The KOA Speer RK73H2BTTD39R0F is a 39Ω thick film chip resistor in the 1206 imperial case size (3216 metric), with a 1% tolerance and a 100ppm/°C temperature coefficient. It carries a 250mW power rating and a 200V DC working and voltage rating, measures 3.2mm by 1.6mm with a 600µm height, and has two SMD terminations. The RK73H2BTTD39R0F is AEC-Q200 rated and operates from -55°C to 155°C. It is recorded as RoHS compliant and lead free, with China RoHS Non-Compliant and REACH SVHC recorded as Yes.

Low-value precision resistors around 39Ω are used for series termination on digital lines, gate drive damping on MOSFETs, snubber networks and current limiting in driver and interface circuits. AEC-Q200 qualification means the part has been stress-tested to the automotive passive component standard, so it is specified for engine and body control modules, ADAS sensors, lighting and infotainment as well as industrial equipment that borrows automotive reliability requirements. The 1206 case size gives a higher power rating and voltage standoff than the smaller 0603 and 0402 sizes at the cost of board area. Buyers should note the China RoHS Non-Compliant and REACH SVHC flags recorded against this part when checking programme compliance.
