RMAN High Power Aluminum Nitride Resistors

Stackpole Electronics RMAN High Power Aluminum Nitride Resistors are thick-film resistors built on aluminum nitride substrates for improved thermal performance. These resistors offer high power ratings of up to 3.5W with a temperature coefficient of ±150ppm/°C across a wide resistance range. Stackpole Electronics RMAN resistors operate from -55°C to +155°C and provide stability in demanding environments. These RMAN thick film resistors are RoHS and REACH compliant, halogen‑free, and suitable for high‑power applications requiring reliability and compact size.
