Optocouplers, Part 1: Principles and usefulness

By

The optocoupler — also called an optoisolator — is among the most useful, versatile, problem-solving components available to the design engineer. This small non-monolithic device does one thing and does it well, with minimal complications in most cases and no software. This FAQ will look at its operation principles, key parameters, and applications of this […]

Getting started in electronics: core components

By

By “Spec“, Electro-Tech-Online forum member Often newbies ask, ‘How can I get started in electronics?‘ This is a big question, but the very short answer is, ‘Learn the two fundamental electronics laws (Kirchoff, Ohm), get a good book about electronics theory and practical, build some circuits, and make some measurements.’ Follow-on questions are, ‘What electronic […]

High-power precision shunt resistors incorporate bulk metal foil technology

By

The VPG Foil Resistors product group of Vishay Precision Group announced the global market launch of the Alpha Electronics FNP Series, a family of high-power precision shunt resistors. Design of the Alpha Electronics FNP Series incorporates VPG’s own proprietary Bulk Metal Foil technology for a low-temperature coefficient of resistance (TCR) down to 0±1 ppm/°C, depending […]

The neglected resistor characteristics

By

We often take resistors for granted. They are one of the fundamental building blocks of electronics design but are often given little thought when choosing them. You will select a value and the tolerance, and probably briefly consider the power dissipation and provided that isn’t very high you will most likely be picking all your […]
