LAS2G181MELA30

The LAS2G181MELA30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor rated 180 µF at 400 V. It is a smaller‑sized, radial can snap‑in capacitor designed for general‑purpose use and for equipment operating in voltage‑fluctuating environments.

Engineered for high‑temperature endurance, the LAS series withstands 2000 hours of rated ripple current at 105°C while offering improved safety features for abnormally excessive voltage. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 180 µF capacitance at a 400 V rated voltage with polarization suitable for DC power applications.
• High‑Temperature Endurance — Designed for operation from −25°C to +105°C and guaranteed to withstand 2000 hours of rated ripple current at 105°C.
• Ripple Current Performance — Rated ripple current of 950 mA at 120 Hz and 1.093 A at 10 kHz; frequency coefficient for rated ripple current increases up to 1.15 at 10 kHz per the series specifications.
• Safety Features — Improved safety measures for abnormally excessive voltage, including a pressure relief vent that activates under normal conditions to avoid dangerous outcomes.
• Compact Snap‑In Package — Radial, can‑type snap‑in mounting for secure PCB retention and compact assembly; smaller case sizes and higher ripple current capability compared with the LAQ series.
• Tolerance & Stability — Capacitance tolerance of ±20% (at 120 Hz, 20°C) with defined endurance and shelf‑life stability margins in the datasheet.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Equipment in voltage‑fluctuating environments — Suited for systems that experience fluctuating line or bus voltages where enhanced safety and voltage tolerance are needed.
• General‑purpose power filtering — Provides bulk capacitance and ripple current handling for DC power smoothing in general industrial and OEM designs.
• Assemblies requiring snap‑in mounting — Ideal where robust through‑hole retention and compact radial can packaging simplify mechanical assembly.
• RoHS‑compliant systems — For designs requiring materials compliance with RoHS (2011/65/EU, (EU)2015/863).

Unique Advantages

• High‑temperature reliability: Rated for −25°C to +105°C and qualified for 2000 hours of rated ripple current at 105°C, delivering predictable lifetime performance under thermal stress.
• Strong ripple‑handling capability: Specified ripple currents of 950 mA (120 Hz) and 1.093 A (10 kHz) help reduce temperature rise and extend service life in high‑stress applications.
• Enhanced safety for abnormal voltage: Pressure relief vent and safety performance tests reduce the risk of hazardous failure modes under abnormal overvoltage conditions.
• Space‑efficient snap‑in form factor: Smaller case sizes compared with the LAQ series allow higher packing density and simplified board assembly while maintaining high ripple capacity.
• Vendor traceability and documentation: Part of Nichicon’s LAS series with defined endurance, shelf‑life, and frequency coefficient data documented in the series specifications.
• Regulatory compliance: RoHS conformity supports use in markets requiring restricted substance compliance.
