Through Hole Resistors provide a significant advantage in high power applications, due to their ability to dissipate heat in an efficient manner. The CMF7025R000DHEB is a particularly noteworthy through-hole resistor design, enabling a significant current flow at high power levels due to its novel construction. This device is particularly suited for applications that rely on high-power stability, such as in automotive, military, or industrial electronics.

CMF7025R000DHEB Application Field

The CMF7025R000DHEB is a high-power through-hole resistor designed for applications that require high power stability, such as automotive, military, and industrial electronics. Thanks to its large size and superior contact technology, this device is especially well-suited to applications involving extremely high current levels. It provides a maximum power rating of 750W in a 2512 size. Despite its hefty dimensions, the CMF7025R000DHEB features a surprisingly low mass of only 2.2 grams.

CMF7025R000DHEB Working Principle

The CMF7025R000DHEB is a surface mount technology device, meaning it utilizes contact technology to maintain the desired operation. Specifically, this resistor utilizes a metallized substrate material as a contact surface. This enables excellent heat dissipation, as a greater surface area is present for heat dissipation than if a single contact point were used for power dissipation and thermal stability. This metallized substrate also facilitates low inductance, as opposed to through-hole resistors which suffer from increased inductance penalties due to the length of the hole.

Further, the metallized substrate of the CMF7025R000DHEB also provides a durable base for overall operation. This material resists environmental changes such as vibration, temperature, and humidity, providing a highly reliable operational performance despite environmental interference. Lastly, the material also helps reduce the contact resistance, meaning that current flow is better maintained than if a standard through-hole resistor were used.

In addition to the unique contact technology, the CMF7025R000DHEB also features a customizable terminal insert, allowing for greater power density. This terminal insert is made out of an alloy material, providing excellent dimensional stability and electrical characteristics. The terminal insert also features a thermal pad, which helps to reduce any resistive dissipation due to thermal expansion.

Conclusion

Overall, the CMF7025R000DHEB is a superior through-hole resistor design, capable of providing exceptional performance at high power levels and in hostile environments. Its metallized substrate and customizable terminal insert make it well-suited for applications such as automotive, military, and industrial electronics, enabling higher current levels and greater stability overall.
