RESISTORS CAPACITORS COILS DELAY LINES
Typically half the size of conventional resistors! Type 202 is
world’s smallest wirewound resistor! Series 200 resistors
offer the same MIL-grade construction as Series 100 resistors
except utilize proprietary materials and processing, enabling
significant size reductions. Series 200 resistors are ideal
when PCB real estate is at a premium! Highest grade
materials enable excellent stability and environmental
performance.
DERATING: Power resistors reach elevated temperatures when
operated near full wattage, and therefore should be mounted
off the PCB and derated according to required stability levels.
