ZB is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for general‑purpose power applications. It delivers 330 µF at 450 V with a compact φ35 × 35 mm case footprint and snap‑in mounting for secure vertical installation.

Engineered for equipment exposed to fluctuating supply voltages, this part offers extended ripple‑current endurance at elevated temperature and enhanced safety measures against abnormally excessive voltage, making it suitable where robust smoothing and durability are required.

Key Features

• Electrical Performance: 330 µF nominal capacitance at 450 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High ripple‑current endurance: Rated to withstand application of rated ripple current for 2000 hours at 105°C; specified ripple current values include 1.4 A at 120 Hz and 1.61 A at 10 kHz.
• Thermal and lifetime characteristics: Wide operating range from −25°C to +105°C and endurance validated by 2000 hours at 105°C under rated ripple conditions.
• Compact, snap‑in package: Radial, can snap‑in package with dimensions L: 3.5 × D: 3.5 cm for space‑efficient power assemblies.
• Improved safety features: Designed with a pressure relief vent and enhanced safeguards to operate safely under abnormally excessive voltage conditions.
• Frequency response for ripple current: Frequency coefficient data provided (e.g., 1.00 at 120 Hz, 1.15 at 10 kHz) to support design planning across line and switching frequencies.
• Environmental compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power smoothing: Bulk filtering and energy storage in power supplies and assemblies requiring a 450 V electrolytic solution.
• Voltage‑fluctuating equipment: Smoothing and ripple handling in equipment operating in environments with variable or unstable supply voltages.
• High‑temperature installations: Power systems and modules exposed to elevated ambient temperatures where 105°C operation and 2000‑hour ripple endurance are required.

Unique Advantages

• Proven ripple endurance: 2000 hours of rated ripple‑current application at 105°C provides predictable long‑term performance under stress.
• Frequency‑aware ripple capability: Published ripple current values and frequency coefficients let designers scale ripple expectations from 50 Hz up to 10 kHz and above.
• Space‑efficient form factor: φ35 × 35 mm case delivers high capacitance and voltage in a reduced footprint compared with earlier series, enabling denser power assemblies.
• Enhanced safety design: Pressure relief vent and construction targeted at safe operation under abnormal voltage events reduce risk of hazardous failure modes.
• RoHS compliance: Meets applicable RoHS directives for restricted substances, supporting regulatory needs for many electronics products.
