Studied to dissipate high powers in transient loads, such as those generated by inverters, snubbers, motor braking and load limiters for condensers; their very small dimensions make them ideal space saving components.


RFI resistors consist of a high resistive alloy core in a ceramic substrate, protected with a very thick case of extruded aluminium. The high quality of components excludes any possibility of smoking also in case of high loads. For application with controlled thermal state RFIT version is provided with a thermostat.


The uniformity of their surface allows RFIs to dissipate up to 4 times their nominal power, when mounted on a heatsink.



Main features

- space saving design

- wide range of transitory states
