Through Hole Resistors

H4137KBDA resistors are among the most common through-hole resistors used in electrical and electronic circuits. The H4137KBDA resistor is a metal-oxide film resistor which is constructed from a metal-oxide film dielectric that is sputter-coated onto a ceramic body. The ceramic body helps to dissipate the heat generated within the resistor, resulting in better thermal stability compared to other types of resistors.

Application Field

H4137KBDA resistors provide superior frequency response and temperature stability compared to traditional resistors. Due to their good properties, the H4137KBDA resistors are often used for precision applications such as instrumentation, communication, and audio/video circuits. Moreover, they are also suitable for low-noise circuits, temperature sensors, and signal switches as they offer very low noise characteristics. The H4137KBDA type of resistor is also often used in the automotive industry for applications such as safety systems, security systems, and antilock braking systems.

Working Principle

The H4137KBDA type of resistor is essentially a metal-oxide film that is deposited on a ceramic body. During manufacture, the ceramic body is heated and the resistor film is sputter-coated onto the body. When the resistor is heated, the molecules of the metal-oxide film break and re-form. The re-formed molecules act as insulators, preventing electric current from passing. By adjusting the size of the molecule clusters, different resistance values can be achieved.

In operation, the resistor\'s resistance value is determined by the number of metal-oxide bonded molecules. When electric current passes through the resistor, the molecules absorb heat. This heat causes the molecules to expand, which decreases the device\'s resistance value. On the other hand, when the current is turned off, the molecules cool down and decrease in size, thereby increasing the resistance value. As such, the H4137KBDA type of resistor is capable of delivering highly stable and precise resistance values.

Conclusion

The H4137KBDA resistor offers precision, stability, and good frequency response at a reasonable cost making them a good choice for many automotive, communication, and instrumentation applications. Their low noise characteristics and thermal stability makes them suitable for a wide variety of applications. The H4137KBDA type of resistor is an effective and reliable way to control resistivity, and can be used in many different types of circuits.
