Through Hole Resistors

The H447R5BYA is a through-hole resistor with long term stability and reliability. It belongs to the H447R, CLR Series of thick film resistors, and its installation is made by soldering. This resistor is available with a range of values from 1.5ohm to 1Mohm, with power ratings up to 500mW and a 0.1% resistance tolerance.

The H447R5BYA is constructed from a highly stabilized ceramic substrate material, using electrical conducting processes based on flame and/or organic and inorganic material deposition. The electrical properties of the resistive film are determined by the composition of the resistive layer, which is composed of carefully selected conducting particles and binders. This resistive layer is then protected by ceramic coatings for improved heat and environmental resistance.

Application Field

The H447R5BYA resistor is ideally suited for applications requiring precise control over the power dissipated in the resistor, such as in power supplies, audio and power amplifiers, as well as for digital circuits. Its long-term stability and reliability make it the ideal choice in demanding applications, such as automotive, telecommunications, and aerospace.

The wide range of values makes it suitable for different DC circuits, including precision measuring instruments, radio receivers, digital integrated circuits, and even laser systems. Its excellent tolerance makes it the perfect candidate for applications where accuracy is paramount, such as power supplies and medical equipment.

Working Principle

The principle of operation of the H447R5BYA is based on electrical conduction. This type of resistor increases the voltage or current typically applied to the material, causing electricity to flow through it. This flow of electricity creates an electric field, which results in a resistance to current. The resistor\'s value is determined by the size of this electric field.

The resistor is constructed with a ceramic substrate material, on which a resistive layer is applied. This layer is composed of various conducting particles and binders. The electric resistance these particles offer is determined by their physical characteristics, such as surface area, electrical conductivity, and temperature coefficient. This resistive layer is protected by a ceramic coating, making the resistor highly resistant to heat, humidity, and environmental factors. The electrical characteristics of the resistor are determined by the resistive layer composition.

Apart from its excellent electrical properties, the H447R5BYA is also highly reliable and long-term stable, making it the ideal choice for demanding applications. Its wide range of values and accuracy make it suitable for a variety of DC circuits.
