LAR2W101MELA25

The LAR2W101MELA25 is a snap-in terminal aluminum electrolytic capacitor rated 450 V with 100 µF capacitance in a radial can package (φ25 × 25 mm). It is designed as a general-purpose capacitor for electronic equipment requiring a high-voltage, snap-in mounting solution.

Key engineered attributes include endurance at elevated temperature with sustained ripple performance and a construction that reduces the incidence of shorting under specified overvoltage conditions.

Key Features

• Nominal Capacitance: 100 µF nominal capacitance with ±20% tolerance.
• High Voltage Rating: 450 V rated voltage for high-voltage applications within its specified range.
• Snap-in Radial Can Package: Snap-in terminal type in a radial, can-style package for secure PCB mounting.
• Operating Temperature: Specified for operation from −25 °C to +105 °C.
• Endurance at Elevated Temperature: Withstands 2000 hours of rated ripple current application at 105 °C (endurance criteria: capacitance change within ±20%, tan δ ≤ 200% of initial specified value, leakage current ≤ initial specified value when restored to 20 °C).
• Ripple Current Performance: Specified ripple current of 690 mA at 120 Hz and 986.7 mA at 50 kHz; frequency coefficient details are provided in the datasheet for scaling ripple current across frequencies.
• Improved Overvoltage Safety Performance: Designed to reduce short incidence when subjected to overvoltage at 1.5 × rated voltage (safety performance validated per datasheet condition with limited current).
• Leakage Current Specification: Leakage current meets I ≤ 3√(C·V) (µA) after 5 minutes at 20 °C, per datasheet formula.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — For designs that require a 450 V, 100 µF snap-in aluminum electrolytic capacitor for bulk capacitance and high-voltage service.
• High-Temperature Environments — Suitable where operation up to 105 °C and sustained ripple endurance are required.
• PCB Snap-in Installations — Intended for applications that benefit from snap-in radial can mounting for mechanical stability on the board.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuits requiring reliable electrolytic capacitance.
• Proven thermal endurance: Rated to endure 2000 hours of rated ripple current at 105 °C, delivering predictable aging behavior per the datasheet endurance criteria.
• Measured ripple current data: Published ripple current values at 120 Hz and 50 kHz and frequency coefficients in the datasheet allow predictable ripple handling across frequencies.
• Overvoltage safety measure: Series design reduces incidence of shorting under a 1.5× rated voltage stress condition as described in the datasheet.
• Clear electrical limits: Leakage current defined by the I ≤ 3√(C·V) formula and tan δ limits for 450 V (tan δ ≤ 0.20 at 120 Hz, 20 °C) provide straightforward electrical performance expectations.
• RoHS conformity: Meets current RoHS requirements for environmentally compliant designs.
