.Introduction to Through Hole Resistors
Through hole resistors are electronic components typically used in applications where a low resistance value is required. They are one of the most common and widely used types of resistors. Through hole resistors are often used in circuits as they can be more reliable than surface mount devices. CFR2WSJT-73-3R Application Field and Working Principle
CFR2WSJT-73-3R is a through hole resistor designed for critical applications. It is a high voltage, high current, and metal oxide film type. This type of resistor offers excellent stability over temperature, with minimum power ratings of 100W. It has an operating temperature range from -55°C to +175°C, and a rated voltage range from 0.3W to 600V. Furthermore, it has a power coefficient of 1%.In terms of its working principle, when a current is applied to a through hole resistor, some amount of the current is diverted through the resistor. The amount of current diverted through the resistor is determined by the resistance rating of the resistor. Generally, higher resistance ratings will lead to higher levels of current being diverted through the resistor. The amount of power that the resistor dissipates depends on its power rating. The amount of current that the resistor can handle is determined by its maximum heat dissipation rating.Advantages of Through Hole Resistors
One of the main advantages of through hole resistors is their size. Because of their small size, they can offer a large amount of electrical resistance in a very small package. This makes them ideal for applications where space is a concern. Through hole resistors are also relatively cheap. They are also easier to handle compared to surface-mount devices, as they can easily be soldered to the board by hand.Through hole resistors also have excellent temperature stability. Because they do not use wirewound technology, they are not prone to shifts in resistance levels due to temperature changes. This is ideal for circuits that require a very consistent resistance level.Disadvantages of Through Hole Resistors
The main disadvantage of through hole resistors is their size. Due to their small size, they are not suitable for high power applications. They also require a hole to be drilled in the circuit board for installation. This can be a time-consuming and costly process.In addition, through hole resistors have a limited power rating. If the circuit requires more power than the resistor is capable of handling, then a larger resistor must be used.Conclusion
Through hole resistors are an essential components for many electronic applications. Their small size and low cost make them ideal for low power circuit designs. They also offer excellent temperature stability, which makes them suitable for circuits that require consistent levels of resistance. CFR2WSJT-73-3R is a through hole resistor designed for critical applications. It has a high voltage and current rating, and offers excellent stability over temperature. It also has a power coefficient of 1%, which ensures accurate operation.Overall, through hole resistors can be very advantageous when integrated into a circuit design. While they do have some disadvantages, their numerous advantages should not be overlooked.
