LASW6181MELC25ZB

The LASW6181MELC25ZB is a 180 µF, 420 V polarized aluminum electrolytic capacitor in a snap‑in terminal, radial can package (φ35 × 25 mm). It is designed as a compact, high‑performance smoothing and energy storage component for general‑purpose electronic equipment, especially in systems operating in voltage‑fluctuating environments.

Key value propositions include higher ripple‑current capability and smaller case size compared with the LAQ series, robust endurance at elevated temperature (2000 hours at 105°C with rated ripple current), and improved safety features for abnormally excessive voltage. The part is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 180 µF rated capacitance at 420 V DC, with capacitance tolerance ±20% (120 Hz, 20°C).
• High‑Temperature Endurance — Designed to withstand 2000 hours of rated ripple current at 105°C when DC bias plus rated ripple current is applied and peak voltage does not exceed the rated voltage.
• Ripple Current Performance — Rated ripple current of 900 mA at 120 Hz and 1.035 A at 10 kHz; frequency coefficients provided to scale ripple capability (e.g., 1.00 at 120 Hz, 1.15 at 10 kHz or more).
• Operating Temperature Range — Specified for −25°C to +105°C operation.
• Package & Mounting — Snap‑in terminal, radial can package (φ35 × 25 mm), intended for secure board mounting in power assemblies.
• Electrical Quality — Low loss tangent (tan δ ≤ 0.20 at 120 Hz, 20°C) and leakage current specified as I ≤ 3√C (µA) after 5 minutes at rated voltage, supporting predictable performance.
• Safety Features — Pressure relief vent and improved safety design to mitigate hazardous conditions under abnormally excessive voltage.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power equipment — Bulk filtering and energy storage where a 420 V, 180 µF polarized capacitor is required.
• Equipment in voltage‑fluctuating areas — Engineered for systems experiencing supply variation, with enhanced safety measures for abnormal voltage events.
• High‑temperature installations — Use in applications that demand sustained ripple handling at elevated ambient or operating temperatures up to 105°C.

Unique Advantages

• Higher ripple capability than LAQ: Delivers increased ripple current handling compared with the LAQ series, enabling smaller case sizes without sacrificing performance.
• Long high‑temperature life: Endurance rating of 2000 hours at 105°C under rated ripple current supports longer service life in demanding thermal environments.
• Compact snap‑in form factor: φ35 × 25 mm radial can with snap‑in terminals provides a space‑efficient, robust mounting option for power assemblies.
• Predictable electrical behavior: Specified tan δ and leakage current limits yield stable AC and DC performance for filtering and energy storage functions.
• Built‑in safety design: Pressure relief vent and measures for abnormal voltage reduce the risk of hazardous failure modes during overvoltage events.
• Regulatory compliance: RoHS conformity supports use in designs targeting restricted‑substance compliance.
