LGN2D182MELB50

The LGN2D182MELB50 is a polarized aluminum electrolytic capacitor in a snap‑in radial can package designed for general‑purpose power applications. It combines a 1.8 mF capacitance with a 200 V rated voltage and snap‑in terminals for secure PCB mounting.

Built for elevated temperature operation, this part withstands continuous rated ripple current for 3000 hours at 105°C and is RoHS compliant, offering a compact, durable option where high ripple handling and long high‑temperature endurance are required.

Key Features

• Capacitance & Voltage — 1.8 mF capacitance with a 200 V rated voltage and ±20% tolerance for predictable bulk energy storage and decoupling.
• High‑Temperature Endurance — Rated for operation up to 105°C with endurance of 3000 hours when subjected to DC bias plus rated ripple current at 105°C.
• Ripple Current Performance — Rated ripple current of 3.08 A at 120 Hz and 4.62 A at 100 kHz to support circuits with significant AC current content.
• Package & Mounting — Snap‑in terminal type in a radial can package for robust mechanical retention and straightforward assembly into power modules and chassis.
• Polarized Design — Polarized electrolytic construction for applications requiring DC capacitance.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), supporting environmental and regulatory requirements.
• Compact Footprint — Smaller‑sized case (one rank smaller than LGU series) with physical dimensions approximately L: 5 × D: 3 cm for space‑constrained layouts.

Typical Applications

• General‑purpose power circuits — Suitable where a polarized aluminum electrolytic capacitor with snap‑in mounting and a 200 V rating is required for bulk storage or smoothing.
• High‑ripple‑current circuits — Appropriate for circuits that must tolerate sustained ripple currents up to 3.08 A (120 Hz) or 4.62 A (100 kHz).
• Elevated‑temperature installations — Fits applications operating at or near 105°C that require an electrolytic capacitor rated for long endurance under high temperature stress.
• Snap‑in power modules — Designed for assemblies that benefit from snap‑in radial cans for secure, vibration‑resistant mounting.

Unique Advantages

• Long high‑temperature endurance: 3000 hours of rated ripple‑current application at 105°C provides predictable lifespan under thermal stress.
• Measured ripple capability: Specified ripple currents at both low and high frequencies (3.08 A @ 120 Hz, 4.62 A @ 100 kHz) allow designers to size components confidently for AC loading.
• Space‑efficient package: One rank smaller case than the LGU series offers reduced board area for equivalent function, aiding compact power designs.
• Secure mechanical retention: Snap‑in radial can simplifies assembly and improves reliability in vibration environments compared with loose terminal types.
• Regulatory alignment: RoHS compliance supports use in designs requiring restriction of hazardous substances.
