Thick Film High Power Chip
Resistors and Terminations
on Aluminum Nitride
The
ims
N-Series thick film high power chip resistors and chip terminations on
aluminum nitride are ideal for most applications requiring high thermal conductivity in
a small size package. AlN is an ideal replacement for BeO with it’s high power
dissipation and no enviromental or health hazards. Thick film technology provides a
stable resistive element at a very affordable price. These chips feature the following:
• High stability thick film resistive element
• AlN substrate material
• Operating temperature: -55°C to +155°C
• Available in bulk or tape and reel*
*Consult factory

A Word About Thermal Management
temperature of the chip is maintained at or below the values identified in the above table
and the maximum film temperature did not exceed 150°C. The data also shows that the
ratio of temperature rise versus power applied increases with increasing chip size (for a
given thickness) so the above criteria should be carefully considered when operating
host of circuit dependent parameters.
