LAS2G271MELB35ZB

The LAS2G271MELB35ZB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 270 µF capacitance at 400 V in a compact φ30×35L can, and is built for equipment exposed to fluctuating supply voltages.

Key value propositions include high ripple endurance at elevated temperature and enhanced safety performance for abnormal overvoltage conditions, making it suitable for designs requiring robust smoothing and filtering under demanding thermal and electrical stress.

Key Features

• Capacitance & Rated Voltage — 270 µF nominal capacitance rated for 400 VDC, with tolerance ±20% at 120 Hz, 20°C.
• High‑temperature endurance — Specified operating temperature range of −25°C to +105°C with endurance of 2000 hours at 105°C when subjected to rated DC bias plus rated ripple current.
• Ripple current capability — Rated ripple current of 1.3 A at 120 Hz and 1.495 A at 10 kHz (part‑level frequency data provided), with frequency coefficients available for design calculations.
• Snap‑in radial can package — Snap‑in terminal type in a compact radial can: L: 3.5 × D: 3.0 cm (φ30×35L) for secure PCB mounting and mechanical stability.
• Improved safety performance — Designed with safety features for abnormally excessive voltage; pressure relief vent operates under abnormal conditions without flame or hazardous dispersion.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power supplies — Bulk smoothing and filtering in power supply rails where 400 V ratings are required.
• Equipment in fluctuating‑voltage environments — Suited for systems exposed to supply voltage variation thanks to enhanced safety features and ripple endurance.
• High‑temperature power electronics — Components operating up to 105°C and requiring validated 2000‑hour ripple endurance.

Unique Advantages

• Validated 2000‑hour ripple endurance at 105°C: Provides predictable performance after extended high‑temperature ripple loading for greater design confidence.
• Concrete ripple current specifications: Published ripple current values at 120 Hz and 10 kHz allow accurate thermal and lifetime budgeting in power designs.
• Compact snap‑in form factor: φ30×35L radial can with snap‑in terminals for reliable PCB retention while minimizing board footprint.
• Safety‑oriented construction: Pressure relief vent and abnormal‑voltage protections reduce risk of hazardous failure modes under excessive voltage conditions.
• RoHS compliance: Meets relevant RoHS directives for use in regulated markets.
