Precision & Power Resistors
When you are developing a design with no tolerance for failure—whether the application will perform on the road, in the air, or the furthest reaches of space—our line of precision and power resistors deliver unequaled performance. Discover how you can meet the highest requirements in temperature coefficient of resistance (TCR), thermal EMF, long-term stability, inductance and load capacity.
Surface Mount Device
Our products set new standards for low-ohmic resistors, becoming the global benchmark in this field. Our surface mount shunts are physically optimized for current sensing and provide a range of unique benefits:
- Retain specified tolerances over the entire temperature range
- Retain specified tolerances under full power load
- Retain specified tolerances throughout the entire operating life cycle
Bus Bar Mounting
Our Bus Bar Mounting Shunts deliver a comprehensive range of high-current sensing solutions:
- Low TCR shunts constructed from Isabellenhütte's high-precision resistance alloys
- Analog sensors with integrated PCB and NTC
- Optional data matrix code (DMC) with electrical characteristic values
Hybrid Mounting
Our bondable resistors (for high-power applications) are durable and offer wide flexibility in design—with excellent heat dissipation and high load capacity. Design features extensive bonding on a conductive DBC substrate.
- Permanent power up to 20 W
- Constant currents up to 140 A
- Mounting: Reflow-, IR-soldering or bonding on substrate
- 4-terminal-connection technology
- Conductive DBC-/IMS-soldering assembly
- Nickel-plated/Au-plated bond pads
- Low resistance values
Through Hole Resistors
We offer a wide variety of through hole mounted designs that suit your most demanding applications, including high-precision resistors for laboratory applications. Several intelligent housing shapes that offer easy heat-sink mounting are available.
- Permanent power up to 20 W
- Constant currents up to 140 A
Power Resistors
Our UL-listed components are designed to support high loads (up to 3100 Watts) and high pulse rates (up to 31kW for 5 sec). Their compact size saves you space and make them easy to mount.
- Rugged Extruded Aluminum Housing
- Flying leads and tab terminals available
- IP 54 protection type
- Customizable
Aviation and Aerospace
Whenever the highest reliability, precision, and longevity are required, there is no way around the low-ohmic precision and power resistors from Isabellenhütte.
It is not without reason that we have been supplying measuring resistors to the aerospace industry for more than fifteen years.
We always meet the toughest quality standards and consider our customers’ individual requirements. In addition, the SnPb-tinned contacts avoid the formation of tin whiskers and thus short circuits in many applications.
- DLA-approved for aerospace and defense contracts
- ESCC 4001/027 and ESCC 4001/028 qualified (over 200 qualified parts)
- Dedicated production and QA for aerospace
- 100% traceable documentation and labelling
- Very good long-term stability
- Low TCR
