W1M22R0J

Through Hole Resistors

W1M22R0J is a type of through hole resistor. A through hole resistor is a metal-oxide film resistor, which contains a substrate that items and/or components can be passed through. Through-hole resistors are mounted directly to a board or to some type of mounting bracket and are available in many different ohmic values.

Application Field

Through hole resistors can be used in all types of electronic applications because of their high performance and reliability. They are commonly used in electrical and electronic equipment, including automotive, industrial, military, aerospace, medical, and communication applications. They are also used in motional feedback controls, audio and video signal processors, voltage regulators, and power supplies. Besides the above mentioned, they are also used in digital and mixed signal circuits, optocouplers, DC/DC converters, ultrasonic transceivers, and hybrid power modules.

Working Principle

The working principle of W1M22R0J is based on the PTC effect. The resistor is fabricated of a board having a high-resistivity substrate and a resistive ink that forms series interdigit interconnected stripes on the substrate. The substrate carries current between the stripes and the resistive film on the substrate reduces the current. The resistive ink on the substrate also dissipates heat, which increases resistance to further reduce the current.

In general, the working principle of through hole resistors is the same as other types of resistors; they reduce current flow through the circuit by changing the voltage. The amount of resistance is measured in ohms and is determined by the size and composition of the resistor. The resistor will generate heat when it dissipates power, but the heat dissipation is limited due to the size of the resistor. This is why through hole resistors are limited in applications requiring large amounts of current or power dissipation.

Advantages and Disadvantages

The most notable advantages of W1M22R0J are its long-term stability and environmental durability. Thanks to its robust construction, it can handle temperature fluctuations and other harsh environmental conditions without degrading. This makes it suitable for applications in extreme environments such as automotive, aerospace, and industrial applications. Additionally, it offers excellent electrical characteristics, such as low noise, fast rise time, and good linearity, and it is relatively inexpensive and widely available.

The main disadvantages of through hole resistors are its size and relatively low power ratings. Because of its size, it is not suitable for applications where space is an issue, such as in portable devices. It also has a low power rating, which limits its applications to low-power applications. Additionally, it may be susceptible to vibration, and needs to be mounted securely to a board for stability.

Conclusion

Through hole resistors, such as W1M22R0J, are metal-oxide film resistors with many advantages, including long term stability, good electrical characteristics, and environmental durability. They are suitable for a wide range of applications, such as automotive, industrial, military, aerospace, and medical applications. However, their size and low power ratings limit their applications to certain applications. As such, it is important to consider these factors when selecting the appropriate resistor.
