Through Hole Resistors support a range of values and can accommodate a range of power requirements, from small form factor (SFF) through larger sizes. They are both linear and non-linear devices, which means they are suitable for many applications in which properties such as temperature stability, power ratings, and the precision of the resistance value are crucial. One such device, the H475KDZA, is a through-hole resistor developed and produced by Murata Manufacturing Company.

Application Field

The H475KDZA is a device designed for through-hole mounting in industrial, automotive, and consumer electronic applications. The most common uses for this resistor include power supplies, motor drives, overcurrent protection, and displays. It is particularly suitable for applications that require excellent electrical properties, such as temperature stability and very accurate resistance values. In addition to through-hole applications, the H475KDZA can also be used in reflow soldering processes and offers good robustness in lead-free solder.

Working Principle

The H475KDZA is a non-inductive chip resistor, available in a wide array of values from 0.1 ohm to 5 megaohms. It is made up of a ceramic substrate, metal electrodes, and between them an inner thin-film resistor. The two metal electrodes can be either an aluminum or nickel, depending on the customer\'s requirement. The aluminum electrode provides good temperature stability and low TC, whereas the nickel film electrode provides excellent electrical and thermal stability.

The H475KDZA is also notable for its high insulation resistance, which can reach up to 10^12 ohms. This provides good performance even in high frequency applications, when the resistance is essential for grounding purposes. With a wide variety of resistance values and power ratings to suit various applications, the H475KDZA is an extremely versatile resistor.

In addition, the H475KDZA features a low heat dissipation coefficient, which helps to ensure safety even at high power conditions. The resistor is also designed with precise tolerance, so that the actual resistance value differs only slightly from the specified value.

In summary, the H475KDZA is an ideal resistor for a range of applications in both through-hole and reflow soldering processes. Its excellent electrical, thermal, and insulation properties make it suitable for high power applications, while its various resistance values and power ratings offer many options for different applications.
