LGR2G121MELA35

The LGR2G121MELA35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGR long‑life series. It provides 120 µF capacitance at a 400 V rating in a radial, can-style snap‑in package designed for general‑purpose applications.

Engineered for sustained operation at elevated temperature, this part is specified for continuous performance up to 105°C with a long‑life endurance of 10,000 hours under rated ripple and DC bias conditions, making it suitable for designs that require durable high‑voltage bulk capacitance.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 400 V rated voltage, providing high‑voltage bulk energy storage.
• High‑temperature Long Life — Designed for operation up to 105°C and rated for 10,000 hours of endurance at 105°C under rated ripple and DC bias.
• Ripple Current Capability — Rated ripple current of 750 mA at 120 Hz and 1.073 A at 50 kHz, suitable for applications with significant AC ripple components.
• Mounting & Package — Snap‑in terminal, radial can (snap‑in) package for secure board retention and easy insertion into suitable assemblies.
• Electrical Characteristics — Polarized aluminum electrolytic with tolerance of −20% to +20% and leakage current specified per datasheet formula.
• Operating Range — Specified operating temperature range of −25°C to +105°C for use in elevated temperature environments.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and filtering in high‑voltage DC circuits where 400 V rated capacitance is required.
• High‑temperature long‑life systems — Power electronics and equipment that require sustained capacitor performance at elevated ambient temperatures up to 105°C.
• PCB snap‑in assemblies — Applications that benefit from snap‑in mechanical retention for secure placement of a radial can capacitor.
