TYPICAL SIZE COMPARISON
2W carbon composition
2W wirewound (standard)
2W wirewound (type 210)
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.
