As electronics enthusiasts we may come across many kinds of resistors, from small fixed resistor to high current bulk rheostat. There are humongous classifications among resistors, but here we will focus on a particular kind of resistor called “flex resistor” and learn how it works. As the name signifies a flex resistor is flexible and […]

Transistor Stray pickup False Triggering Problem
In this article I have explained how to make any BJT or mosfet based circuit free from stray signal pickup and false triggering by simply attaching a filter resistor or a capacitor across their base/emitter or gate/source terminals. The problem was raised by Mr.Henrik. Solving a Circuit Problem I have an issue I don’t understand. […]
High Voltage Transistors BUX 86 and BUX 87 – Specifications
In this article we are going to make an effort to understand the technical specs of the BJTs BUX86 and BUX87 which are high voltage complementary paired transistors. Introduction The Bux 86 and BUX 87 are typically high voltage switching transistors with silicon epibase. They come in TO-126 package and are NPN types. These devices […]
BEL188 Transistor – Specification and Datasheet
The transistor 188 is one of my favorites, simply because even being so tiny it’s able to handle currents as high as 1 Amp. Understanding BEL188 Transistor Specification/Datasheet The transistor BEL188 is a general purpose transistor, and due to its wide voltage and current rating can be used for almost all small to medium power […]
