LGW2D182MELB50

The LGW2D182MELB50 is a snap‑in terminal aluminum electrolytic capacitor designed for high ripple current applications. It delivers 1.8 mF (1800 μF) capacitance at a 200 V rating, polarized construction, and RoHS compliance for general‑purpose electronic designs.

Engineered for elevated temperature operation, this capacitor is specified to operate from −40 °C to 105 °C and is endurance‑tested to withstand 3000 hours of rated ripple current at 105 °C, making it suitable where sustained ripple handling and long thermal endurance are required.

Key Features

• High Capacitance and Voltage: 1.8 mF (1800 μF) nominal capacitance at a 200 V rated voltage for energy storage and bulk filtering in high‑voltage circuits.
• Snap‑in Radial Can Package: Snap‑in terminal, radial can package with dimensions L: 5 × D: 3 cm (approx. 50 mm × 30 mm), designed for secure PCB mounting and mechanical stability.
• High Ripple Current Capability: Rated ripple current of 5.22 A at 120 Hz and 7.83 A at 50 kHz, with frequency coefficients in the LGW series supporting increased ripple at higher frequencies.
• Wide Operating Temperature Range: Specified for −40 °C to +105 °C operation, with endurance testing of 3000 hours at 105 °C under D.C. bias plus rated ripple current.
• Polarized Electrolytic Construction: Polarized design with capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Low Leakage Current Specification: Leakage current specified per I ≤ 3√(C·V) μA after 5 minutes’ application of rated voltage at 20 °C, supporting predictable standby and bias behavior.
• RoHS Compliant: Compliant to the RoHS directive, meeting regulatory requirements for lead‑restricted substances.

Typical Applications

• Power supply filtering: Bulk capacitance and high ripple current capability make this part suitable for smoothing and decoupling in high‑voltage power supplies.
• DC bus and energy storage: 1.8 mF at 200 V provides stored energy for transient management and DC link support in electronic assemblies.
• High‑frequency ripple environments: Rated ripple performance specified at 120 Hz and 50 kHz supports use where both low and high frequency ripple currents are present.

Unique Advantages

• Specifiable ripple endurance: With 3000 hours endurance at 105 °C under rated ripple, the LGW2D182MELB50 provides predictable lifetime performance in thermally demanding applications.
• Frequency‑aware ripple performance: Documented ripple current values at 120 Hz and 50 kHz allow designers to size capacitors based on the actual ripple spectrum of their systems.
• Robust thermal range: −40 °C to +105 °C rating enables deployment across a wide ambient temperature range without exceeding specified limits.
• Clear leakage specification: Leakage current defined by I ≤ 3√CV after voltage application gives a measurable baseline for bias and standby current budgeting.
• PCB‑secure snap‑in termination: Snap‑in radial can package offers reliable mechanical retention for through‑hole board mounting in assemblies requiring sturdy connections.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for product builds.
