Below is video tutorial about automotive knock sensor. A knock sensor is basically a microphone connected to the engine block. This sensor is tuned in specific frequency. There’s a crystal inside the sensor. Knock sensor may have one or two terminal. With only one terminal, the sensor is grounded. With two terminals, one is ground, and the other is the […]

This is a video of EMI/RFI filters. This video explains about electromagnetic filters and radio frequency filters. This video also describe about consequence of the filter that is implemented on the susceptible system. The information of insertion loss and electrical characteristics of EMI/RFI filters are shown on this video. The example of EMI/RFI filters are powerline filter, power entry modules, […]

This is a RK series power line filters video. This video provide information about RK series power line filters like insertion loss information. The information about insertion loss include minimum insertion loss and maximum insertion loss. RK series power line filters can be used in many application even in high noise environment. The application that uses RK series power line […]

Below is video tutorial about electric cooling fan circuit. This circuit is consist of a fan motor, engine control module, ECT sensor, and an A/C fan control module. ECT sensor is used to sense the condition of the engine. If the engine getting hot, ECT sensor will give a signal to the engine control module to turn on the fan […]

This is a video about driving high voltage piezo actuator. Piezo electric device can convert mechanical energy to electrical energy. When converting mechanical energy to electrical energy, this device acts as sensor. Beside that, this device can also convert electrical energy to mechanical energy. When converting electrical energy to mechanical energy, This device acts as actuator. This actuator need 400V […]

This is a circuit breakers video. This video explains about circuit breakers. Circuit breakers is a electronics device that is designed to provide convenience and protection. A circuit breaker can be easily and quickly reset after it trips and the circuit fault is corrected. If a fuse blows a replacement fuse may not readily available. A breaker help to maintain […]

Below is video tutorial about Op Amp primer. Onthis following video tell us about how an Op Amp primer works. The operation of an Op Amp is very simple, just comparing 2 voltages . There are 2 inputs on Op Amp, positive input and negative input. The positive input is called as non-inverting input and the negative input is called […]
