Learn how solar panels are made and the differences between monocrystalline, polycrystalline, and thin-film panels!
Learn about Lithium Ion Batteries, their composition, advantages, and drawbacks. https://forum.digikey.com/t/simple-undervoltage-and-overcurrent-protection-for-lithium-ion-and-lithium-polymer-batteries/13123
Learn about Printed Circuit Boards (PCBs): the essential component that connect electrical elements in devices from smartphones to satellites.
Serial communication transmits data sequentially over a single wire, advantageous for simplicity and long distances, but slower than parallel.
Wireless communication has advanced by leaps and bounds since the first devices shed their communication cables and wires. Now designers have many wireless communications options depending on their needs for range, low cost or security.
Wireless communication is dependent upon antennas of various shapes and sizes but how do they work? This video describes the basic concept of converting voltage and current into electromagnetic waves that can carry information through space between t
Pressure and Force are two terms often incorrectly used interchangeably. This video will dive into the definition of each and where they come into play.
One of the biggest threats to integrated circuits (ICs) is electrostatic discharge before, during or even after installation. This video shows how static electricity occurs and the safety standards used to reduce potential damage to sensitive compone
Pressure is the measurement of force being applied to and distributed across the surface area of an object. This video defines what pressure is and the common units of measurement. The DigiKey Pressure Conversion Calculator is also introduced.
Alternating and direct current are the most familiar ways to deliver power to our modern devices from household appliances to handheld communication.
Capacitors are one of the most popular passive electronic components you will find on nearly every circuit board. They are used to store small amount of energy and filter frequencies among other uses.
To move an object, a force must be applied. The most common unit of measurement is the Newton but is not the only unit in use around the world. DigiKey offers, among many other calculators, a tool for converting force values between popular units.
Quite often, when an electronic part becomes obsolete or is hard to acquire, a suitable substitute is available. Finding a replacement part with exact fit, form and function can be time consuming and often involves exploring offerings.
The idea of sending multiple signals through a single glass fiber would test the curiosity of any electronics enthusiast. This video explains how fiber optic cables are constructed and how signals are transmitted.
When routing traces intended to carry high frequency signals, It’s important to have a target trace impedance to preserve signal integrity. Learn how to use DigiKey’s Trace Inductance Calculator as a shortcut to manual calculations.
Most electronics experimenters have heard of or used 555 timers. You might be trying to achieve a specified output pulse but aren’t sure how to determine component values. Start with DigiKey’s 555 Timer Calculator.
Many people are familiar with a few common conversions they can estimate in a pinch. When you want to be sure and accurate, DigiKey has a full set of conversion calculators at the ready under their resource tools link.
Hydraulic and pneumatic actuators generate linear or rotational motion using a fluid under pressure, acting on a piston or vane.
