The RSF3JT20R0 is a general-purpose current-limiting through hole resistor. It is a precision, adjustable panel mount resistor that features a mounting clip that makes contact with heat sinks and other thermal masses, providing superior thermal performance at all times. This resistor is capable of handling up to 10A continuous current. The resistor is built with a combination of fused resistor and a thermal fuse for additional over-current protection and reliability. It also features a 20-turns potentiometer for adjustable resistance. The adjustable resistance range is from 0.01Ω to 0.1Ω.
The major application and working principle of RSF3JT20R0 through hole resistor, lie in current-limiting applications. It can be used as the protection device in various circuits. Once it connected to the circuit, the current can be adjusted by a single-turn potentiometer or fitted with a tapping resistor. The device can be also used for selecting current taps, such as current trimming circuits, high voltage transformers, power supplies and many industrial control circuits.
The working principle of the RSF3JT20R0 through hole resistor is based on its thermally monitored fuse core. When a high current is applied, the core heats and melts, allowing current to pass through the resistor. Therefore, the current-limiting function will be activated and the current will be reduced to a certain safe level. If the current exceeds the specified limits, the fuse will open and shut the circuit down. This will protect electronic devices from overheating and possible damage.
The RSF3JT20R0 through hole resistor provides reliable overcurrent protection in a wide range of cases, from consumer electronics to industrial applications. Its flexibility and accuracy make it an ideal choice for current-limiting needs. It is easy to install and use, and provides high performance in all current-limiting applications.
