LGU1H272MELA

The LGU1H272MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, offering 2.7 mF (2700 µF) capacitance at 50 V. Designed for general‑purpose power applications, it provides bulk capacitance with robust ripple current capability and high‑temperature endurance.

Key value comes from its high ripple current ratings, extended 105°C endurance, and compact radial snap‑in package, making it suitable where reliable energy storage and smoothing are required under elevated operating temperatures.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 50 V with ±20% tolerance for bulk energy storage and smoothing.
• High‑Temperature Endurance — Rated to operate from −40°C to 105°C with a guaranteed life of 3000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Low frequency ripple current of 1.7 A (120 Hz) and high frequency ripple current of 1.955 A (50 kHz), enabling effective filtering across a range of switching frequencies.
• Loss and Leakage — tan δ of 0.30 (measured at 20°C, 120 Hz) and leakage current specified at 1100 µA, providing predictable AC loss and DC leakage behavior.
• Package & Mounting — Radial snap‑in can (φ25 × 25 mm) for secure board mounting; supplied in tray packing and available in mass production quantities.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in general‑purpose power supplies, leveraging 2.7 mF capacitance and high ripple current ratings.
• Power electronics — Filtering and energy buffering in industrial and commercial power circuits that require operation up to 105°C and long endurance (3000 h at 105°C).
• Decoupling for high‑frequency converters — Supports switching applications with its specified high‑frequency ripple current (1.955 A at 50 kHz) to reduce voltage ripple at converter outputs.

Unique Advantages

• High ripple handling: Specified ripple currents at both low and high frequencies ensure reliable performance across a range of switching conditions.
• Extended high‑temperature life: 3000 hours endurance at 105°C provides predictable long‑term performance in elevated ambient environments.
• Compact snap‑in form factor: φ25 × 25 mm radial snap‑in can simplifies PCB mounting while providing substantial capacitance in a small footprint.
• Clear electrical characterization: Specified tan δ and leakage current values (0.30 and 1100 µA) allow straightforward thermal and leakage budgeting in designs.
• Production readiness: Tray packing and mass‑production status support scalable procurement for volume designs.
• RoHS compliance: Meets environmental requirements for restricted substances.
