LGX2G271MELC25

The LGX2G271MELC25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series, offering 270 µF capacitance at a 400 V rated voltage. It is a smaller‑sized, long‑life unit designed for power electronics where high temperature endurance and robust ripple handling are required.

Typical use cases include rectifier circuits for general inverters and filtering in switching power supplies. The component combines a compact radial, can‑style package with long life assurance and RoHS compliance for industrial and general‑purpose power designs.

Key Features

• Electrical performance — 270 µF capacitance at 400 V rated voltage with ±20% tolerance (measured at 120 Hz, 20°C); polarized design for DC power applications.
• High temperature long life — Endurance specified as 5000 hours at 105°C under rated ripple current and DC bias, with capacitance change within ±20% and leakage current within initial specified value after test.
• Ripple current capability — Rated ripple currents include 1.22 A at 120 Hz and 1.745 A at 50 kHz, supporting demanding filtering and rectifier duties in power stages.
• Wide operating range — Specified for operation from −25°C to +105°C, suited to elevated ambient conditions encountered in power electronics.
• Low‑temperature stability — Impedance ratio Z(−25°C)/Z(+20°C) is covered by LGX series limits for the 400 V range, supporting predictable behavior at cold starts.
• Mounting and package — Snap‑in terminal, radial can package in a compact footprint (approx. L: 2.5 × D: 3.5 cm), enabling robust PCB mounting for power assemblies.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General inverter rectifiers — Used in rectifier circuits to smooth DC output and handle high ripple currents in inverter front‑ends.
• Switching power supplies — Bulk and smoothing capacitor for switching supplies where high ripple endurance and elevated operating temperature are required.
• General purpose power electronics — Filtering and energy storage in industrial and commercial power modules that benefit from long‑life 105°C performance.

Unique Advantages

• Proven long‑life specification — 5000 hours endurance at 105°C under rated ripple and bias ensures predictable life performance for sustained high‑temperature operation.
• Compact, serviceable package — Snap‑in radial can with a smaller footprint (L: 2.5 × D: 3.5 cm) offers a space‑efficient solution for dense power boards.
• High voltage and capacitance combination — 400 V rating with 270 µF capacitance provides substantial energy storage for high‑voltage DC link and bulk filtering tasks.
• Measured ripple ratings — Specified ripple current at both low (120 Hz) and high (50 kHz) frequencies supports designers optimizing for real‑world switching environments.
• Industry compliance — RoHS compliance supports regulatory requirements for commercial and industrial products.
