Through Hole Resistors

Through hole resistors are components consisting of a resistor embedded in a cylindrical enclosure. They are commonly used in electronic circuits to limit current, to provide bias voltage, and to attenuate signal levels. Through hole resistors are available in a wide range of resistance values, ranging from as low as a few ohms up to several megohms. Compared to surface mount resistors, through hole resistors are more robust and have higher power ratings.

SFR16S0004532FR500 Application Field and Working Principle

The SFR16S0004532FR500 is a through hole resistor specifically designed for use in automotive electronics. It is a non-inductive, low-profile, axial-leaded device housed in a resin-coated, anti-corrosive stainless steel package. Its construction includes a high-purity alumina substrate coated with a thick-film resistive coating. The resistor also has an internal humidity sensor connected to the substrate. The SFR16S0004532FR500 is rated for operating temperatures between -40°C and +135°C with a maximum operating voltage of 500 V.

The working principle of the SFR16S0004532FR500 is based on the principle of resistive heating. When a voltage is applied across the resistor, a current will flow through it which causes the resistor to heat up. As the resistor heats up, its resistance increases, limiting the current and protecting the circuit from overloading. The SFR16S0004532FR500 also has a humidity sensor which helps to ensure accurate and reliable measurement of the resistor\'s actual resistance in high-humidity or wet environments.

The SFR16S0004532FR500 is suitable for a wide range of automotive electronics, including audio and video systems, navigation systems, engine control modules, information and entertainment systems, as well as lighting applications. In addition, the SFR16S0004532FR500 is suitable for general purpose applications in industrial, medical, and consumer electronics. Its low profile and robust construction make it ideal for applications where space is at a premium.

In summary, the SFR16S0004532FR500 is a high-performance through hole resistor suitable for a wide range of automotive electronics, industrial, medical, and consumer electronics applications. It is designed for high temperatures, humidity, and voltage, and its low profile makes it suitable for space-limited applications.
