Electronic components list: a comprehensive guide
If you are electronics enthusiastic, engineer or student, a completely electronic components list is required. This guide covers almost all running electronic components, providing a valuable resource for circuit design, troubleshooting and learning. This post is highly informative.
What is an electronic component list?
An electronic component list is a detailed list of parts used to create repair or design electronic circuits. These components are broadly classified into active, passive and electro-mechanical categories.
Classification of electronic components
1 -Passive Components
Passive components do not require external energy to operate and cannot amplify signals. The most common passive components include:
Resistors (fixed, variable, network, Thermistors, Photoresistors)
Capacitors (ceramic, electrolytic, film, tantalum, mica, variable)
Inductors (air core, iron core, ferrite core, variable, toroidal)
Transformers
Crystals and Oscillators
Filters (low-pass, high-pass, band-pass, band-stop)
Fuses
Varistors
Ferrite Beads
Mechanical Switches (toggle, push button, rotary, DIP, slide, micro, reed)
Relays (when used purely for switching without amplification)
Circuit Breakers
Connectors (headers, sockets, terminal blocks, PCB connectors)
Sockets (IC sockets, relay sockets)
Printed Circuit Boards (PCBs) (as passive interconnects)
Buzzers/Horns (when not powered, act as passive sounders)
Energy Storage Devices (such as super capacitors, though these are a type of capacitor, sometimes listed separately)
Memristors
Networks (RC, LC, or RLC networks for filtering and timing)
Heaters (resistive heating elements)
Resistance Wire/Nichrome Wire (used for heating or current limiting)
Humistors (humidity-dependent resistors)
Transducers (when not powered, such as piezoelectric buzzers in passive mode)
Varactors/Varicap Diodes (used as voltage-dependent capacitors in RF circuits)
2 -Active Components
Active components can amplify, switch, or generate signals. The core active components in any electronic components list are:
Diodes
Rectifier diode
Zener diode
Schottky diode
Light Emitting Diode (LED)
Laser diode
Photodiode
Varactor diode
Tunnel diode
Transistors
Bipolar Junction Transistor (BJT)
Field Effect Transistor (FET): MOSFET, JFET
IGBT
Phototransistor
Darlington transistor
Thyristors (SCR, TRIAC, DIAC, UJT)
Integrated Circuits (ICs)
Operational Amplifiers (Op-Amps)
Logic Gates (AND, OR, NOT, NAND, NOR, XOR, XNOR)
Microcontrollers
Microprocessors
Timers (e.g., 555 Timer)
Voltage regulators
Memory chips (RAM, ROM, EEPROM, Flash)
Analog/Digital Converters (ADC/DAC)
Programmable Logic Devices (FPGA, CPLD)
Display Devices
7-segment display
Dot matrix display
LCD, OLED, LED displays.
3. Electromagnetical Components
These are components that combine electrical and mechanical processes:
Switches (toggle, pushbutton, rotary, DIP, micro, limit, reed, slide)
Relays (electromechanical, solid-state)
Connectors (headers, sockets, terminal blocks, PCB connectors)
Potentiometers and Rheostats
Motors (DC, stepper, servo)
Buzzers and Piezoelectric DevicesMicrophones and Speakers
4. Sensors and Other Components
Modern circuits often include sensors and other specialized components:
Temperature Sensors (thermistors, RTDs, thermocouples)
Light Sensors (LDR, photodiode, phototransistor)
Proximity Sensors (inductive, capacitive, ultrasonic)
Pressure Sensors
Humidity Sensors
Accelerometers and Gyroscopes
Gas Sensors
Current and Voltage Sensors
Hall Effect Sensors
Infrared Sensors
Touch Sensors.
