What is an X-Rated Capacitor? An X-rated capacitor, also known as a line-filter capacitor or across-the-line capacitor, is a type of capacitor specifically designed and safety rated for use directly across AC power line connections or in series with the AC line. The “X” in the name refers to the […]

What are Circuit Simulators? Circuit simulators are software tools that enable users to create and simulate electronic circuits in a virtual environment. They provide a graphical interface where users can place components, connect wires, and apply input signals. The simulator then calculates the behavior of the circuit based on the […]

What is a Custom Wire Harness? A custom wire harness is a wiring assembly that is designed and built to a customer’s unique specifications rather than being an off-the-shelf product. The wire harness is custom-made based on the intended end application, performance requirements, operating environment, and other important criteria. Custom […]

What is an Arduino Battery Tester? An Arduino Battery Tester is a device that measures the capacity of a battery using an Arduino Microcontroller. The tester works by discharging the battery at a constant current and measuring the time it takes for the battery to reach a certain voltage level. […]

What are Aluminum PCBs? Aluminum PCBs, also known as metal Core PCBs (MCPCBs), are printed circuit boards that use aluminum as the base material instead of the traditional FR-4 substrate. The aluminum base provides excellent thermal conductivity, allowing for efficient heat dissipation from electronic components. This makes aluminum PCBs ideal […]
