LGY1H472MELZ45

The LGY1H472MELZ45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGY long‑life series. It is a polarized, radial can capacitor specified for 4.7 mF capacitance at a 50 V rating and designed for demanding thermal and ripple environments.

Engineered for industrial power electronics, this part delivers long operational life with 5000 hours endurance at 105°C and is suited for applications such as industrial power supplies and ballast circuits where sustained reliability and ripple handling are critical. The component is RoHS compliant and intended for general purpose power applications requiring robust performance.

Key Features

• Capacitance & Voltage: 4.7 mF nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing bulk energy storage and smoothing in power rails.
• Long‑Life Endurance: Rated to withstand 5000 hours of DC bias plus rated ripple current at 105°C, meeting the LGY series long‑life assurance specification.
• High Temperature Range: Operates across –40°C to +105°C to support elevated ambient and application temperatures.
• Ripple Current Performance: Continuous ripple capability of 2.1 A at 120 Hz and 2.415 A at 50 kHz with documented frequency coefficients (e.g., 1.00 at 120 Hz, 1.15 at 1 kHz and above) for accurate thermal/ripple derating.
• Mounting & Package: Snap‑in radial can package for secure board mounting and high current applications; physical size L: 4.5 × D: 2.2 cm supports compact power assemblies.
• Leakage & Stability: Leakage current specified per LGY series limits and endurance/shelf‑life characteristics ensure capacitance stability and controlled tan δ after lifecycle and shelf stress.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for lead‑free assemblies.

Typical Applications

• Industrial Power Supplies: Bulk filtering and smoothing on input/output rails where high ripple currents and extended high‑temperature operation are required.
• Ballast Circuits: Energy storage and ripple absorption in ballast designs that demand reliable long‑term operation at elevated temperatures.
• General Purpose Power Systems: DC link or filter capacitor in general power electronics where a snap‑in mounting and robust endurance are beneficial.

Unique Advantages

• Designed for Long Service Life: 5000 hours endurance at 105°C reduces maintenance and replacement cycles in high‑temperature applications.
• Documented Ripple Capability: Rated ripple currents at 120 Hz and 50 kHz, plus frequency coefficients, enable predictable thermal and performance planning in switched and line‑frequency systems.
• Wide Operating Temperature: –40°C to +105°C operation supports deployment in harsh industrial environments.
• Secure Snap‑In Mounting: Radial can with snap‑in terminals simplifies PCB installation and improves mechanical reliability under vibration or high current conditions.
• Regulatory Compliance: RoHS compliance helps meet environmental and end‑product requirements without additional component qualification.
• High Capacitance Density: 4.7 mF at 50 V provides substantial energy reserve for smoothing and hold‑up in compact form factors.
