Why Choose a BeO Ceramic Substrate?
Beryllium oxide ceramic is prized in RF and microwave engineering for its exceptionally high thermal conductivity — far superior to standard alumina ceramics. This allows the resistor to efficiently dissipate heat during high-power operation, maintaining stable electrical characteristics over extended use. The flange mount design further aids heat transfer to a heatsink or chassis, making this component ideal for both bench testing and integrated RF system builds.
Typical Applications
- RF transmitter dummy load during testing and tuning
- Power termination in microwave circuits (DC–3 GHz)
- RF lab and bench test setups
- Amplifier load testing
- Impedance matching and termination networks

Frequently Asked Questions
Q: What is the maximum frequency this 100W flange mount resistor supports?
A: This flange mount RF resistor is rated for use from DC up to 3.0 GHz, making it suitable for a broad range of RF and microwave applications including transmitter dummy load testing and power termination up to that frequency range.
Q: Why does this resistor use a BeO ceramic substrate instead of standard alumina?
A: Beryllium oxide (BeO) ceramic offers significantly higher thermal conductivity than standard alumina ceramic. This means the resistor can handle 100 Watts of continuous power more effectively, dissipating heat faster and maintaining stable resistance values — critical in high-power RF dummy load applications.
Q: Is this resistor compatible with the RFP-100-100RW-S cross reference?
A: Yes. This 100W 100 Ohm flange mount resistor is a compatible cross-reference for the RFP-100-100RW-S and RFP 100-100 part numbers, as well as the RFR100-100 designation, making it a convenient drop-in replacement for qualifying designs.
Q: What mounting style does this resistor use?
A: This component features a flange mount design, which allows it to be bolted directly to a heatsink, chassis, or enclosure wall. This not only secures the resistor mechanically but also facilitates efficient heat dissipation during high-power operation.
