Key Features

Low ESL <10nH
Compact terminal arrangement
Low ESR <0.20 mOhms
High RMS current capability >400 Arms
Integrated mounting flange to withstand high
shock and vibration environment

Next generation inverter application

The UNLYTIC ® LH3 series film capacitor has been designed utilizing Lo-Henry™ technology. It is a coaxial film technology that produces very low inductance (ESL). With an effort to keep overall system costs down, the LH3 series was designed with a compact terminal layout. It will allow designers to reduce the overall buss bar dimensions.

The capacitor is encapsulated in a specially formulated potting compound that will enhance the overall thermal capabilities of the capacitor. The LH3 series is housed in a high strength thermoplastic designed to withstand high shock and vibration environments.

Performance Characteristics

Dielectric Strength

Capacitors withstand a DC potential of 1.3 x rated voltage for one (1) minute without damage or breakdown. 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 2.1 x 10-4 over the operating temperature range of -55°C to +105°C and frequencies to 1MHz.
