Providing the impulse energy capability which is normally associated with wirewound or composition resistors, the TP810 resistor uses a double-sided screen printing process of pulse-tolerant thick film ink, coupled with a sophisticated scan-cut laser trimming process, to maximise the energy withstanding capabilities.
Occupying very little PCB space, the TP810 (10 watt) is the first of a platform of high energy thick film resistors which Ohmite has designed in both radial leaded and SMD packaging. TP810 resistors are offered in 8 off-the-shelf resistance values ranging from 10-10K ohms at 5% tolerance and have been successfully tested at 100 Joules (watt/seconds) over a 100 millisecond pulse.
