LGJ2D181MELY20

The LGJ2D181MELY20 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGJ series, sized in a low‑profile 20 × 20 mm can. It provides 180 µF capacitance at 200 V with ±20% tolerance and is designed for general‑purpose electronic equipment where compact, high‑temperature bulk capacitance is required.

Key value comes from its 105°C operating range, 3000‑hour endurance at 105°C, and robust ripple handling—specifications that support demanding power circuits in a compact snap‑in package for tray‑packed, mass production assemblies.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance rated at 200 V with ±20% tolerance for predictable bulk energy storage.
• High‑Temperature Low‑Profile Package — 105°C rated, low‑profile can sized φ20 × 20 mm (L: 2 × D: 2 cm) for space‑constrained designs.
• Snap‑In Mounting — Radial, can snap‑in package for secure board retention in high‑density assemblies.
• Ripple Current Capability — 680 mA at low frequency (120 Hz) and 1.02 A at high frequency (50 kHz), enabling effective AC ripple handling per the specified frequencies.
• Low Leakage — Specified leakage current of 0.56 mA supports stable performance after voltage application.
• Endurance — Rated for 3000 hours life at 105°C to meet long‑term thermal stress requirements.
• Polarized Electrolytic — Polar construction for general‑purpose power applications where polarity is managed in the design.
• Production Packaging — Tray packing for efficient handling in mass production environments.

Typical Applications

• General‑Purpose Power Circuits — Used where a 200 V, 180 µF electrolytic capacitor is required for bulk capacitance in electronic equipment.
• High‑Temperature Assemblies — Suitable for designs operating up to 105°C requiring extended endurance (3000 h at 105°C).
• Compact Power Modules — Low‑profile φ20 × 20 mm can and snap‑in mounting enable space‑efficient placement in densely packed boards.

Unique Advantages

• Designed for sustained high temperature: 105°C rating and 3000‑hour endurance provide predictable service life under thermal stress.
• High ripple handling: Rated ripple currents of 680 mA (120 Hz) and 1.02 A (50 kHz) help manage AC stress in power conversion and filtering tasks.
• Compact low‑profile form factor: φ20 × 20 mm size offers bulk capacitance without consuming excessive board height.
• Secure snap‑in mounting: Radial snap‑in terminal simplifies mechanical retention for through‑hole assemblies and production handling.
• Low leakage characteristic: 0.56 mA leakage current supports stable performance after voltage application.
• Mass production friendly: Tray packing and series availability support high‑volume assembly processes.
