LAR2D471MELA25

The LAR2D471MELA25 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power-electronic applications. It provides 470 µF capacitance at a 200 V rated voltage in a radial, can-style snap-in package with polarized terminals.

Engineered for elevated-temperature use, this capacitor is specified for operation from −40 °C to +105 °C and is endurance-rated to withstand 2000 hours of rated ripple current at 105 °C. It also incorporates safety characteristics to reduce short incidence under overvoltage (1.5× rated voltage) conditions and is RoHS compliant.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High‑temperature Endurance — Specified to meet endurance requirements after 2000 hours of DC bias plus rated ripple current at 105 °C, with capacitance change within ±20% and leakage current within initial limits.
• Ripple Current Capability — Rated ripple current 1.48 A at 120 Hz and 2.22 A at 50 kHz, with frequency coefficients provided in the series datasheet for higher-frequency operation.
• Safety / Overvoltage Behavior — Designed to reduce short incidence when exposed to overvoltage (rated voltage × 1.5); safety performance validation includes pressure relief vent behavior under limited-current overvoltage testing.
• Package & Mounting — Radial, can-type snap-in package for secure chassis or PCB mounting; compact footprint with L × D = 2.5 × 2.5 cm and seated height up to 2.5 cm.
• Electrical Loss & Leakage — Low-loss characteristics with tan δ specified (max. 0.15 for 200–400 V at 120 Hz, 20 °C) and a leakage current limit defined by I ≤ 3√(C·V) μA after 5 minutes at 20 °C.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering and smoothing — 470 µF at 200 V and specified ripple current ratings support bulk filtering and smoothing duties in medium-voltage power supplies.
• High-temperature power electronics — Endurance tested for 2000 hours at 105 °C, suitable where sustained elevated-temperature performance is required.
• DC link and energy storage — High capacitance and stable electrical characteristics make it applicable for localized energy storage and DC bus stabilization in general-purpose equipment.

Unique Advantages

• Proven high‑temperature endurance: Endurance rating of 2000 hours at 105 °C ensures predictable performance under prolonged elevated-temperature ripple loading.
• Measured ripple handling: Published ripple current values for 120 Hz and 50 kHz allow designers to size capacitors against actual ripple conditions and frequency coefficients.
• Enhanced safety under overvoltage: Series design reduces short incidence when exposed to 1.5× rated voltage and includes pressure-relief behavior validated by the manufacturer.
• Compact snap‑in packaging: Radial, can-style snap-in mount simplifies secure installation and mechanical retention in power assemblies.
• Clear electrical limits: Defined tan δ and leakage current criteria provide measurable acceptance parameters for QC and design validation.
• RoHS compliance: Meets RoHS directives, supporting regulatory and environmental requirements.
