LGR2W181MELC35

The LGR2W181MELC35 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGR Long Life series. It provides a 180 µF capacitance at a 450 V rated voltage in a radial, can-style snap‑in package designed for general‑purpose applications.

Engineered for durability, this device is specified for continuous ripple current operation at elevated temperature and is RoHS compliant, making it suitable for designs that require long life and high voltage handling in polar capacitor applications.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Snap‑in Terminal Package — Radial, can‑style snap‑in mounting for secure board or chassis installation.
• High‑Temperature Long Life — Specified for 10,000 hours of endurance at 105°C under DC bias plus rated ripple current; capacitance change remains within ±25% after the endurance test.
• Ripple Current Capability — Rated ripple current of 870 mA at 120 Hz and 1.244 A at 50 kHz, supporting applications with continuous AC ripple requirements.
• Operating Temperature Range — Rated for operation from −25°C to +105°C.
• Leakage, Dissipation and Stability — Leakage current and tan δ meet series limits; endurance and shelf‑life specifications are defined in the LGR datasheet.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Printed with white lettering on a black sleeve for clear part marking.

Typical Applications

• General‑purpose electronic assemblies — Use where a polarized aluminum electrolytic capacitor with snap‑in mounting is required for board or chassis installations.
• High‑voltage, long‑life designs — Suitable for circuits that require a 450 V rated capacitor with proven endurance at elevated temperature.
• Power modules and power assemblies — Applicable in assemblies that benefit from high ripple current capability and snap‑in mounting for secure mechanical retention.

Unique Advantages

• 450 V rating: Supports higher‑voltage designs without need for series stacking of lower‑voltage capacitors.
• Long‑life assurance: Endurance specified at 10,000 hours at 105°C under rated ripple, providing predictable aging and replacement planning.
• Measured ripple performance: Explicit ripple current values at 120 Hz and 50 kHz allow engineers to size capacitors against real ripple loads.
• Snap‑in package: Radial can with snap‑in terminals simplifies mechanical assembly for bulkhead or PCB mounting in power enclosures.
• RoHS compliance: Conforms to current RoHS directives for easier integration into regulated product lines.
