Through hole resistors are components which are used for various tasks in many applications. In the past, most resistors were through hole type because they were easy to manufacture and mount into the circuit substrate.

H446R4FYA is one of the through hole resistors available in the market. It is a high precision thin film resistor with tight tolerance and low temperature coefficient. This resistor consists of a thin film deposited on an alumina substrate and a Monel nickel-copper alloy metal base. It has a total of four leads, two being used for the resistance value and two for connecting to the circuit. The leads are arranged in a square pattern on the base.

The H446R4FYA have a wide range of applications. It is widely used in precision measurement and control applications such as temperature and strain measurements. The low temperature coefficient makes it suitable for these applications. It is also used in power circuits, such as in switch mode power supplies (SMPS). The low temperature coefficient of the resistor ensures a stable resistance even at high operating temperatures.

The working principle of this resistor is simple. An electric current passes through a thin film layer when exposed to an electric field. The layer acts as a resistor and the electrical resistance is dependent on the thickness of the film. By adjusting the film thickness, the resistance can be precisely tuned. This ensures that the desired resistance is achieved.

The H446R4FYA have several advantages over conventional through hole resistors. These include low temperature coefficient, high precision, wide temperature range, and low power consumption. In addition, the resistors are very small and can be easily mounted onto a substrate. Furthermore, they are cheaper than other through hole resistors.

Overall, the H446R4FYA through hole resistor is a reliable, accurate and cost effective solution for many applications. It is highly desirable for use in precision measurements and in power circuits. Its small size offered the convenience to be soldered to a substrate, and its tight tolerance and low temperature coefficient makes it an excellent choice for many applications.
