LAS2W101MELZ30

The LAS2W101MELZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAS series, rated 100 µF at 450 V and designed for elevated-temperature, high‑voltage applications. It is a smaller-sized, radial can (snap-in) solution intended for general-purpose use where voltage fluctuation and robust ripple handling are required.

Key value propositions include a 105°C permissible operating range with enhanced safety for abnormal overvoltage conditions, extended endurance under rated ripple current, and RoHS compliance for regulatory compatibility.

Key Features

• Capacitance and Voltage — 100 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable for high-voltage smoothing and filtering tasks.
• High-Temperature Endurance — Specified for operation from −25°C to +105°C and proven to withstand 2000 hours of D.C. bias plus rated ripple current at 105°C.
• Ripple Current Performance — Rated ripple current of 710 mA at 120 Hz and 816.5 mA at 10 kHz, enabling effective AC ripple handling in high-voltage circuits.
• Snap-In Radial Can Package — Snap-in terminal type in a compact radial can (size: L 3 × D 2.2 cm) for secure PCB mounting and reduced board footprint.
• Safety Features — Designed with an operable pressure relief vent and tested under defined overvoltage conditions; for the 450 V rating and capacitance class (100 ≤ C < 220 μF) the datasheet lists limited DC current test conditions and test voltages (e.g., 550 VDC and 675 VDC).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Construction — Standard polarized aluminum electrolytic design for DC power applications.

Typical Applications

• Industrial power equipment — Bulk smoothing and filtering where supply voltage can fluctuate and robust thermal endurance is required.
• High-voltage power supplies — Energy storage and ripple suppression in 400–450 V class DC supplies and related circuits.
• General-purpose electronics — Applications requiring a compact, snap-in high-voltage capacitor with proven endurance at 105°C.

Unique Advantages

• Compact high-voltage capability — Smaller case size while providing 450 V rating and 100 µF capacitance, enabling space-efficient board layouts.
• Long endurance at elevated temperature — Rated to withstand 2000 hours of rated ripple current at 105°C, supporting reliable operation in hot environments.
• Improved overvoltage safety — Built-in pressure relief vent and defined test conditions for abnormal voltage improve safety margins in designs exposed to supply fluctuations.
• High ripple handling — Measured ripple current values at both low and high frequencies (710 mA @ 120 Hz, 816.5 mA @ 10 kHz) reduce heating and extend service life in AC-stressed circuits.
• RoHS compliant — Meets RoHS (2011/65/EU, (EU)2015/863) requirements for materials compliance.
