TYPICAL SIZE COMPARISON

Ω
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.
