High Precision Metal Film Flat Chip Resistors is One Size Smaller than Before

2024.09.18

To achieve higher rated power by terminal temperature regulation

RN73H

KOA's metal film flat chip resistors RN73H(for Automotive, High Reliability) and RN73R (High Reliability) have expanded the rated power based on the revised terminal part temperature specifications.
The rated power of all sizes from 0402 inch to 1210 inch has been increased, such as guaranteeing a rated power of 0.25 W for the 0805 inch size, which is 2 times higher than that of the conventional one.
RN73H/RN73R can now be used in 1 size smaller than before while maintaining high precision.(Example: 0603 inch to 0402 inch)
AEC-Q200 Tested.

Applications:
Automotive electronics, industrial equipment, measurement equipment,etc.
