LAR2G221MELB25

The LAR2G221MELB25 is a Nichicon LAR series aluminum electrolytic capacitor in a snap-in terminal configuration, rated 400 V and 220 µF. Designed for general-purpose applications, it offers high-voltage capacitance in a compact radial can (φ30×25L) with polarized construction.

Key value propositions include sustained ripple-current endurance at elevated temperature, built-in safety behavior under overvoltage conditions, and RoHS compliance for use in regulated designs.

Key Features

• Rated Capacitance: 220 µF nominal with tolerance ±20% (at 120 Hz, 20°C).
• High Voltage Rating: 400 V DC rated voltage for high-voltage energy storage and filtering needs.
• Snap‑in Terminal Package: Radial can with snap-in terminals (φ30×25L) for secure board mounting.
• High Temperature Endurance: Endurance specified as 2000 hours at 105°C with DC bias plus rated ripple current; after test, capacitance within ±20% and leakage current within initial specified limits.
• Ripple Current Capability: Specified ripple current of 1.1 A at 120 Hz and 1.573 A at 50 kHz; frequency coefficients provided by series datasheet for other frequencies.
• Overvoltage Safety Performance: Designed to reduce incidence of shorting when exposed to 1.5× rated voltage; in safety testing (1.5× rated voltage, limited current 1 A) more than 60% of parts met the passing condition (vent operation or no vent opening for 10 minutes without short or flame).
• Leakage Current Specification: Leakage current meets I ≤ 3√(C·V) µA after 5 minutes' application of rated voltage at 20°C (C in µF, V in volts).
• Operating Temperature Range: Rated for −25°C to +105°C for the 400 V variants in the LAR series.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Low‑temperature Impedance Behavior: For 400–450 V parts, impedance ratio Z(−25°C)/Z(+20°C) is specified (maximum 8) to characterize low‑temperature performance.

Typical Applications

• General Purpose Electronics: Specified as "General Purpose" — suitable where a 400 V, 220 µF polarized snap‑in electrolytic capacitor is required.
• High‑Voltage Power Modules: Applicable in equipment that requires high-voltage DC capacitance within a compact radial can form factor.
• Industrial Equipment: Useful in general industrial designs needing sustained ripple-current endurance at elevated operating temperatures.

Unique Advantages

• Validated High‑Temperature Endurance: 2000 hours at 105°C under rated ripple current provides measurable lifecycle performance for thermal-stressed designs.
• Measured Ripple‑Handling Data: Published ripple-current figures at 120 Hz and 50 kHz allow designers to size capacitors using known frequency coefficients from the LAR series datasheet.
• Overvoltage Mitigation: Series-level safety testing demonstrates reduced short incidence under 1.5× rated voltage conditions, supporting safer failure modes in abnormal conditions.
• Clear Leakage and Loss Specifications: Leakage current formula (I ≤ 3√CV) and tan δ limits are provided for predictable design margins and quality verification.
• Regulatory Compliance: RoHS compliance supports use in regulated product lines requiring restricted substances conformance.
