LAR2E471MELB25

The LAR2E471MELB25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAR series. It provides 470 µF capacitance at a rated voltage of 250 V in a radial, can-style snap-in package designed for general-purpose applications.

Engineered for elevated-temperature operation, this part is specified for continuous use up to 105°C and is intended where bulk capacitance, ripple handling and long-term endurance are required in general-purpose electronic designs.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with a rated voltage of 250 V and ±20% tolerance at 120 Hz, 20°C.
• High-temperature operation — Rated for operation from −40°C to +105°C, supporting designs that require elevated operating temperature capability.
• Endurance at 105°C — Meets endurance requirements after 2000 hours at 105°C with D.C. bias plus rated ripple current (capacitance change within ±20%, tan δ within specified limits, leakage current ≤ initial specified value).
• Ripple current capability — Specified ripple current: 1.4 A at 120 Hz and 2.1 A at 50 kHz; frequency coefficients available in the LAR series datasheet for other frequencies.
• Safety under overvoltage — Designed for reduced incidence of short when subjected to overvoltage (1.5× rated voltage) under limited-current test conditions; more than 60% of units pass the specified safety performance criteria.
• Package and mounting — Radial can, snap-in terminal type; compact mechanical dimensions φ30 × 25L mm (size dimension L: 2.5 × D: 3 cm) for board-mounted bulk capacitance.
• Loss and low-temperature stability — tan δ maximum for 200–400 V range is 0.15; impedance ratios vs. +20°C are specified for −25°C and −40°C (Z(−25°C)/Z(+20°C) ≤ 3, Z(−40°C)/Z(+20°C) ≤ 12 for 200/250 V ratings).
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Marking — White lettering on a black sleeve for clear identification.

Typical Applications

• General-purpose electronics — Provides bulk capacitance and energy storage for general-purpose circuits that require 250 V, 470 µF components.
• Power supplies — Suitable for smoothing and bulk filtering in power supply circuits where 105°C operation and specified ripple current handling are required.
• Industrial equipment — Appropriate for industrial designs needing electrolytic capacitance with extended high-temperature endurance and overvoltage safety characteristics.

Unique Advantages

• Extended high-temperature endurance — 2000-hour rated ripple-current endurance at 105°C delivers predictable aging and performance recovery after thermal stress.
• Documented ripple performance — Specified ripple current at common operating frequencies (120 Hz and 50 kHz) and published frequency coefficients help size for AC stress.
• Overvoltage safety consideration — Series-level testing and specification for limited-current overvoltage conditions reduce the incidence of short events under abnormal voltage stress.
• Compact snap-in board mounting — Radial, snap-in can package provides reliable mechanical retention and ease of placement for assemblies needing through-hole bulk capacitance.
• Clear regulatory status — RoHS compliance simplifies integration into designs targeting restricted-substance requirements.
