LAR2E821MELC30

The LAR2E821MELC30 is a snap-in terminal aluminum electrolytic capacitor rated at 250 V with 820 µF capacitance. It is a polarized, radial can (snap‑in) type designed for general-purpose power applications requiring elevated temperature endurance and reliable ripple handling.

Key value propositions include a 105°C permissible operating range with 2000 hours endurance under rated ripple current, frequency-qualified ripple current performance up to 50 kHz, and reduced short incidence under controlled overvoltage conditions. The part is RoHS compliant.

Key Features

• High voltage / high capacitance — 820 µF capacitance at a 250 V rated voltage, providing substantial bulk energy storage in a compact snap‑in can.
• Snap‑in mounting — Radial, snap‑in package for secure panel or chassis installation and straightforward board mounting.
• 105°C endurance — Withstands 2000 hours of rated ripple current at 105°C, meeting demanding thermal endurance requirements.
• Frequency‑qualified ripple handling — Rated ripple current of 2 A at 120 Hz and 3 A at 50 kHz, with published frequency coefficients for broader operating ranges.
• Reduced short incidence under overvoltage — Designed to reduce short incidence when 1.5× rated voltage is applied (safety behavior defined in series specification).
• Wide operating temperature range — Rated for operation from −40°C to +105°C.
• RoHS compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power equipment — Suited for designs that require a 250 V, 820 µF snap‑in capacitor with elevated temperature endurance for general-purpose power circuits.
• Power supply and DC bus applications — Provides bulk energy storage and ripple buffering where a polarized aluminum electrolytic capacitor is specified.
• Industrial and commercial electronics — Applicable where long endurance at 105°C and reliable ripple performance are required in a snap‑in radial can format.

Unique Advantages

• Long high‑temperature life: 2000 hours endurance at 105°C under rated ripple current supports stability in thermally demanding installations.
• Overvoltage safety behavior: Series-level design reduces short incidence when exposed to 1.5× rated voltage under controlled test conditions.
• Broad ripple performance: Specified ripple currents at 120 Hz and 50 kHz and frequency coefficients enable predictable performance across common operating frequencies.
• Robust operating range: −40°C to +105°C operation covers a wide set of environmental conditions for general-purpose systems.
• Convenient mounting: Snap‑in radial can package simplifies installation in assemblies requiring secure mechanical and electrical connections.
• Regulatory compliance: RoHS conformity supports use in products requiring restricted-substance compliance.
