H875RBCA

Application Field of H875RBCA

H875RBCA is a high-precision controlled negative temperature coefficient (NTC) through hole resistor for reliable electronic temperature control and temperature compensation. This type of resistors is mainly used in applications such as temperature measurement, temperature compensation circuits, and thermal protection. It is designed with precision resistors, multiple metal shields, and low temperature coefficient substrate to offer superior accuracy and reliability.

H875RBCA is ideal for temperature measurement and thermal protection in automotive and industry as well as industrial communication systems. It also provides a more accurate reading of temperatures in high current, high voltage, and high frequency applications. H875RBCA is also extensively used in automotive engines, where the material is proven to be reliable and stable. Additionally, the very low noise output ensures that H875RBCA is suitable for applications were low noise requirements are necessary.

Working Principle of H875RBCA

The basic working principle of H875RBCA is thermal protection, temperature measurement, and temperature compensation. It works by using materials that have a low temperature coefficient of resistance to measure temperatures in a predefined range. When the temperature exceeds this range, the resistance value changes accordingly. The negative temperature coefficient of the material allows the resistor to decrease its resistance with an increase in temperature. The resistance helps to regulate the temperature within a certain range even if the temperatures outside of that range are encountered.

The main components of H875RBCA include the substrate, the resistor, the shielding, and the thermal protectors. The substrate material is designed to provide insulation and to protect the resistor from external influences. The resistor is the main heating and cooling element while the shielding helps to protect the resistor from external electromagnetic interference. The thermal protectors are used to detect excessive temperatures and to disconnect the resistor from the circuit.

In summary, the H875RBCA is an ideal choice for temperature control, temperature sensing, thermal protection, and temperature compensation due to its high precision, reliability, and low temperature coefficient. Its low noise output and low on-resistance ensure that this through hole resistor can be used for applications where noise requirements are stringent.
