LGU1E273MELC

The LGU1E273MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, offering 27,000 µF capacitance at a 25 V rating. Designed for general-purpose power applications, it provides high ripple-current handling and extended endurance for demanding thermal environments.

Key attributes include a wide operating temperature range of −40°C to +105°C, a rated lifetime of 3,000 hours at 105°C, and compact dimensions (φ35 × 45 mm), supplied in tray packing for production use.

Key Features

• Capacitance & Voltage — 27,000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, suitable for bulk energy storage and smoothing.
• High Ripple Current Endurance — Low-frequency ripple current of 4.75 A (120 Hz) and high-frequency ripple current of 5.463 A (50 kHz), enabling effective filtering under sustained AC loading.
• Long Life at Elevated Temperature — Endurance specified as 3,000 hours at 105°C with rated ripple current applied, supporting reliable operation in high-temperature systems.
• Thermal Range — Rated for operation from −40°C to +105°C, covering a broad set of industrial and commercial environments.
• Low-Frequency Dissipation (tan δ) — Measurement condition at 20°C, 120 Hz; series specification lists tan δ maximum of 0.40 at 25 V.
• Leakage Current — Specified leakage current of 2,460 µA (after standard preconditioning), allowing designers to budget for standby and quiescent currents.
• Form Factor & Mounting — Snap-in radial can (φ35 × 45 mm) for secure board mounting and straightforward assembly; packaged in trays for production handling.
• Compliance — RoHS compliant per manufacturer declaration.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling in DC power supplies where high capacitance and sustained ripple capability are required.
• Industrial Power Electronics — Energy buffering and ripple suppression in inverters, motor drives, and control panels operating up to 105°C.
• Energy Storage for Rail and Hold-up — Short-term energy hold-up and transient support where large capacitance and dependable endurance matter.

Unique Advantages

• High Ripple Handling: Rated ripple currents of 4.75 A (120 Hz) and 5.463 A (50 kHz) reduce heating and improve filtering performance under real-world AC stress.
• Proven High-Temperature Endurance: 3,000-hour rating at 105°C provides predictable lifetime behavior for thermal-constrained designs.
• Large Capacitance in a Compact Can: 27,000 µF in a φ35 × 45 mm package helps minimize board area while maintaining bulk energy storage.
• Production-Ready Packaging: Tray packing supports automated handling and assembly for volume production environments.
• Clear Electrical Parameters: Specified leakage current and tan δ at standard test conditions help designers estimate losses and thermal impact precisely.
