LAR2G331MELA45

The LAR2G331MELA45 is a 330µF, 400V aluminum electrolytic capacitor in a snap‑in radial can designed for general‑purpose power circuitry. It combines high‑voltage capacitance with a snap‑in mounting style and a compact φ25 × 45 mm can for panel or chassis installations.

Designed for demanding thermal environments, this capacitor withstands 2000 hours of rated ripple current at 105°C and includes safety features that reduce short incidence under overvoltage conditions. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 400 V; capacitance tolerance ±20% (120Hz, 20°C).
• High‑Temperature Endurance — Endurance validated for 2000 hours with D.C. bias plus rated ripple current at 105°C (meets specified capacitance, tan δ and leakage current limits after test).
• Snap‑In Radial Package — Snap‑in terminal type in a radial can (φ25 × 45 mm) for secure, board‑level or chassis mounting and mechanical stability.
• Ripple Current Performance — Rated ripple current: 1.44 A at 120 Hz and 2.059 A at 50 kHz for the specific part configuration; frequency coefficients for 400/450V parts provided in the series datasheet (e.g., 0.77 at 50 Hz, 1.00 at 120 Hz, 1.16 at 300 Hz, 1.43 at 50 kHz+).
• Operating Temperature Range — Specified for operation from −25°C to +105°C.
• Safety Under Overvoltage — Series safety performance: when overvoltage (rated voltage × 1.5, limited current = 1 A) is applied, more than 60% of parts meet passing criteria (pressure relief vent operation or no short/flame for 10 minutes), reducing short incidence.
• Leakage Current Specification — Leakage current limit follows I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C (C in µF, V in V).
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power circuits — Bulk capacitance and DC filtering where 400 V, 330 µF is required and snap‑in mounting is preferred.
• Power supply smoothing — Energy storage and smoothing in high‑voltage DC sections compatible with the part’s rated ripple current and endurance at 105°C.
• Industrial power equipment — Applications needing high‑voltage electrolytic capacitance with durable high‑temperature performance and a robust snap‑in package.

Unique Advantages

• Robust high‑temperature life: 2000 hours at 105°C under rated ripple current supports reliable operation in elevated ambient or internally heated environments.
• High voltage capability: 400 V rating provides substantial DC bus/headroom for high‑voltage power designs.
• Snap‑in mounting convenience: Radial, snap‑in can simplifies mechanical retention and board/chassis installation compared with leaded options.
• Measured ripple performance: Specified ripple currents at 120 Hz and 50 kHz with frequency coefficients for the 400/450V series enable predictable thermal and lifetime planning across switching frequencies.
• Safety‑oriented design: Series overvoltage behavior (1.5× rated voltage test) reduces incidence of shorting, improving system-level fault tolerance.
• Standards compliance: RoHS conformity supports use in equipment targeting regulated markets.
