RMAN Thick-Film High-Power Aluminum Nitride Substrate Chip Resistors

Stackpole thick-film high-power chip resistors deliver exceptional power density while maintaining performance

Image of Stackpole RMAN Thick-Film High-Power Aluminum Nitride Substrate Chip ResistorsThick film chip resistors on alumina substrates have long dominated the market due to their balance of performance, stability, reliability, and cost. However, alumina’s limited thermal conductivity restricts the power levels these resistors can achieve. The Stackpole RMAN series overcomes this constraint by utilizing aluminum nitride substrates, which offer significantly higher thermal conductivity. This advancement enables substantially greater power-handling while maintaining the performance and reliability customers expect from thick-film resistor technology.

The RMAN series delivers exceptional power density with ratings of 2.4 W in a 1206 package and 3.4 W in a 2512 package. These power levels are achieved while keeping hot-spot and terminal temperatures within safe operating limits – performance difficult to achieve with conventional alumina-based high-power chips.

Features
  • Thick-film technology on aluminum nitride substrate
  • High power ratings
  • High reliability, high stability
  • Tolerances 1% and 5%
  • TCR: 150 ppm
  • RoHS and REACH compliant and halogen-free
