LASW6181MELC25

The LASW6181MELC25 from Nichicon is a snap‑in, aluminum electrolytic capacitor rated 180 µF at 420 V. Designed as a compact, radial can with snap‑in terminals, it targets general‑purpose power applications and equipment operating in environments with fluctuating supply voltages.

Key value is delivered through high ripple handling, extended endurance at elevated temperature, and built‑in safety features for abnormal overvoltage conditions, combined with RoHS compliance for regulated deployments.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance at a rated voltage of 420 V, with tolerance ±20% (measured at 120 Hz, 20°C).
• High Temperature Endurance — Rated for 2000 hours at 105°C when subjected to DC bias plus rated ripple current; capacitance remains within ±20% after endurance test.
• Ripple Current Performance — Rated ripple current of 900 mA at 120 Hz, 105°C, with a higher frequency coefficient available (1.035 A at 10 kHz listed for high‑frequency ripple performance).
• Safety Features — Improved safety design with a pressure relief vent that operates under abnormal excessive voltage without causing flames, ignition, or dispersion of case pieces.
• Electrical Quality — Low leakage current (specified 0.82 mA) and tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C for predictable loss characteristics.
• Temperature Range — Operating from −25°C to +105°C for use in a wide range of ambient conditions.
• Package & Mounting — Compact radial can, snap‑in terminal type, physical size approximately Ø35 × 25 mm for space‑constrained boards.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power equipment — Bulk filtering and energy storage in industrial and commercial electronics that require robust high‑voltage capacitors.
• Voltage‑fluctuation environments — Designed for equipment operating where input voltages may fluctuate, leveraging improved safety and endurance under ripple and DC bias.
• Power conversion modules — Suitable for DC link and smoothing roles where a 420 V, high‑ripple capacitor is required in a compact, snap‑in package.

Unique Advantages

• Extended high‑temperature life: 2000 hours at 105°C under rated conditions provides predictable longevity in hot operating environments.
• High ripple tolerance: 900 mA at 120 Hz (and 1.035 A at 10 kHz) supports effective filtering and energy handling in power circuits.
• Compact snap‑in form factor: Ø35 × 25 mm radial can with snap‑in terminals simplifies board mounting while minimizing enclosure footprint.
• Built‑in safety venting: Pressure relief design reduces risk during abnormal overvoltage events, improving system safety without hazardous effects.
• Measurable electrical stability: Low leakage (0.82 mA) and tan δ ≤ 0.20 at 120 Hz ensure consistent loss and leakage behavior for design predictability.
• RoHS compliance: Meets current RoHS requirements for restricted substances, easing regulatory acceptance in many markets.
