LGX2E102MELB40

The LGX2E102MELB40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series designed for high‑temperature, long‑life power applications. It provides 1 mF capacitance at a 250 V rating in a compact radial can with snap‑in mounting, optimized for rectifier circuits in inverters and switching power supplies.

Built for continuous operation up to 105°C and rated to withstand 5000 hours of rated ripple current at that temperature, this component targets general‑purpose power electronics designs that require robust ripple handling and long service life.

Key Features

• Capacitance & Voltage — 1 mF nominal capacitance with a 250 V rated voltage and ±20% tolerance, suitable for bulk filtering and energy storage in high‑voltage power rails.
• High‑Temperature Long Life — Endurance rated for 5000 hours at 105°C under DC bias plus rated ripple current, supporting extended reliability in thermally demanding environments.
• Snap‑in Mounting, Radial Can — Snap‑in terminal type in a radial can package for secure PCB retention and straightforward insertion in power assemblies.
• Operating Temperature Range — Specified for −25°C to +105°C to accommodate a wide range of ambient conditions in industrial and power electronics equipment.
• Ripple Current Capability — Rated ripple current of 2.33 A at 120 Hz (low frequency) and 3.495 A at 50 kHz (high frequency) to support rectifier and switching environments.
• Polarized Electrolytic — Polarized construction for DC applications where large capacitance per volume is required.
• RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
• Compact Footprint — Physical size approximately L: 4 × D: 3 cm with a seated height up to 1.575 inch, offering a smaller footprint for high‑capacity solutions.

Typical Applications

• Switching Power Supplies — Bulk filtering and smoothing on the DC bus to reduce ripple and stabilize output voltages in power converters.
• Inverter Rectifier Circuits — Energy storage and ripple handling on rectifier outputs for general inverter applications.
• Industrial Power Electronics — High‑temperature, long‑life capacitor for motor drives, power modules, and industrial converters where extended endurance is required.

Unique Advantages

• Long‑Life at Elevated Temperature — 5000‑hour endurance at 105°C under rated ripple current reduces periodic replacement and maintenance in hot enclosures.
• High Ripple Handling — Specified ripple current at both 120 Hz and 50 kHz supports performance across rectifier and switching frequency regimes.
• Secure Snap‑In Mounting — Snap‑in terminals provide mechanical stability on PCBs in vibration‑prone or assembly‑intensive environments.
• Compact, High‑Capacitance Solution — 1 mF capacitance in a smaller can footprint enables designers to meet energy storage requirements without excessive board area.
• Regulatory Compliance — RoHS compliance supports deployment in regions and products requiring restricted substance controls.
