TA Series Power Chip Resistors
The Ohmite Power Chip Resistor is a thick film resistive ink resistor. These resistors are lightweight, economical, non-inductive, have high power density and require minimal
board space. It is constructed on an alumina substrate with copper plated silver conductors, ruthenium oxide resistance material, and a glass passivation layer. The resistors have
very low inductance of 50 nH measured at 1 MHz. The thin profile and low inductance are specifically designed for switch mode power supplies. Repetitive transient withstand
capability is 5 times peak as long as the one second average dissipation remains equal to or less than rating. Terminals are solder plated brass. Additional values available.

Ceramic housing for fiberglass or metal oxide core with cement based filling. Tolerance: 5%. Short time overload (10x rated
wattage for 5 sec.; metal oxide 5x rated wattage for 5 sec.) results in ±2%. Derate linearly from 100% @ 70¡C to 0% @
275¡C. Incombustibility at 16x rated wattage for 5 min. is not flamed. Additional values available.
