V. High-Power Resistor Selection Guidelines
-
Power Margin: Actual operating power should not exceed 50% to 70% of rated power, leaving adequate thermal headroom.
-
Pulse Capability: Frequent switching scenarios require attention to short-term overload capacity and pulse energy withstand ratings.
-
Thermal Management: SMD high-power resistors require large copper areas or thermal vias; wirewound types need assured heat dissipation at the mounting surface.
-
Precision and TCR: Current sensing applications should prioritize metal foil or alloy resistors (TCR below ±50ppm/℃); standard power divider applications may use thick-film solutions.
-
Certification Requirements: Automotive electronics must confirm AEC-Q200 qualification; military and aerospace applications require attention to MIL-PRF-55182 and similar standards.
