LAR2D182MELC40

The LAR2D182MELC40 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LAR series, rated 1.8 mF (1800 µF) at 200 V. It is a polarized, radial can snap‑in design intended for general‑purpose high‑voltage DC applications.

Designed for sustained operation at elevated temperatures, this part withstands 2000 hours of rated ripple current at 105°C and includes series features to reduce short incidence under overvoltage conditions. It is RoHS compliant.

Key Features

• Capacitance & Voltage – 1.8 mF (1800 µF) nominal capacitance with a rated voltage of 200 V and capacitance tolerance of ±20%.
• High‑Temperature Endurance – Specified to endure 2000 hours of D.C. bias plus rated ripple current at 105°C with defined limits for capacitance change, tan δ and leakage current after the test.
• Ripple Current Capability – Rated ripple current performance includes 3.08 A at 120 Hz and 4.62 A at 50 kHz, supporting applications with significant AC ripple on the DC bus.
• Operating Temperature Range – Rated for operation from −40°C to +105°C.
• Snap‑In Radial Can Package – Snap‑in terminal design for secure mounting in high‑power assemblies; radial can construction.
• Safety/Overvoltage Behavior – Series design reduces incidence of short when subjected to overvoltage (rated × 1.5); safety performance shows a passing rate under limited‑current overvoltage testing.
• Regulatory Compliance – Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Design – Intended for DC applications requiring polarized electrolytic capacitance.

Typical Applications

• High‑Voltage DC Bus Filtering – Use as smoothing and energy‑storage capacitance on 200 V DC rails where high capacitance and rated voltage are required.
• Power Supply and Converter Designs – Suited for output filtering and bulk capacitance in supplies and converters that encounter sustained ripple current and elevated operating temperatures.
• Industrial Power Electronics – Applicable in general‑purpose industrial equipment where snap‑in mounting, high ripple capability and long‑term high‑temperature endurance are needed.
• General‑Purpose Electronic Equipment – Useful wherever a polarized, high‑capacitance, 200 V electrolytic capacitor is required for energy storage and smoothing.

Unique Advantages

• Sustained High‑Temperature Reliability – Endurance rated for 2000 hours at 105°C under rated ripple current, with specified limits on capacitance change and loss tangent, supports long‑term operation in hot environments.
• Measured Ripple Performance – Published ripple current values (3.08 A at 120 Hz and 4.62 A at 50 kHz) allow designers to size capacitor banks with confidence against expected ripple loads.
• Overvoltage Safety Behavior – Series design reduces short incidence under overvoltage (rated × 1.5) and meets safety performance criteria in limited‑current overvoltage tests.
• Robust Mounting – Snap‑in radial can package provides secure mechanical retention for high‑power PCB assemblies.
• Regulatory Alignment – RoHS compliance supports use in regions and products requiring substance‑restriction conformance.
