About 18650 Batteries Pt.2 of 4 - Types and Terms

About 18650 Batteries Pt.2 of 4 - Types and Terms Some customers ask me if 18650 battery same size as AA battery? So what do these 18650 or 26650 mean? 18650 battery is different size from AA battery and they are also different types of battery. For Li-ion battery; 18 - The first two digits "18" stand for the battery diameter in millimeters. In this case width of the battery is 18mm (millimeters). 65 - The third, and fourth digit stand for length in millimeters. That would be 65mm. 0 - For…

Transformer Types

Introduction Generally a transformer is an electrical device or machine which inductively transfers the electrical power operating at a particular current and voltage of one circuit to the other circuit which is operating at different current and voltage level. Most of the transformers are manufactured such that their characteristics must match for special application requirements […]

Simple SMPS Circuit

If we need DC power supply for circuits we choose stepdown transformer based Rectifier circuit, It may give constant DC voltage under Regulator ICs but when the current fluctuations occurs at Input Power Source then the DC output supply will also gets affected. To get rid of this drawback in traditional DC power supply method engineers, electronic designers are go with SMPS circuit. You may heard the name SMPS (Switched Mode Power Supply), It gives good constant DC output with considerably…
