LAR2W121MELA30

The LAR2W121MELA30 is a Nichicon aluminum electrolytic capacitor in a snap‑in radial can package, rated 450 V and 120 µF. Designed for general‑purpose high‑voltage power applications, it combines high voltage capability with extended high‑temperature endurance for reliable bulk energy storage and ripple suppression.

Key value propositions include a 2000‑hour endurance at 105°C under rated ripple conditions, RoHS compliance, and a compact φ25 × 30 mm can with snap‑in terminals for secure mounting and tray packing for mass production environments.

Key Features

• High Voltage Rating — Rated for 450 V operation to support high‑voltage power rails and DC link applications.
• Capacitance and Tolerance — 120 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C) for predictable bulk capacitance performance.
• High‑Temperature Endurance — Endurance specified as 2000 hours at 105°C under DC bias plus rated ripple current; capacitance change remains within ±20% after the test.
• Low Loss Characteristic — Tangent of loss angle (tan δ) max 0.20 at 450 V (measured at 120 Hz, 20°C) for controlled dissipation in power circuits.
• Ripple Current Capability — Rated ripple current of 720 mA at 120 Hz and 1.03 A at 50 kHz to handle AC ripple across a wide frequency range.
• Safety and Overvoltage Behavior — Designed to reduce short incidence under 1.5× rated overvoltage; safety testing shows more than 60% pass behavior under specified overvoltage/limited current conditions.
• Leakage Current Specification — Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes' application of rated voltage at 20°C for predictable insulation behavior.
• Package and Marking — Radial, snap‑in can (φ25 × 30 mm) with white printing on a black sleeve; supplied in tray packing suitable for production handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General Power Supplies — Bulk smoothing and ripple filtering on high‑voltage DC rails up to 450 V.
• Industrial Power Electronics — Energy storage and decoupling in power conversion and control equipment where elevated temperature endurance is required.
• DC Link and Converter Circuits — High‑voltage bulk capacitance for converters and inverter front ends that demand stable capacitance and ripple handling.

Unique Advantages

• Long Endurance at Elevated Temperature — 2000 hours at 105°C under rated ripple ensures component longevity in high‑stress environments.
• High‑Voltage Capability — 450 V rating enables use on higher DC rails without series stacking.
• Clear Safety Design Considerations — Reduced incidence of shorts under 1.5× overvoltage and defined pass conditions provide predictable behavior under abnormal stress.
• Broad Ripple Handling — Specified ripple currents at 120 Hz and 50 kHz support a range of switching and line‑frequency applications.
• Production‑Friendly Packaging — Snap‑in radial can and tray packing simplify assembly and handling for volume manufacturing.
• Standards‑Based Leakage Rating — Leakage current defined by I ≤ 3√CV after application of rated voltage for consistent quality control.
