LAR2G471MELC35

The LAR2G471MELC35 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose high-voltage applications. It delivers 470 µF capacitance at a 400 V rating with polarized construction, a snap‑in radial can package, and an operating range rated to 105°C.

Built for durability under elevated temperature and ripple stress, this part is specified to withstand 2000 hours of rated ripple current at 105°C and includes measures to reduce short incidence under overvoltage conditions. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 400 V, with ±20% tolerance for reliable bulk energy storage in high-voltage circuits.
• High‑Temperature Endurance — Specified endurance of 2000 hours when subjected to rated ripple current at 105°C, supporting sustained operation in elevated-temperature environments.
• Permissible Overvoltage & Safety — Designed for permissible overvoltage; reduction of short incidence is observed when rated voltage × 1.5 is applied. Overvoltage testing criteria are defined in the product specification.
• Ripple Current Performance — Rated ripple current of 1.68 A at 120 Hz and 2.402 A at 50 kHz, with frequency coefficients provided for broader frequency performance planning.
• Package & Mounting — Snap‑in terminal, radial can package for secure panel or chassis mounting; compact footprint with dimensions L: 3.5 × D: 3.5 cm.
• Temperature & Polarization — Polarized capacitor with operating temperature range listed as −25°C to 105°C for the 400 V variant.
• Standards & Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronic Systems — Used where a 470 µF, 400 V polarized capacitor with snap‑in mounting is required for bulk capacitance or energy storage in general-purpose designs.
• High‑Temperature Environments — Suitable for equipment requiring components rated for sustained ripple current at elevated temperature (2000 hours at 105°C).
• High‑Voltage Bulk Storage — Applied in circuits that need high-voltage bulk capacitance in a compact radial can package, taking advantage of the 400 V rating and specified ripple current capability.

Unique Advantages

• Long-term ripple endurance: 2000‑hour rating at 105°C under rated ripple current, supporting designs that experience continuous ripple stress.
• Overvoltage robustness: Design and testing address reduced short incidence when exposed to 1.5× rated voltage, improving failure-mode behavior under abnormal conditions.
• Frequency-aware ripple specs: Published ripple current values at 120 Hz and 50 kHz (1.68 A and 2.402 A respectively) and frequency coefficients allow accurate thermal and ripple planning across frequencies.
• Installation-ready form factor: Snap‑in radial can simplifies mechanical mounting for chassis or power assembly integration.
• Regulatory compliance: RoHS conformity supports use in products targeting restricted-substance compliance.
