MO,MM Series: An inexpensive replacement for commercial wirewounds.
HV Series: High voltage, high value metal oxide resistors.
E Series: Thick and thin film surface mount resistors, general purpose and precision.
BW Series: Fusable - Failsafe.
WW Series: Our commercial precision wirewound resistor, equivalent of the military RW series.
CB or TCB Series: A general purpose production-type power resistor.
PC Series: Specially designed for use on printed circuit boards.
VM Series: This is a CB type of resistor in a vertical mount package.
WP Series: Our ultra precision wirewound line for extremely tight TCs and tolerances.
KAL Series: The "brute strength" resistor of the wirewound line.
MR Series: A molded ribbon resistor made for very low resistances to be used at extremely high frequencies.
SM Series: A general purpose power wirewound surface mount resistor..
TP or TS Series: Extremely low ohmic values.

*For extended range parts (higher than those shown) please call factory.
**Temperature coefficients shown are the standard minimums for these parts at mid and high values. Low value resistors have a slightly higher TC. Please call factory with any special TC requirements.
