Through Hole Resistors are a very common component found in electrical and electronic circuits. The CMF551M5000DHEB is a through-hole, single turn high-power ceramic resistor, offering superior operating temperature performance and durability.

It is composed of two major parts, the outer body and the ceramic core. The body is made from positive temperature coefficient (PTC) or negative temperature coefficient (NTC) ceramics. The ceramic core is made of a nickel chromium alloy, with a unique octagonal cross-section, designed to provide excellent heat transfer.

The CMF551M5000DHEB is really designed to offer superior operating temperature performance and durability in industrial applications. It has a relatively low resistance range between 0.8Ω to 1KΩ. Key features of the resistor include high operational temperature range from -55°C to 350°C, low resistance tolerance (1%), wide operating frequency range (up to 4.0GHz), and the ability to handle up to 10 Watts of power. These characteristics make it especially suitable for use in high frequency and high power applications.

The main advantages of a through hole resistor are their low cost, general performance, and relative ease of assembly. Its low profile design also allows for space saving on the printed circuit board for efficient wiring and assembly. Since the resistor has a relatively low resistance range, it can be used as a replacement for smaller surface-mount resistors in some cases.

In terms of applications, CMF551M5000DHEB is designed primarily for industrial and automotive applications. It can be used in consumer electronics products as well as medical and military applications. It is also used in industrial power supplies, heaters, inverters, motor controllers, automotive electronics, DC/DC converters, and any other electronic component that requires high power or high operational temperature.

The working principle of the CMF551M5000DHEB is relatively straightforward. It works by using a ceramic body and core, along with a nickel chromium alloy, to help dissipate heat. As the resistor’s temperature rises, its resistance decreases, which reduces the amount of current passing through the component. This helps protect other components in the circuit from overheating, which could cause them to fail.

In conclusion, the CMF501M5000DHEB is a through hole resistor commonly used in industrial and automotive applications. Its unique octagonal cross-section offers superior heat transfer capability and its relatively low resistance range makes it a great replacement for smaller surface mount resistors. With a high operational temperature range, low resistance tolerance, and wide operational frequency range, it is perfect for use in high power and high frequency applications.
