Through Hole ResistorsThrough hole Resistors are the commonly used type of resistors used in electronics to limit the flow of electric current. The RN55C3903CRE6 is a precision, chip type, through hole resistor, used in various applications within the electronics industry.RN55C3903CRE6’s primary application fields are in low-frequency amplifiers, audio and communication equipment, and voltage regulation systems. The resistor is constructed from a resistive element, an insulating substrate, and a casing. When a voltage is applied to the resistor, the resistive element turns the voltage into heated energy. This energy is then dissipated through the casing and substrate, resulting in the controlled flow of electric current through the resistor.The RN55C3903CRE6 is a highly precise resistor, with tolerance levels of 0.05%, so it can produce accurate current and voltage regulation when used in electrical circuits. The resistor features a three-layer structure that includes an insulated substrate, a conductive resistive film, and a terminal. The resistive film can be constructed from a variety of materials, depending on the application, including metal alloys, carbon, and silicate.The RN55C3903CRE6 also has high temperature stability, making it suitable for use in arduous environmental conditions. The resistor has a temperature coefficient of resistance (TCR) of just ±50 ppm/°C, meaning it can retain its precision even at extreme temperatures. This makes it ideal for use in industrial and automotive applications that require consistent current regulation, no matter what the ambient temperature is.In addition to the RN55C3903CRE6’s functions, that resistor is also available with a range of options. These include an oxide-filled resistive element, a coated substrate, an insulating substrate, and a hermetically sealed casing. This allows for further precision and capability to match specific requirements for each application.In summary, the RN55C3903CRE6 is a versatile and highly precision through-hole resistor suitable for use in low-frequency amplifiers, audio and communication equipment, and voltage regulation systems. With its strong temperature stability and high precision, the resistor is perfect for applications where reliable current regulation is necessary. It is also available with an array of optional features, including an oxide-filled resistive element, coated substrate, insulating substrate, and hermetically sealed casing.
