UCS2G100MPD

The UCS2G100MPD is a miniature aluminum electrolytic capacitor from Nichicon's UCS series. It is a radial-lead, polarized can capacitor designed for high ripple current and long life in compact power applications.

Targeted at power supply and ballast applications, the UCS2G100MPD delivers a 10 µF capacitance at a 400 V rating with RoHS compliance, making it suitable where elevated temperature endurance and compact footprint are required.

Key Features

• Capacitance & Voltage: 10 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing stable bulk energy storage for high-voltage circuits.
• High Ripple Current Handling: Rated ripple currents of 175 mA at 120 Hz and 350 mA at 100 kHz support applications with significant AC superimposed on DC.
• Long Life at Elevated Temperature: Engineered for extended operation at high temperature—rated for 8000 hours at +105°C for this package size.
• Temperature Range & Reliability: Operates from −40°C to +105°C, suitable for demanding thermal environments within that range.
• Compact Radial Can Package: Radial lead (5 mm lead spacing) can-style package with dimensions L: 2 cm × D: 1 cm for a small PCB footprint and through-hole mounting.
• Polarized Design: Polar electrolytic construction for use where polarized capacitance is required.
• RoHS Compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements for restricted substances.

Typical Applications

• Power Supplies: Bulk filtering and smoothing in high-voltage power supply rails where high ripple current capability improves thermal performance.
• Ballasts and Lighting Drivers: Designed for ballast applications referenced in the UCS series description, providing long life under continuous load.
• Industrial Power Modules: Compact energy storage and decoupling in industrial converters and power conditioning circuits operating up to +105°C.
• General-Purpose High-Voltage Circuits: Through-hole, radial-lead mounting for robust connections in repairable or mechanically demanding assemblies.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings at both 120 Hz and 100 kHz allow designers to size capacitors by frequency-specific stress.
• Elevated-temperature endurance: Rated for 8000 hours at +105°C for this package size, providing predictable lifetime in hot environments.
• Small footprint: 2 cm × 1 cm can reduces PCB area compared with larger high-voltage capacitors while maintaining high-voltage capability.
• Radial-lead mounting: Through-hole radial leads simplify assembly and mechanical retention for applications that benefit from robust soldered or hand-soldered connections.
• Regulatory compliance: RoHS compliance supports designs that require restricted-substance conformance.
