LAR2G561MELB50

The LAR2G561MELB50 is a Nichicon LAR series aluminum electrolytic capacitor in a snap‑in, radial can package. It offers 560 µF capacitance at a 400 V rating with polarized terminals and is specified for operation up to 105°C.

Designed for general-purpose high-voltage DC applications, this part provides high ripple-current capability and long-term endurance for demanding thermal and electrical environments, while meeting RoHS requirements.

Key Features

• Rated Capacitance & Voltage — 560 µF nominal capacitance at a 400 V rated voltage, with a tolerance of ±20% (at 120 Hz, 20°C).
• High-Temperature Endurance — Specified to withstand 2000 hours of rated ripple-current application at 105°C, supporting sustained thermal stress in high-temperature environments.
• Ripple Current Performance — Rated ripple current of 1.9 A at 120 Hz and 2.717 A at 50 kHz, with published frequency coefficients for elevated-frequency operation in the series datasheet.
• Safety under Overvoltage — Designed to reduce incidence of short when subjected to overvoltage (rated voltage × 1.5); series testing shows more than 60% passing under controlled overvoltage with limited current.
• Electrical Loss and Stability — Low dissipation factor for 400 V parts (tan δ max. 0.15 at 120 Hz, 20°C) and defined low-temperature impedance characteristics to aid design margining.
• Package & Mounting — Radial, snap‑in can type for robust board retention and secure mechanical mounting; physical dimensions approximately L: 5 cm × D: 3 cm with a seated height of up to 1.969 inches.
• Leakage Current Specification — Leakage current specified by I ≤ 3√(C·V) µA after 5 minutes at 20°C (C in µF, V in V), enabling predictable end-of-line qualification and screening.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-Voltage DC Link and Smoothing — Bulk capacitance for 400 V DC link circuits where 560 µF and robust ripple handling are required for energy smoothing.
• Industrial Power Supplies — Energy storage and filtering in industrial power supplies operating in elevated ambient temperatures up to 105°C.
• Power Electronics Subsystems — Use in converters and inverters where polarized high-voltage bulk capacitance and secure snap‑in mounting are needed.
• General-Purpose High-Voltage Filtering — General-purpose applications that require 400 V rated electrolytic capacitance with long endurance under rated ripple current.

Unique Advantages

• Extended High-Temperature Endurance: 2000 hours at 105°C under rated ripple current provides predictable life performance in hot operating environments.
• Reduced Short Incidence under Overvoltage: Series design mitigates shorting when subjected to 1.5× rated voltage during controlled overvoltage conditions, improving system safety behavior.
• Defined Ripple Capability across Frequency: Published ripple current values at 120 Hz and 50 kHz and frequency coefficients allow accurate thermal and lifetime calculations.
• Robust Mechanical Mounting: Snap‑in radial can construction offers secure board retention and simplified assembly for high-voltage power modules.
• Predictable Leakage Behavior: Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes supports consistent screening and quality control.
• RoHS Compliant Manufacturing: Meets RoHS directive requirements for environmentally conscious designs.
