LGN2G181MELZ35

The LGN2G181MELZ35 is a polarized aluminum electrolytic capacitor in a snap‑in radial can package, designed for general‑purpose power applications. It combines a 180 µF capacitance with a 400 V rated voltage and is optimized for sustained performance at elevated temperature.

Engineered to withstand 3,000 hours of D.C. bias plus rated ripple current at 105°C, this capacitor is intended for designs that require compact snap‑in mounting, high ripple tolerance and RoHS compliance.

Key Features

• Core Electrical — 180 µF nominal capacitance with a 400 V rated voltage; capacitance tolerance is ±20% at 120 Hz, 20°C.
• High‑Temperature Endurance — Specified endurance of 3000 hours at 105°C when D.C. bias plus rated ripple current is applied; meets the LGN series endurance criteria.
• Ripple Current Performance — Rated ripple current of 950 mA at 120 Hz and 1.359 A at 100 kHz, supporting effective filtering and smoothing under AC ripple conditions.
• Wide Operating Range — Operating temperature range from −25°C to +105°C (applicable for the 400 V rating), suitable for elevated‑temperature environments.
• Package & Mounting — Snap‑in terminal, radial can package for secure board retention and simplified assembly; one rank smaller case size than LGU for space‑constrained layouts.
• Polarized Design — Polarized capacitor intended for DC applications requiring axial polarity.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Physical size approximately L: 3.5 × D: 2.2 cm, enabling denser board placement compared with larger snap‑in variants.

Typical Applications

• General‑purpose power filtering — Provides bulk capacitance and ripple smoothing in DC power rails where a 400 V, 180 µF polarized capacitor is required.
• Power supply smoothing — Used for output smoothing and energy buffering in power supply modules that must operate up to 105°C.
• High‑ripple environments — Suitable for circuits that impose sustained ripple current thanks to rated ripple current performance and 3,000‑hour endurance at 105°C.

Unique Advantages

• Compact snap‑in form factor: One rank smaller case size than LGU lets designers save board area without sacrificing capacitance or voltage rating.
• Proven high‑temperature endurance: 3000‑hour rating at 105°C under D.C. bias plus rated ripple current supports reliable long‑term operation in elevated temperatures.
• High ripple capability: Specified ripple currents at 120 Hz and 100 kHz enable effective filtering across common power frequencies.
• Industry‑standard electrical ratings: 400 V and 180 µF provide a useful balance of energy storage and voltage margin for many power designs.
• Regulatory compliance: RoHS compliance simplifies use in markets requiring restricted‑substance conformity.
