Frequently Asked Questions
How much power can TKH45P10R0FE-TR continuously dissipate in a surface-mount design?
TKH45P10R0FE-TR is rated for 45 W continuous power dissipation. The TO-252 package measures 12 mm × 8.3 mm with a 0.91 mm body height, allowing efficient board-level heat spreading when mounted to a suitable PCB copper area or thermal pad.
What resistance value and package style does TKH45P10R0FE-TR use, and how does that affect circuit design?
The part provides a 10 Ω resistance in the TO-252 surface-mount package. At 45 W rated dissipation, this resistor can handle up to approximately 2.1 A continuous current, making it suitable for snubber networks, braking resistors, and current-limiting stages in industrial motor drives.
Is TKH45P10R0FE-TR supplied in a reel format compatible with automated SMT placement?
Yes. TKH45P10R0FE-TR ships on a 13-inch tape-and-reel, which is compatible with standard pick-and-place equipment. The TO-252 footprint has 3 pins and a 2.28 mm pitch, so it integrates directly into existing SMT assembly lines without manual placement.
Which industrial or automotive applications benefit most from this 45 W TO-252 resistor?
Motor drive braking circuits, DC-DC converter snubber networks, power supply pre-load resistors, and automotive auxiliary power modules all benefit from TKH45P10R0FE-TR. Its 45 W rating and compact 12 mm body make it a strong candidate where high power density and board-level mounting are required at the same time.
