LGU1E153MELC

The LGU1E153MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, specified for general‑purpose power applications. It combines high bulk capacitance (15,000 µF) with robust ripple‑current capability and a 105°C, 3000‑hour endurance rating for sustained operation in demanding thermal environments.

Key Features

• High Capacitance & Voltage: 15,000 µF nominal capacitance at a 25 V rated voltage, providing substantial bulk energy storage in a compact package.
• Ripple Current Performance: 3.26 A low‑frequency ripple current at 120 Hz and 3.749 A high‑frequency ripple current at 50 kHz, supporting heavy AC ripple in power stages.
• Endurance & Thermal Stability: Rated for 3000 hours at 105°C and designed to withstand 3000 hours application of rated ripple current at 105°C, enabling long‑term operation at elevated temperatures.
• Electrical Characteristics: Polarized design with ±20% capacitance tolerance (at 120 Hz, 20°C) and a tangent of loss angle (tan δ) of 0.4 at 20°C and 120 Hz.
• Leakage Current: Specified leakage current of 1830 µA (after 5 minutes’ application of rated voltage at 20°C), allowing predictable dc performance.
• Package & Mounting: φ35 × 30 mm can, radial snap‑in terminals for secure board mounting; tray packing and mass production availability simplify procurement and assembly.
• Compliance & Marking: RoHS‑compliant construction; sleeve marked with white letters on a black background for clear identification.

Typical Applications

• Power Supply Filtering: Bulk smoothing and DC bus filtering where 25 V, 15,000 µF capacitance and high ripple capability reduce voltage ripple in supply rails.
• Power Converters and Inverters: Energy storage and ripple handling in converter output stages where sustained ripple current and 105°C endurance are required.
• Industrial Power Modules: Use in industrial power modules and control equipment that demand long life at elevated temperatures and reliable bulk capacitance.

Unique Advantages

• High Bulk Energy in a Compact Can: 15,000 µF in a φ35 × 30 mm package provides substantial capacitance while conserving board space.
• Designed for High Ripple Environments: Rated ripple currents of 3.26 A (120 Hz) and 3.749 A (50 kHz) support applications with significant AC stress on capacitors.
• Long Endurance at Elevated Temperature: 3000‑hour rating at 105°C enables predictable lifetime in thermal‑stress applications.
• Clear Electrical Specs for Design Assurance: Defined tan δ (0.4 at 20°C/120 Hz), leakage current (1830 µA), and ±20% tolerance enable reliable circuit behavior and margining.
• Production‑Ready Packaging: Tray packing and mass production status streamline sourcing and assembly for volume designs.
