LAR2G101MELZ25

The LAR2G101MELZ25 is a snap‑in terminal type aluminum electrolytic capacitor specified at 400 V and 100 µF. Designed for general‑purpose electronic applications, it combines a compact radial can package (22 mm diameter × 25 mm length) with snap‑in mounting for secure board installation.

Engineered for sustained operation at elevated temperature, this capacitor withstands rated ripple current for 2000 hours at 105°C and incorporates measures to reduce short incidence under overvoltage conditions. It is RoHS compliant.

Key Features

• Electrical Rating: 100 µF capacitance at a rated voltage of 400 V, with capacitance tolerance ±20% (120 Hz, 20°C).
• High‑temperature Endurance: Specified to tolerate rated ripple current for 2000 hours at 105°C; endurance tested with DC bias plus rated ripple current.
• Overvoltage Safety Performance: Designed to reduce short incidence when overvoltage (rated voltage × 1.5, limited current = 1 A) is applied; more than 60% of capacitors pass the overvoltage condition per datasheet criteria.
• Ripple Current Capability: Rated ripple current of 680 mA at 120 Hz and 972.4 mA at 50 kHz for this part; frequency coefficients provided in the series datasheet for higher frequencies.
• Low‑temperature and Loss Characteristics: Tan δ (loss tangent) max of 0.15 at 120 Hz, 20°C for 200–400 V parts; impedance ratio specifications for low temperature performance are included in the series data.
• Package & Mounting: Radial can, snap‑in terminal type for secure PCB mounting; physical dimensions approximately 22 mm diameter × 25 mm length.
• Operating Range: Rated for operation from −25°C to +105°C for 400 V parts.
• Leakage Current Specification: Leakage current defined by I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk capacitance and smoothing for circuits that require a 400 V, 100 µF snap‑in electrolytic capacitor.
• Power supply reservoirs — Use where sustained ripple current handling at elevated temperature is required for general‑purpose designs.
• Replacement and repair — Suitable for service or retrofit in designs that specify a radial, snap‑in 400 V, 100 µF aluminum electrolytic capacitor.

Unique Advantages

• High voltage capability: 400 V rating provides margin for high‑voltage general‑purpose applications.
• Proven elevated‑temperature endurance: 2000‑hour rated ripple endurance at 105°C supports long‑term operation under thermal stress.
• Snap‑in mounting for reliable assembly: Radial snap‑in terminals enable secure, repeatable PCB installation in through‑hole assemblies.
• Measured ripple performance: Specified ripple current values at 120 Hz and 50 kHz help designers size capacitors for real operating frequencies.
• Overvoltage safety behavior: Series testing reduces short incidence under 1.5× rated voltage conditions, improving safety margin during abnormal events.
• Regulatory compliance: RoHS conformity supports use in designs targeting restricted‑substance compliance.
