LAR2D122MELC30

The LAR2D122MELC30 is a Nichicon LAR series aluminum electrolytic capacitor in a snap‑in radial can package. It provides 1.2 mF (1200 µF) nominal capacitance at a 200 V rated voltage with polarized terminals and a φ35 × 30 mm form factor.

Engineered for general‑purpose electronic equipment, this snap‑in capacitor delivers high capacitance in a compact radial package with specified endurance at elevated temperature and defined ripple current performance for robust power-handling applications.

Key Features

• Electrical Capacity — 1.2 mF (1200 µF) nominal capacitance at 200 V with ±20% tolerance (120 Hz, 20°C).
• High‑temperature Endurance — Rated to withstand 2000 hours of rated ripple current at 105°C with DC bias applied; capacitance change remains within ±20% after the endurance test.
• Ripple Current Performance — Specified ripple current of 2.65 A at 120 Hz and 3.975 A at 50 kHz; frequency coefficients for rated ripple current are provided for design scaling across frequencies.
• Safety Performance under Overvoltage — Designed for a reduction in short incidence when subjected to 1.5× rated voltage; when overvoltage (rated ×1.5) with limited current (1 A) is applied, more than 60% of capacitors meet the passing condition (pressure‑relief vent operates normally or does not open for 10 minutes without short or flame).
• Leakage Current Specification — Leakage current meets I ≤ 3√(C·V) µA after 5 minutes' application of rated voltage at 20°C (C in µF, V in V).
• Package & Mounting — Snap‑in terminal, radial can (φ35 × 30 mm), suitable for board insertion where a secure, low-profile radial mounting is required.
• Operating Range & Compliance — Operating temperature range from −40°C to +105°C (200 V rating) and RoHS compliant.

Typical Applications

• General‑purpose electronic equipment — Provides high capacitance and high-voltage capability for bulk energy storage and decoupling in a wide range of general‑purpose systems.
• Power modules and assemblies — Snap‑in radial package and defined ripple/endurance characteristics make it suitable for power assemblies requiring sustained ripple handling at elevated temperatures.
• Industrial power equipment — Rated for operation to 105°C with 2000‑hour ripple endurance, supporting demanding thermal environments in general industrial applications.

Unique Advantages

• High capacitance at a 200 V rating — 1.2 mF nominal capacitance delivers substantial energy storage in a compact radial can form factor.
• Proven high‑temperature endurance — Endurance specified for 2000 hours at 105°C under rated ripple current provides predictable long‑term behavior in hot operating conditions.
• Frequency‑aware ripple rating — Published ripple current values and frequency coefficients allow designers to scale ripple capability across application frequencies with confidence.
• Improved safety under overvoltage — Design and testing reduce incidence of shorting when exposed to 1.5× rated voltage, with defined passing criteria during overvoltage testing.
• Compliance and testable leakage — Leakage current defined by the I ≤ 3√(C·V) rule and RoHS compliance support regulatory and design verification needs.
