LGX2E471MELB25

The LGX2E471MELB25 is a Nichicon LGX series snap‑in terminal aluminum electrolytic capacitor designed for power electronics applications. It is a polarized, radial can (snap‑in) capacitor specified at 470 µF and 250 V with a compact L × D footprint of 2.5 × 3.0 cm.

Built for long‑life, high‑temperature operation, this part withstands 5,000 hours of rated ripple current at 105°C and is suited for rectifier circuits in general inverters and switching power supplies. It is RoHS compliant.

Key Features

• Electrical rating — 470 µF capacitance at 250 V nominal with ±20% tolerance, providing bulk energy storage for power conversion and filtering.
• High‑temperature long life — Endurance specified for 5,000 hours at 105°C under DC bias plus rated ripple current, ensuring sustained performance in elevated ambient conditions.
• Designed for power ripple — Rated ripple current of 1.51 A at 120 Hz and 2.265 A at 50 kHz, suitable for rectifier and switching environments that impose continuous ripple stress.
• Temperature range — Operational from −25°C to +105°C, supporting a wide range of industrial thermal environments.
• Package & mounting — Snap‑in radial can (snap‑in terminal) for secure PCB mounting and high current capability in power assemblies; physical size L: 2.5 × D: 3.0 cm.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching power supplies — Bulk and smoothing capacitor for output filtering and energy buffering in SMPS designs operating at elevated temperatures.
• Inverters and rectifier circuits — Coupling and smoothing in rectifier stages of general inverters where sustained ripple handling and long life are required.
• General purpose power electronics — Use wherever a polarized aluminum electrolytic with 470 µF/250 V and snap‑in mounting provides the required capacitance and current handling.

Unique Advantages

• Long, validated endurance — 5,000 hours at 105°C under rated ripple conditions gives designers a measurable reliability baseline for high‑temperature deployments.
• High ripple capability — Specified ripple current values at both low and high frequencies reduce the need for oversized parallel components to handle AC stress.
• Compact snap‑in form factor — Radial snap‑in can provides a secure mechanical and electrical connection suited to power PCBs while keeping board footprint small (2.5 × 3.0 cm).
• Wide operating temperature — −25°C to +105°C range lets the part be used across diverse industrial environments without derating for typical ambient swings.
• RoHS compliance — Meets current RoHS directives for materials, simplifying regulatory compliance in commercial products.
