Powerfilm™ Surface Mount Resistive Products

API Technologies designs and manufactures resistive surface mount devices that include both thin-film and thick-film technology available in chip, leaded, or flange-mount packages. These surface-mount devices include legacy designs from the former KDI business unit as well as Inmet rod resistors. The new Powerfilm™ brand surface-mount resistive components from API Inmet are enhanced to include even more reliability, options, frequency, and power than ever before. Employing a proprietary proven and economical thick/thin film processing approach, these resistive components are optimized for your high-power signal conditioning, leveling, gain optimization and matching network challenges.



  • Frequency Performance up to 27 GHz
  • Power Ranges up to 1250 Watts
  • Standard Attenuation Ranges up to 30 dB
  • Standard Ohm Values from 5 to 300 Ohms
  • Wide selection of flange and cases footprint sizes varying from .020"x.040" to 1.900"x1.000"
  • Chip wrap configurations optimized for power, frequency or surface-mount applications
  • Gold, Silver, tin-lead and lead-free tinned finishes are available for most parts
Powerfilm chip attenuators from API Inmet come in two varieties: "Temperature Stable" (standard) and "Temperature Variable" attenuators.
Powerfilm flange attenuators are designed to uniformly reduce power of the RF signal while generating only a small reflection even under maximum power conditions.
API Technologies offers a wide selection of Powerfilm chip terminations. These surface-mount resistive components allow for RF power dissipation in terminations and isolators.
API Technologies offers a wide selection of Powerfilm™ flange terminations.
API offers a wide selection of Inmet Brand Powerfilm™ chip resistors. These surface-mount components allow are often used in hybrid attenuators and Wilkinson power dividers.
Powerfilm flange resistors are used in power generators, attenuators, or stripline and microstrip hybrids.
API Inmet Powerfilm™ product line includes a selection of passive resistive components designed for use with stripline circuits.
API Technologies offers a wide selection of Powerfilm™ Rod Resistors.
