LGX2E561MELB30

The LGX2E561MELB30 is a snap‑in terminal aluminum electrolytic capacitor designed for power electronics where high operating temperature and long life are required. It delivers 560 µF at 250 V in a compact radial can with snap‑in mounting, intended for general purpose power applications such as rectifier circuits in inverters and switching power supplies.

Key value propositions include long life assurance at elevated temperature (5,000 hours at 105°C under rated ripple current), RoHS compliance, and design‑friendly electrical characteristics including defined ripple current ratings and low leakage behavior.

Key Features

• Construction / Package — Aluminum electrolytic, radial can with snap‑in terminals for secure PCB mounting and robust mechanical retention.
• Rated Capacitance & Voltage — 560 µF nominal capacitance with ±20% tolerance, rated for 250 V DC and polarized operation.
• High‑Temperature Long Life — Endurance guaranteed for 5,000 hours at 105°C with DC bias plus rated ripple current applied; capacitance change, dissipation factor and leakage current meet specified limits after test.
• Operating Temperature Range — Specified for −25°C to +105°C operation.
• Ripple Current Capability — 1.83 A at 120 Hz and 2.745 A at 50 kHz, supporting high‑frequency and low‑frequency ripple handling in power supplies.
• Electrical Losses — Dissipation factor (tan δ) max 0.15 at 120 Hz, 20°C for rated voltages in the 200–400 V range (applies to this 250 V part).
• Low Leakage Characteristic — Leakage current governed by the datasheet specification I ≤ 3√(C·V) (µA) after 5 minutes at 20°C, enabling predictable standby and filtering behavior.
• Size — Compact dimensions approximately 3 × 3 cm, with a seated height of up to 1.181 inches, suitable for space‑constrained power modules.
• RoHS Compliance — Conforms to RoHS requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Power Stages — Bulk and smoothing capacitance for rectifier circuits in general inverters where elevated temperature endurance is required.
• Switching Power Supplies — Input/output filtering and energy buffering in switching supplies, leveraging the rated ripple current at both low and high frequencies.
• General Power Electronics — Decoupling, smoothing, and energy storage in industrial and commercial power systems that require polarized electrolytic capacitors with long life at 105°C.

Unique Advantages

• Proven High‑Temperature Endurance: 5,000‑hour endurance at 105°C under rated ripple current gives predictable life performance in hot operating environments.
• Dual Frequency Ripple Ratings: Specified ripple current at 120 Hz and 50 kHz supports designs that must handle both mains‑frequency and high‑frequency switching ripple.
• Predictable Loss and Leakage: Defined tan δ and leakage current specifications enable accurate thermal and reliability calculations during design and qualification.
• Space‑Efficient Snap‑In Packaging: Snap‑in radial can simplifies PCB mounting for higher current applications while minimizing board real estate.
• Regulatory Compliance: RoHS conformity supports environmental and regulatory requirements for commercial and industrial products.
