| Electronic Terms | Basic description | RF Wireless World Reference |
|---|---|---|
| BJT | It stands for Bipolar Junction Transistor. BJT is a current controlled device. It has three terminals emitter, base and collector. | BJT |
| FET | It stands for Field Effect Transistor. FET is a voltage controlled device. It has three terminals Source, Gate and Drain. | FET |
| Diac | Made of 2 zener diodes interconnected back to back. | Diac |
| Triac | made of two SCRs connected in parallel and in opposite direction. | Triac |
| JUGFET | Full form is Junction Gate FET. | JUGFET |
| MOSFET | Full form is Metal Oxide Semiconductor FET. | MOSFET |
| Electrolytic capacitor | The device used to store charge in its metal body with polarity is referred as Electrolytic capacitor. | Electrolytic Capacitor |
| capacitor | The device used to store charge is referred as capacitor. There are many types of capacitor depending upon the application. | Capacitor basics |
| Inductor | 线的线圈有或没有被称为核心as inductor. When current is passed through it, magnetic field is generated. It has reactance which equal to 2*pi*f*L , hence at higher frequency, impedance will be higher and it will be able to block the frequencies. DC or low frequency will be easily passed through due to lower impedance. | Inductor basics |
| Transducer | The device which converts one form of signal to the other form is referred as transducer. For example, microphone, speaker, sensors etc. are transducers. | Transducer |
| Microphone | Microphone is a type of transducer which converts acoustic signal into the electrical signal form. | Microphone types and basics |
| Thermistor | The device whose resistance changes with temperature is referred as thermistor. | Thermistor |
| Relay | The type of switch operated by magnet is referred as relay. It can be made on or off based on passing current through it. | Relay |
| Reed Switch | It is also type of switch used for fast switching applications in telephone line exchanges. | Reed Switch |
| Battery | The device used to provide DC power. Mainly used to power the mobile phones, tablets, laptops etc. | Battery |
| SCR | The full form is Silicon Controlled Rectifier. | SCR |
| Op-AMP | Operational amplifier(OP-AMP) is used in many applications due to its high gain, high input and low output impedances. | OP-AMP |
| Transformer | It converts AC voltage from one value to the other value. This is achieved with two coils having different number of turns referred as primary and secondary coils. | Transformer basics and types |
| Resistor | The device which dissipates power when current is passed through it. It basically provides resistance to the flow of current and hence limits the current. | resistor basics |
| Variable resistor | The resistor whose resistance value can be changed manually or through software is referred as variable resistor. | Variable resistor |
| Variable capacitor | The capacitor whose capacitance value can be changed is referred as variable capacitor. | Variable capacitor |
