A fixed resistor is a two-terminal passive component that is used to implement electrical resistance like a circuit element. The flow of current throughout this resistor is directly proportional to the voltage supply across the two terminals of this resistor. So, this relationship can be simply s...
The complete resistor is encapsulated within a layer of insulating resin. The tapered section of the resistor facilitates direct mounting with an aperture in a circuit card. Soldered connections may be made to the connecting strips. The metal oxide film may be secured onto the substrate either ...
Metal film resistor metal film resistor symbol RJ as a mark Metal film resistors are one of the film resistors (Film Resistors). It uses high-temperature vacuum coating technology to closely attach nickel-chromium or similar alloys to the s...
1.3.1 Direct PWM Mode Operation For Direct PWM operation, the POSx and NEGx pins must be connected to the circuit in either of the configurations shown in Figure 1. If the sense resistor is included, the load current can be monitored by the microcontroller via a SPI command. The open ...
and have an accurate overpower protection, an offset proportional to the input voltage is added on the CS signal by turning on an internal current source: by adding an external resistor in series between the sense resistor and the CS pin, a voltage offset is created across it by the current...
