LAR2E331MELA25

The LAR2E331MELA25 is a Nichicon LAR series snap‑in terminal aluminum electrolytic capacitor rated at 330 µF and 250 V. It is a polarized, radial can snap‑in package designed for general‑purpose power applications that require high-temperature endurance and robust ripple handling.

Engineered for durability at elevated temperatures, this capacitor is specified for operation from –40°C to +105°C and is RoHS compliant, providing a reliable bulk-capacitance option for power electronic designs.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑Temperature Endurance — Specified lifetime of 2000 hours at 105°C when subjected to DC bias plus rated ripple current; capacitance change remains within ±20% after test.
• Permissible Overvoltage and Safety — Designed to reduce short incidence when exposed to overvoltage (rated voltage × 1.5). Safety test condition: limited current 1 A with more than 60% of units meeting passing criteria.
• Ripple Current Performance — Rated ripple current of 1.2 A at 120 Hz and 1.8 A at 50 kHz; frequency coefficients for 200/250 V are provided (for example: 120 Hz = 1.00, 50 kHz or more = 1.50) to scale ripple capability by frequency.
• Electrical Characteristics — Leakage current specification I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ (dissipation factor) max 0.15 for 200–400 V range.
• Wide Operating Temperature — Rated for –40°C to +105°C (category temperature range for 200 and 250 V), with defined impedance ratios for low‑temperature stability (Z ratios vs. +20°C).
• Package and Mounting — Radial can, snap‑in terminal type for secure board mounting and straightforward assembly; physical footprint L: 2.5 × D: 2.5 cm with seated height max 2.5 cm.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Designs — Provides bulk capacitance and ripple handling in applications where a 330 µF, 250 V polarized aluminum electrolytic capacitor is specified.
• High‑Temperature Operating Environments — Suited for designs requiring reliable performance up to +105°C with long endurance under rated ripple conditions.
• Board‑Mounted Power Modules — Snap‑in radial can package supports secure insertion and mechanical stability in panel or PCB power assemblies.

Unique Advantages

• Proven High‑Temperature Reliability — 2000‑hour endurance at 105°C under rated ripple validates sustained performance for demanding thermal environments.
• Improved Overvoltage Behavior — Designed to reduce short incidence under 1.5× rated voltage stress, improving system safety margins during transient events.
• Frequency‑Aware Ripple Capacity — Published ripple current ratings plus frequency coefficients allow designers to predict ripple handling across a broad frequency range.
• Measurable Leakage and Loss Limits — Defined leakage current formula and tan δ limits provide clear electrical acceptance criteria during incoming inspection and design validation.
• RoHS Compliance — Meets RoHS directive requirements for materials, supporting regulatory and environmental goals.
• Snap‑In Mounting — Radial snap‑in construction simplifies assembly and secures the component for robust mechanical retention on PCBs or panels.
