LAR2W561MELC50

The LAR2W561MELC50 is an aluminum electrolytic capacitor in a snap‑in radial can package designed for general-purpose applications that require high-voltage capacitance and elevated temperature endurance. It delivers 560 µF nominal capacitance at a 450 V rating with polarization suited for DC use.

Built for robust operation, this capacitor is specified for operation to 105°C with defined ripple-current endurance and safety behavior under overvoltage conditions, and is compliant with RoHS requirements.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, providing substantial high-voltage energy storage in a single component.
• High‑temperature Endurance: Rated operating temperature to 105°C and specified to withstand 2000 hours of rated ripple-current application at 105°C.
• Permissible Overvoltage & Safety Performance: Designed for 105°C permissible overvoltage. Under a test of rated voltage × 1.5 (limited current = 1 A), more than 60% of capacitors pass the defined safety condition (pressure‑relief operation or no short/flame for 10 minutes).
• Ripple Current Capability: Specified ripple current of 1.99 A at 120 Hz and 2.846 A at 50 kHz, with frequency coefficients provided in the series datasheet for other frequencies.
• Low‑temperature Impedance Behavior: For 400–450 V ratings, impedance ratio Z(−25°C)/Z(+20°C) is specified (max. 8), supporting predictable performance across temperature extremes.
• Package & Mounting: Radial, snap‑in can package for secure board mounting in applications requiring through‑hole snap‑in terminals.
• Leakage Current Specification: Leakage current after 5 minutes at 20°C is specified as I ≤ 3√(C·V) µA (C in µF, V in V), enabling designers to budget for leakage in power calculations.
• Regulatory Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power supplies — Bulk smoothing and energy storage where 450 V rating and 560 µF capacitance are required.
• Industrial equipment — Snap‑in radial can packaging provides stable board mounting for high‑voltage capacitors in industrial control and power assemblies.
• High‑temperature environments — Specified operation to 105°C with 2000‑hour ripple endurance for designs that require sustained elevated‑temperature reliability.
• High‑frequency filtering — Rated ripple current values at 120 Hz and 50 kHz support design of filters and DC link circuits with defined ripple handling.

Unique Advantages

• High‑voltage energy density: 560 µF at 450 V provides significant capacitance in a single component, reducing the number of devices required for high‑voltage storage.
• Proven high‑temperature endurance: 2000 hours at 105°C under rated ripple current gives designers a clear, testable reliability metric for thermal stress conditions.
• Measured ripple performance: Published ripple‑current values at 120 Hz and 50 kHz allow accurate thermal and lifetime budgeting in power designs.
• Safety‑oriented overvoltage behavior: Design features reduce short incidence under overvoltage (rated × 1.5) with defined passing criteria, supporting safer failure modes.
• Through‑hole snap‑in mounting: Radial can snap‑in terminals provide mechanical stability for board‑level power applications and simplified assembly.
• RoHS compliance: Meets RoHS directive (2011/65/EU, (EU)2015/863) for environmentally regulated designs.
