LGN2G151MELY40

The LGN2G151MELY40 is a snap‑in terminal type aluminum electrolytic capacitor rated 150 µF at 400 V, designed for general‑purpose power applications. It is a smaller‑sized, high‑temperature device rated to 105°C and built to withstand extended ripple stress.

Engineered for reliable performance in demanding thermal and ripple environments, this part delivers long endurance and robust ripple current capability while meeting RoHS (2011/65/EU, (EU)2015/863) requirements.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage; capacitance tolerance ±20% (at 120 Hz, 20°C).
• High‑Temperature Endurance — Endurance specified for 3000 hours at 105°C when subjected to DC bias plus rated ripple current; restored measurements are specified after recovery to 20°C.
• Ripple Current Performance — Rated for 850 mA at 120 Hz and 1.216 A at 100 kHz, supporting bulk filtering and smoothing under continuous ripple conditions.
• Package & Mounting — Radial, can snap‑in package for secure board mounting; compact footprint with dimensions L: 4 × D: 2 cm and a maximum seated height of 1.575 inch.
• Operating Range — Specified operating temperature range of −25°C to +105°C for the 400 V rating.
• Leakage & Stability — Leakage current defined by the series specification (I ≤ 3/√C µA after 5 minutes at 20°C) and low‑frequency impedance stability per datasheet; tan δ and impedance characteristics conform to series limits.
• Compliance — RoHS compliant to 2011/65/EU and (EU)2015/863 requirements.
• Compact Size Advantage — One rank smaller case size than the LGU series, enabling denser board layouts where space is constrained.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple suppression in high‑voltage power modules where a 400 V rated capacitor is required.
• Industrial power equipment — Energy storage and decoupling in industrial control and power conversion systems that operate at elevated temperatures.
• General purpose power circuits — Board‑mounted snap‑in solutions for general‑purpose high‑voltage applications requiring reliable long‑term endurance.

Unique Advantages

• Long high‑temperature life — Specified 3000‑hour endurance at 105°C under rated ripple current, enabling predictable life in thermally stressed designs.
• High ripple handling — Dual ripple current ratings (850 mA at 120 Hz, 1.216 A at 100 kHz) that support sustained AC stress and reduce heating under ripple loads.
• Space‑efficient packaging — One rank smaller case than the LGU family helps reduce PCB footprint without sacrificing voltage or capacitance.
• Secure mechanical mounting — Snap‑in radial can provides robust retention for through‑hole installations in vertical assemblies.
• Regulatory compliance — RoHS compliance supports designs targeting global regulatory requirements.
