LAR2G471MELB45

The LAR2G471MELB45 is a Nichicon LAR series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It provides 470 µF capacitance at a 400 V rating with polarized construction and is specified for general-purpose applications that require high-voltage, high-temperature operation.

Designed for demanding thermal and ripple environments, this part offers 105°C operation, a defined 2000‑hour endurance under rated ripple current at 105°C, and safety features that reduce short incidence under overvoltage conditions.

Key Features

• Voltage & Capacitance — 470 µF rated capacitance at 400 V for high‑voltage DC applications.
• High‑Temperature Endurance — Rated for operation up to 105°C with a guaranteed 2000 hours endurance when subjected to D.C. bias plus rated ripple current at 105°C.
• Permissible Overvoltage Behavior — Designed to reduce short incidence when exposed to 1.5× rated voltage; safety test shows passing condition for a majority of parts under specified overvoltage with limited current.
• Ripple Current Performance — Specified ripple current of 1.68 A at 120 Hz and 2.402 A at 50 kHz; frequency coefficients are provided in the series datasheet to scale ripple capability across frequencies.
• Electrical Characteristics — Capacitance tolerance ±20%; leakage current defined as I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ maximum 0.15 for rated voltages up to 400 V (measured at 120 Hz, 20°C).
• Package & Mounting — Radial can with snap‑in terminals for secure chassis/board mounting; part marked with white lettering on a black sleeve.
• Polarized Design — Polar capacitor intended for DC applications where polarity is observed.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power supplies — Provides bulk capacitance and smoothing in general-purpose DC power circuits where 400 V rating and 105°C capability are required.
• Industrial power equipment — Suitable for high‑voltage power modules and assemblies that need robust high‑temperature endurance and defined ripple handling.
• Energy storage and filtering — Used where polarized, high‑voltage capacitance is needed for DC link filtering and energy buffering under elevated temperatures.

Unique Advantages

• High‑voltage capability: 400 V rating enables use in higher DC bus and power conversion circuits.
• Designed for elevated temperatures: 105°C maximum operating temperature with a proven 2000‑hour endurance under rated ripple current increases design confidence in hot environments.
• Snap‑in mounting: Radial can with snap‑in terminals provides mechanically secure mounting for power assemblies.
• Measured ripple specifications: Published ripple current values at 120 Hz and 50 kHz plus frequency coefficients allow predictable derating across application frequencies.
• Overvoltage safety behavior: Series safety performance reduces incidence of shorting under 1.5× rated voltage stress, with specified passing criteria for pressure relief behavior.
• Clear electrical limits: Defined leakage current formula and tan δ limits aid in thermal and loss budgeting during design.
