Increased Power Ratings for WU73 and WK73 Wide Terminal Resistors (AEC-Q200 qualified)

As a result of rigorous temperature testing, development and evaluation, the power rating for several wide terminal chip resistor series has been increased. KOA’s wide terminations SMD resistors now allow the designer to use a higher power rating for chip sizes 0612, 1020 and 1225.

The 90° rotated design offers several advantages compared to standard resistor footprints, such as:
- Higher reliability in power applications
- Improved terminal strength
- Lower expansion stress
- Lower temperature rise
- PCB space saving

Features
- Higher power than conventional style types
- Excellent heat dissipation characteristics
- Superior temperature and power cycling performance
- AEC-Q200 qualified

Applications
- Automotive, including ‘under the hood’ applications such as ECUs
- Power supplies
- DC-DC converters
- Motor controls
- Industrial power controls
- Battery packs
- Consumer electronics
