Through hole resistors are resistors that are constructed in such a way that they are mounted in a printed circuit board using leads. This type of resistor is used primarily in prototyping for quick design cycles, prototype testing and debugging. The use of these resistors in the circuit board guarantees a low cost and very reliable connection when compared to other forms of resistors.

A particular through hole resistor that is popular in circuits is the PTF653K4990AYBF. This type of resistor is made of carbon film, which is capable of withstanding an operating temperature of 125°C and ensures reliability and durability. It has 4 terminals located at equal distances from each other. A 4 terminal resistor eliminates the need to connect multiple resistors in order to obtain the desired resistance level. The terminal pins are made of brass and can be configured to different sizes based on the need.

The PTF653K4990AYBF through hole resistor is most commonly used in switching circuits, power supplies, and audio power amplifiers. It is also often used in signal conditioning, high voltage applications and in specific temperature sensing applications. It is constructed with a temperature coefficient of –6 ppm/°C, which means that the resistor value will remain the same even with temperature changes. This makes this resistor ideal for use in circuits where exact values are required.

The working principle for the PTF653K4990AYBF through hole resistor is based on the Ohm’s Law which states that the resistance is equal to the voltage divided by the current. The resistor is designed to limit the current flow through the circuit so that it will operate in a safe and reliable manner. This resistor works by dissipating the electrical energy as heat, instead of allowing all of the energy to pass through the circuit, it will absorb some of it.

The PTF653K4990AYBF through hole resistor is a reliable and affordable option that can be used in electronic circuits to regulate the voltage or current. It is typically used in audio and power circuits where accuracy and stability is critical. Its ability to withstand up to 125°C makes it suitable for use in applications where elevated temperatures are present. Its use in the circuit guarantees higher reliability and accuracy thanks to its tight tolerances and temperature stability.
