LAR2E182MELC50

The LAR2E182MELC50 is a Nichicon LAR series aluminum electrolytic capacitor in a snap-in terminal, radial can package. It delivers 1800 µF capacitance at a 250 V rating, designed for general-purpose power applications that require high ripple handling and robust thermal endurance.

Engineered for sustained operation up to 105°C, this capacitor targets power-supply smoothing, DC-link and energy-storage roles in industrial and commercial equipment where durable performance and safety under occasional overvoltage are important.

Key Features

• Capacitance & Voltage — 1800 µF nominal capacitance at a 250 V rated voltage with ±20% tolerance.
• High-temperature Endurance — Rated for continuous operation to 105°C with specified endurance of 2000 hours when subjected to DC bias plus rated ripple current.
• Snap-in Radial Can Package — Snap-in terminal mounting for secure PCB installation; physical size φ35 × 50 mm (L: 5 × D: 3.5 cm) with a maximum seated height of 1.969 inches.
• Ripple Current Capability — Rated ripple current 2.7 A at 120 Hz and frequency-adapted performance up to 4.05 A at 50 kHz; frequency coefficients provided for scaling ripple current across 50 Hz to 50 kHz ranges.
• Electrical Characteristics — Leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ maximum 0.15 at 120 Hz for 200–400 V series ratings.
• Low-temperature Stability — Impedance ratios specified for low-temperature performance: Z(-25°C)/Z(+20°C) = 3 and Z(-40°C)/Z(+20°C) = 12 for 200–250 V ratings.
• Safety under Overvoltage — Designed to reduce short incidence when subjected to overvoltage (rated voltage × 1.5); tested with a limited current of 1 A and defined passing criteria for pressure relief behavior.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction in industrial and commercial AC/DC and DC/DC converters.
• DC-link and Energy Storage — Energy buffering and transient support in inverter and motor drive assemblies.
• Industrial Electronics — Durable filter and decoupling capacitor for industrial control systems operating in elevated temperature environments.

Unique Advantages

• Long High‑Temperature Life: Specified 2000 hours at 105°C under rated ripple current, supporting reliable performance in hot operating environments.
• Robust Ripple Handling: Clear ripple current ratings and frequency coefficients allow designers to size capacitors accurately for high-frequency and low-frequency applications.
• Snap‑in Mounting Reliability: Snap-in terminal design provides secure mechanical retention for heavy-current PCB implementations.
• Measured Safety Behavior: Overvoltage testing (1.5× rated voltage, limited current) and pressure-relief pass criteria reduce the likelihood of short-circuit incidents under stress.
• Predictable Electrical Limits: Defined leakage current formula and tan δ limits at 120 Hz give transparent criteria for selection and quality assessment.
• Regulatory Compliance: RoHS conformity simplifies use in equipment designed for global markets with restricted substances requirements.
