LGR2W151MELA50

The LGR2W151MELA50 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGR long‑life series. It provides 150 µF capacitance at a 450 V rated voltage in a radial, snap‑in can designed for general‑purpose power applications.

Designed for high‑temperature endurance, this part is specified for operation to 105°C with a long‑life assurance of 10,000 hours under rated ripple current at 105°C, making it suited to demanding industrial and power‑electronics environments that require extended reliability.

Key Features

• Capacitance and Voltage — 150 µF rated capacitance at 450 V for high‑voltage energy storage and decoupling in power circuits.
• Long‑Life Endurance — Specified to withstand 10,000 hours of rated ripple current at 105°C per the LGR series long‑life specification.
• High Temperature Operation — Operating temperature range of −25°C to 105°C to support high‑temperature system environments.
• Ripple Current Performance — Rated ripple current of 790 mA at 120 Hz and 1.13 A at 50 kHz to support both low‑ and high‑frequency applications.
• Mounting and Package — Snap‑in terminal, radial can package for secure board mounting and efficient assembly.
• Polarized with Standard Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% (±20%).
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.
• Leakage Current Specification — Leakage current governed by the series specification (I ≤ 3√CV μA after 5 minutes at 20°C) as provided in the datasheet.
• Compact Footprint — Physical size L: 5 × D: 2.5 cm with a seated height of 1.969 inch, suitable for space-conscious power assemblies.

Typical Applications

• Industrial Power Supplies — High‑voltage filtering and energy storage where long‑life performance at elevated temperature is required.
• Power Conversion — Bulk smoothing and ripple handling in inverters, converters, and DC‑DC stages that operate with significant ripple currents.
• Electronic Equipment — General‑purpose power conditioning in factory and commercial electronics that demand robust, long‑life capacitors.

Unique Advantages

• Extended Service Life: 10,000‑hour endurance at 105°C reduces frequency of replacements and maintenance in high‑temperature installations.
• High‑Voltage Capability: 450 V rating supports higher‑voltage power rails and allows fewer capacitors in series or parallel configurations for a given application.
• Strong Ripple Handling: Specified ripple current at both 120 Hz and 50 kHz ensures reliable performance across common power and switching frequencies.
• Snap‑In Mounting: Snap‑in terminal design provides secure mechanical retention and simplifies assembly for vertical power modules and boards.
• Regulatory Compliance: RoHS conformity supports use in products where restricted substance compliance is required.
• Predictable Leakage Behavior: Datasheet leakage current specification (I ≤ 3√CV) enables designers to budget for standby losses and thermal effects.
