FCR3WSJT-73-390K

Through Hole Resistors are a type of resistor with two electrical terminals used in electrical and electronic circuits. The name "through hole" comes from the fact that the resistor is inserted into a physical hole in the circuit board and soldered to the traces on either side. FCR3WSJT-73-390K is such kind of Through Hole Resistors. This article describes its application fields and working principle.

The FCR3WSJT-73-390K Through Hole Resistor is primarily used in automotive, consumer, industrial and medical applications where high power, low thermal resistance and superior environmental resistance are required. It is available in an axial lead design and has an operating temperature range of -55°C to +150°C. The resistor has a power rating of 390k, a resistance tolerance of ±5%, and an NTSC tolerance of 3%. The resistor also has an additional feature of a self-healing property that helps to reset itself when there is an overload.

The FCR3WSJT-73-390K Through Hole Resistor is designed using Metal Foil Technology (MFT). MFT is a method of manufacturing resistors by laminating a thin metal film between two layers of ceramic substrate and then attaching the resistive film to low-cost etched carbon conductor. The resistor provides consistent stability and reliability over wide operating temperature conditions and superior noise reduction. Additionally, the FCR3WSJT-73-390K offers improved heat dissipation compared to other conventional Through Hole Resistors for extended life cycles.

The FCR3WSJT-73-390K Through Hole Resistor is designed to provide superior performance. The resistor composition consists of a resistive element with two electrical terminals and a non-conductive ceramic substrate. The resistive element can be either a thin layer of metal foil or a thin film of carbon. It is then attached to the substrate with a dielectric bond. The two current terminals are connected to the resistive element and the electrical contact is made via the metal leads attached to each terminal pad. This ensures reliable connections for the full range of current ratings.

The FCR3WSJT-73-390K Through Hole Resistor has other features as well. Its low noise technology reduces unwanted electrical noise from the environment. Additionally, it is RoHS compliant and has a high-temperature performance. The resistor also has additional features such as high pulse wave form capability and high surge capability.

In conclusion, the FCR3WSJT-73-390K Through Hole Resistor is designed for high power, low thermal resistance and superior environmental resistance applications. It has a power rating of 390k, a resistance tolerance of ±5%, and an NTSC tolerance of 3%. The resistor offers reliable connections, low noise, RoHS Compliance and high-temp performance. It also has a self-healing property that protects against overloads, making it the ideal choice for a wide range of applications.
