LGN2H151MELA45

The LGN2H151MELA45 is a Nichicon LGN series aluminum electrolytic capacitor in a snap‑in, radial can package. It delivers 150 µF capacitance at a 500 V rating and is polarized for DC applications.

Designed for general‑purpose power electronics requiring high temperature endurance, this component is specified for operation from –25°C to 105°C and is capable of withstanding 3000 hours of rated ripple current at 105°C. The part is RoHS compliant.

Key Features

• Electrical Performance — 150 µF rated capacitance with ±20% tolerance (–20% to +20%). Rated voltage is 500 V DC.
• High Temperature Endurance — Specified to withstand 3000 hours of D.C. bias plus rated ripple current at 105°C; after endurance the capacitance remains within ±20% and leakage current stays within initial specified limits.
• Rated Ripple Current — 750 mA at 120 Hz and 1.073 A at 100 kHz, specified for the part’s rated conditions.
• Operating Temperature Range — –25°C to +105°C for voltage ratings from 350 V to 600 V (applicable to this 500 V part).
• Package and Mounting — Snap‑in radial can package for secure PCB mounting and high current handling; physical size L: 4.5 × D: 2.5 cm with a maximum seated height of 1.772 inch.
• Leakage Current Specification — Meets leakage current requirement I ≤ 3/√C (µA) after 5 minutes’ application of rated voltage at 20°C, per datasheet definition.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General purpose power electronics — Provides bulk capacitance and energy storage in systems that require 150 µF at 500 V with high temperature endurance.
• Industrial power supplies — Suited for circuits where extended ripple current life at 105°C is required.
• High‑voltage DC filtering — Snap‑in mounting and the 500 V rating make the part applicable where polarized high‑voltage capacitance is needed on board.

Unique Advantages

• 500 V rated voltage — Supports high‑voltage DC applications without compromising on capacitance.
• Proven high‑temperature durability — Rated to withstand 3000 hours of rated ripple current at 105°C, providing predictable long‑term performance in elevated ambient conditions.
• Frequency‑characterized ripple handling — Specified ripple current values at both 120 Hz and 100 kHz allow designers to assess performance across common power frequencies.
• Compact snap‑in form factor — Radial, snap‑in can design and a case one rank smaller than LGU help save PCB space while maintaining robust mounting.
• Controlled leakage behavior — Leakage current bounded by datasheet formula after rated voltage application, aiding design margin and reliability calculations.
• RoHS compliance — Meets relevant RoHS directives for environmentally restricted substances.
