CBT25J4R7

Through Hole (TH) resistors, also known as Axial resistors, are among the most common types of resistors for electronic components. TH resistors are cylindrical components that have two wire leads, or contacts, that protrude from either end, making them easy to position in printed circuit boards (PCBs). The reference code CBT25J4R7 (or sometimes CBT-25J4R7) is used for a Through Hole resistor with a resistance of 4.7 Ohms and a power rating of 25 Watts; it has a wire diameter of 0.6mm and a body diameter of 8.6mm.

The way that a Through Hole resistor works is relatively simple. Electricity is able to flow easily through its two leads; however, when it passes through the resistor itself, a portion of the electricity gets "lost" in the form of heat, thus reducing the total current flowing through the two contacts. The resistor value is determined by the amount of energy (in Ohms) that is lost, and the power rating is determined by how much power (in Watts) can be absorbed without damaging the resistor.

The specific application of a CBT25J4R7 Through Hole resistor depends on its size and power rating. To maximize their effectiveness, Through Hole Resistors should be used in PCBs that are temperature-regulated, as the power wattage and resistance value of the resistor can change with temperature fluctuations. Depending on the circuit\'s specific requirements, a higher power rating can be used to increase the current handling capacity, or a lower value resistor can be used on circuits with voltage regulations of 10V or less. It is important to remember that too much power can damage the resistor and negate the effect of the resistor, so the power wattage should be selected carefully.

Beyond its use as a resistor, Through Hole resistors may be used in other capacities. A CBT25J4R7 Through Hole resistor can also be used as a voltage divider, a thermal element, or a protective device on a power supply line. Due to their small size and higher wattage rating, they are also useful for controlling the speed of motors or other mechanical systems. In all cases, however, it is important to remember that the resistance value and power wattage should be carefully considered before making a selection.

Overall, Through Hole resistors are one of the most popular types of electronic components due to their simple construction and versatility. The CBT25J4R7 Through Hole resistor is a perfect example, having a relatively high power wattage and moderate resistance value, making it suitable for many low-voltage applications. With the proper selection and proper usage, TH resistors can prove to be invaluable components in a wide variety of circuit designs.
