LAR2W221MELB30

The LAR2W221MELB30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAR series, rated 450 V with a nominal capacitance of 220 µF. It is a radial, can-style snap-in device designed for general-purpose use where high-voltage filtering, bulk energy storage and ripple handling are required.

With a φ30×30L package and an operating temperature range of −25 °C to +105 °C, this capacitor combines high-voltage capability with extended high-temperature endurance and safety-focused construction for reliable performance in industrial and power-electronics applications.

Key Features

• Voltage Rating — 450 V Suitable for high-voltage DC applications requiring robust dielectric performance.
• Capacitance — 220 µF ±20% Nominal capacitance with ±20% tolerance at 120 Hz, 20 °C for bulk filtering and energy storage.
• Snap-in Radial Can Package Φ30×30L (approx. 30 mm diameter × 30 mm length) can with snap-in terminals for secure chassis/board mounting and reliable mechanical retention.
• High-Temperature Endurance Rated to withstand 2000 hours of rated ripple current at 105 °C, enabling extended operation under elevated temperature and ripple stress.
• Overvoltage Safety Performance Designed to reduce short incidence when exposed to overvoltage (1.5× rated voltage); safety testing shows more than 60% of capacitors pass under a 1.5× Vtest with limited current conditions.
• Ripple Current Capability Specified ripple current of 1.05 A at 120 Hz and 1.502 A at 50 kHz; frequency coefficient for 400–450 V group is 1.00 at 120 Hz and 1.43 at 50 kHz or higher.
• Leakage Current and Loss Angle Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20 °C; maximum tan δ of 0.20 at 450 V (measured at 120 Hz, 20 °C).
• Operating Temperature Rated for −25 °C to +105 °C (category temperature range for 400–450 V), matching the LAR series high-voltage specifications.
• RoHS Compliant Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies and Converters Bulk smoothing and filtering for high-voltage DC rails in industrial and commercial power supplies.
• Switching Power Systems DC-link and ripple current handling in switch-mode power supplies and inverter input stages.
• Industrial Electronics Energy storage and voltage stabilization in control systems, drives, and general-purpose industrial equipment.

Unique Advantages

• High-voltage capability in a compact can: 450 V rating in a φ30×30 package enables high-voltage designs without excessive board area.
• Long life under thermal and ripple stress: Withstands 2000 hours of rated ripple current at 105 °C, supporting durable performance in elevated-temperature environments.
• Designed-in overvoltage safety: Reduced incidence of shorts under 1.5× rated voltage with standardized safety testing demonstrating pass behavior for a majority of units.
• Frequency-aware ripple performance: Specified ripple currents at 120 Hz and high frequency plus published frequency coefficients help predict behavior across switching frequencies.
• Measured electrical parameters: Defined leakage current limits and tan δ values provide clear, testable electrical performance criteria for design integration.
• Regulatory compliance: RoHS conformity supports regulatory and environmental requirements.
• Secure mounting: Snap-in radial can package provides robust mechanical retention for chassis-mounted and board-mounted designs.
