LAS2G181MELA30ZB

The LAS2G181MELA30ZB is a snap‑in terminal type aluminum electrolytic capacitor rated at 180 µF and 400 V, offered in a compact radial can (φ25×30 mm). It is designed for general‑purpose power applications requiring high voltage handling, elevated ripple performance and dependable endurance at elevated temperatures.

With a 105°C operating capability, a 2000‑hour endurance at rated conditions, and enhanced safety features for abnormal voltage conditions, this part addresses designs that need robust, long‑life bulk capacitance in a space‑efficient package.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance at a 400 V rating for high‑voltage energy storage and filtering.
• High‑Temperature Endurance — Rated for operation from −25°C to +105°C with a specified lifetime of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 900 mA (nominal); frequency‑dependent data include 950 mA at 120 Hz and 1.093 A at 10 kHz to support a range of switching and line frequencies.
• Leakage & Dissipation — Low leakage current (0.82 mA typical) and a maximum tan δ of 0.20 (120 Hz, 20°C) for predictable loss characteristics.
• Snap‑in Radial Can Package — Secure snap‑in terminals in a compact radial can format (φ25 × 30 mm) for reliable PCB mounting and mass production handling (tray packing).
• Improved Safety Design — Series features include a pressure relief vent and enhanced tolerance to abnormal voltages, intended to reduce hazardous failure modes under overvoltage conditions.
• RoHS Compliant — Meets RoHS directive requirements as specified in the product series documentation.

Typical Applications

• Equipment subject to voltage fluctuations — Designed for use in systems exposed to varying line conditions; improved safety features and endurance at 105°C help manage abnormal voltage events.
• Space‑constrained power systems — Smaller case size combined with high ripple current capability supports compact power assemblies where board space is limited.
• General‑purpose high‑voltage filtering — Polar aluminum electrolytic capacitor suitable for bulk smoothing and energy storage in general‑purpose 400 V circuits.

Unique Advantages

• Long thermal endurance — 2000 hours rated life at 105°C under rated ripple and DC bias provides predictable long‑term performance in hot environments.
• High ripple handling across frequencies — Frequency coefficients and rated ripple current values (e.g., 950 mA at 120 Hz, 1.093 A at 10 kHz) allow designers to size capacitors for both line‑frequency and high‑frequency applications.
• Compact, production‑friendly package — Snap‑in radial can and tray packing streamline PCB assembly and support mass production workflows.
• Safety‑focused construction — Pressure relief vent and tested abnormal voltage limits reduce the risk of dangerous failures under overvoltage conditions.
• Controlled electrical characteristics — Specified leakage current and tan δ provide tighter predictability for loss budgeting and thermal design.
• Regulatory compliance — RoHS compliance supports use in regulated markets and products.
