Product Description
RK73H Precision Thick Film Chip Resistor
The RK73H series is a precision thick film chip resistor featuring a protective coating, inner electrode, resistive film, and ceramic substrate. It offers excellent heat resistance and weather resistance due to its metal glaze thick film construction. Suitable for both flow and reflow soldering, these resistors meet EU RoHS requirements for lead-free terminations. The series is AEC-Q200 tested across a wide range of sizes from 01005 to 2512.
