LAR2G271MELZ50

The LAR2G271MELZ50 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAR series. It provides 270 µF capacitance at a 400 V rating in a radial, snap-in can (22 mm diameter × 50 mm length) designed for general-purpose electronic applications.

Engineered for high-temperature operation, this capacitor withstands rated ripple current for 2000 hours at 105°C and includes features to reduce short incidence under overvoltage conditions. The part is RoHS compliant.

Key Features

• Rated Capacitance and Voltage — 270 µF nominal capacitance with a 400 V rated voltage; capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• High-temperature Endurance — Endurance specified as 2000 hours at 105°C with D.C. bias plus rated ripple current applied; capacitance change within ±20% and leakage current within initial specified value after the test.
• Snap-in Radial Can Package — Snap-in terminal type in a radial can for secure mounting; package dimensions L: 50 mm × D: 22 mm.
• Ripple Current Capability — Specified ripple current: 1.22 A at 120 Hz and 1.745 A at 50 kHz; frequency coefficients defined for higher-frequency operation in the LAR series data.
• Operating Temperature Range — Rated for −25°C to +105°C for the 400 V variants in the LAR series.
• Leakage and Dissipation — Leakage current specified by I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) max. 0.15 for 200–400 V types (measured at 120 Hz, 20°C).
• Overvoltage Safety Behavior — Designed with reduced short incidence when subjected to overvoltage (rated voltage × 1.5); series-level safety performance indicates more than 60% passing under a 1.5× overvoltage test with limited current (1 A), using the pressure relief vent passing condition defined in the datasheet.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk smoothing and decoupling in high-voltage power supplies where a 400 V rating and 270 µF capacitance are required.
• Industrial Power Modules — Energy storage and ripple handling in industrial power equipment designed to operate up to 105°C.
• High-frequency Power Electronics — Components that require specified ripple current performance across a range of frequencies, benefiting from the provided ripple current and frequency-coefficient data.

Unique Advantages

• Long High-temperature Endurance: Specified for 2000 hours at 105°C under rated ripple current, supporting reliable operation in elevated-temperature environments.
• Overvoltage Safety Consideration: Series-level design and testing reduce the incidence of shorts when exposed to 1.5× rated voltage, improving robustness under abnormal conditions.
• Compact High-voltage Form Factor: 270 µF at 400 V in a 22 mm diameter snap-in can provides a space-efficient solution for high-voltage bulk capacitance.
• Quantified Ripple Performance: Published ripple current figures (1.22 A at 120 Hz, 1.745 A at 50 kHz) and frequency coefficients allow designers to size components against expected operating spectra.
• Regulatory Compliance: RoHS conformity simplifies use in regulated markets and product flows.
