LGR2W151MELC30

The LGR2W151MELC30 is a snap-in terminal aluminum electrolytic capacitor designed for long-life performance in general-purpose, high-voltage applications. It combines a 150 µF capacitance with a 450 V rated voltage and a radial, can-style snap-in package to support robust board mounting and high-voltage filtering or energy storage functions.

Engineered for durability, the part is specified for operation from −25 °C to 105 °C and offers long life assurance with 10,000 hours of rated ripple current at 105 °C. The device is RoHS compliant and provided by Nichicon as part of the LGR long-life series.

Key Features

• 150 µF capacitance — Provides bulk capacitance suitable for smoothing and energy storage in high-voltage circuits.
• 450 V rated voltage — High-voltage rating for circuits requiring elevated DC voltage capability up to 450 V.
• Long-life assurance — Specified for 10,000 hours of endurance under rated ripple current at 105 °C, supporting extended service life in demanding environments.
• Wide operating temperature — Rated for −25 °C to 105 °C to accommodate a broad range of ambient conditions.
• Snap-in radial can package — Snap-in terminals provide a board-mountable, mechanically robust can-style package for through-hole assembly.
• Ripple current capability — Rated ripple currents of 790 mA at 120 Hz and 1.13 A at 50 kHz enable effective AC ripple handling across common frequencies.
• Polarized device with ±20% tolerance — Standard polarization and capacitance tolerance (−20% to +20%) for typical electrolytic capacitor applications.
• Compact footprint — Physical size approximately L: 3 × D: 3.5 cm to fit conventional power-electronics layouts.
• RoHS compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• General-purpose high-voltage circuits — Bulk energy storage and decoupling in circuits that require a 450 V rated capacitor with long operational life.
• Power conversion and filtering — Handling ripple current and smoothing DC at elevated voltages where sustained ripple performance at 120 Hz and higher frequencies is needed.
• Industrial equipment — Use in industrial power modules and assemblies that benefit from a long-life, high-voltage electrolytic in a through-hole snap-in package.

Unique Advantages

• Long endurance at high temperature — 10,000 hours rated life at 105 °C reduces maintenance and replacement frequency in thermal-stressed designs.
• High-voltage capability — 450 V rating allows designers to address higher DC bus voltages without series stacking or complex topologies.
• Excellent ripple handling — Specified ripple current values at 120 Hz and 50 kHz support both low- and high-frequency ripple environments.
• Through-hole snap-in robustness — Snap-in terminals provide reliable mechanical retention for power assemblies and ease of board-level integration.
• Clear specification and compliance — Manufacturer Nichicon’s long-life LGR series data and RoHS compliance provide verifiable environmental and performance credentials.
