The first in a platform of new high energy thick film resistors from Ohmite is now available from TTI, a leading specialist distributor of passive, connector, electromechanical and discrete components. The Ohmite TP Series offers the benefits of non-inductive performance and high power density in a compact design to save PCB space. These thick-film resistors also provide the impulse energy capability normally associated with wire wound or composition resistors. Double-sided screen printing of pulse-tolerant thick film ink on an alumina substrate and an advanced scan-cut laser trimming process maximizes the energy withstanding capabilities of this new series. The first parts to be released are known as the TP810 (10 Watt) resistors, offered in eight off-the-shelf resistance values ranging from 10 Ohms to 1 million Ohms at 5% tolerance. They are available in radial leaded and SMD packaging and are easy to install and PC mountable. Further features include high-temperature terminal construction (solder plated phosphor bronze), high power density and low inductance of 50nH - 100nH. Thermal conductivity is 20 Watts/Meter/degC. Maximum operating voltage is 350VAC, 500VDC through glass and 1000VAC, 1500VDC through substrate. The TP Series is fully RoHS compliant. TTI
