Key Features
- Inductance as low as 25nH (less than 12nH available)
- Low ESR
- Current carrying capability to 152 amps
- Withstands hostile environments
- Integrated mounting flanges
- RoHS compliant
- Operation to 125°C
- Acts as drop-in replacement for state-of-the-art polypropylene DC technology
Home > Film Capacitors > UX3 Series
The UX3 Series is the first drop in replacement for traditional designs to meet the demand of high temperature applications at 125°C. Maintaining the same mechanical envelope as the UL3 Series, the UX3 Series out performs at higher operating temperature range and current carrying capability.
Whether you need performance at 125°C or higher current capability at 105°C, the UX3 Series is the solution.

Dielectric Strength
Capacitors withstand a DC potential of 1.3 x rated voltage for one (1) minute without damage or break down. Test voltage is applied and discharged through a minimum resistance of 100 OHM per volt minimum.

Dissipation Factor
Polypropylene has an intrinsic dissipation factor of less than 2.1x 10-4 over the operating temperature range of -55°C to +125°C and frequencies to 1MHz.
