Power Chip Thick Film on Alumina Substrate

TA8050PA4K50FE 数据手册

  
Ohmite’s original Power Chip  
resistors feature our thick film  
on alumina substrate technol-  
ogy. These planar packages  
yield space saving, 10W/in2  
power densities that require  
over 50% less board space  
than other radial packages.  
Convection cooling is maxi-  
mized by the planar package  
configuration which dissipates  
heat well above board level.  
Ohmite’s power chip resis-  
tors have a 125% higher oper-  
ating temperature range than  
competitive product of similar  
design. High temperature  
solder and in-process plat-  
ing keep terminations secure  
under self-heating effects by  
preventing re-flow from full  
power operation.
