New KOA WU73 Wide Terminal Flat Chip Resistors - 0612 T.C.R. ±100ppm/K

New KOA WU73 Wide Terminal Flat Chip Resistors - 0612 T.C.R. ±100ppm/K

This month KOA Europe introduces the new "Wide Terminal Flat Chip Resistors in 0612 size with T.C.R. +-100ppm/K" for Automotive. KOA’s WU73-series with its 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

The 1W power rating is double that of a standard 1206 part with terminations on the short side.

The better heat dissipation due to these wider terminals helps to save board space. The high terminal strength is due to the large soldering area. The short distance between the terminals results in significantly less expansion stress in the solder joints. KOA’s new WU73-series, available in 0612 size and in the resistance range 10m.Ohm to 100m.Ohm, is suitable for current sensing and offers a better T.C.R. compared to the standard wide terminal series.
