SMD Resistors – Introduction and Working
Resistors which are based on SMT technology are called SMT resistors which are one of the members of the SMD family or surface mount device family. By: S. Prakash The electronic equipment of various types such as televisions, commercial communication equipment, cell phones, research equipment of high technology and MP3 player uses the SMD resistors. […]
Types of Thermistors, Characteristic Details and Working Principle
The thermistor name has been devised as a short form for the “thermally sensitive resistor”. The full form of the thermistor provides the general and the detailed idea of the action which is the feature of the thermistor. By: S. Prakash The various different types of the devices in which the thermistor are used include […]
Understanding Color Codes of Resistors with Practical Examples
In this post I will comprehensively explain regarding the various standard resistor color codes, and systems employed for assigning resistors their specific values. The post also explains how to read and identify resistor values from their color codes. By: S. Prakash The color codes used in resistors denote a leaded resistor’s value. These color codes […]
How to Identify Component Specifications in Schematics
In this post I have explained the correct way of understanding and identifying component specifications in a given circuit schematics, even if the details are missing in the document or the schematic. Schematics without Part Specifications When a new hobbyist searches for a particular electronic circuit of his choice, the internet provides him with a […]
Schottky Diodes – Working, Characteristics, Application
Schottky barrier diodes are semiconductor diodes designed with minimal forward voltage and fast switching speeds which may be as low as 10 ns. These are manufactured in current ranges of 500 mA to 5 amps and up to 40 V. Due to these features they become specifically suitable in low voltage, high frequency applications such […]
