Through hole resistors, or through-hole technology (THT), refer to the mounting scheme used for electronic components that involves the use of leads on the components which are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated insertion mount machines. One of the most commonly seen components that use this technology is the resistor.

CMF553K0100FKBF application field and working principle

The CMF553K0100FKBF is a resistive element that allows for a precise current limitation, providing protection to circuits from short circuits and other erratic current transients. It is commonly used in current-limiting applications such as grounding of high-power devices, and also in overcurrent protection, where a shunt resistor is used in series with a device to limit its current.

The CMF553K0100FKBF resistor features a through-hole design and is made from metal foil and epoxy, providing excellent resistance stability and excellent heat radiation characteristics. It has a power rating of 50W, a resistance value of 100Ω, and a tolerance value of ±5%. It is designed to handle peak currents up to 400A, and can withstand temperatures from -40°C to +85°C.

In terms of design, the CMF553K0100FKBF resistors use multiple metal foil layers connected back-to-back to form a resistive element. This provides excellent temperature stability and stability of the resistance value. Each metal layer is composed of a thin film of electrically conductive material with a thickness of only a few micrometers. The back-to-back layers are mounted in an epoxy encapsulated package, providing excellent environmental protection.

The CMF553K0100FKBF resistors are suitable for use in a wide range of industrial and automotive applications as well as in power supplies and lightning circuits. It can also be used for EMC protection, where it is designed to shunt noise away from sensitive circuitry, and in noise filtering applications, where it is used to filter out unwanted high frequency noise.
