Ceramic capacitors are small, they don’t leak, they’re convenient, but they are downright strange. Certain types of caps will lose their capacitance depending on the voltage they’re operating at. If ...

Giovanni D’Amore discusses approaches to characterising both dielectric and magnetic materials using impedance analysers and specialist fixtures. We are used to thinking about technological progress ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

In the Kingston-upon-Thames museum are standard yards from the past. Made of iron, theywere the fundamental unit of length in their day. The trouble is they differ in length, some by hundreds of ...

For the makers who need to construct their own capacitors, you must choose a dielectric for it, otherwise known as the material that goes between the plates. One popular material is paraffin wax that ...

Members can download the PDF ebook. We all know that capacitors have a shunt resistance (leakage) and that leakage resistance should be pretty easy to measure, right? Wrong! I've measured a lot of ...

AVX Corporation has introduced the sub-millimeter 0201 TACmicrochip® tantalum capacitor. Measuring only 0.6mm x 0.35mm x 0.35 mm, the 0201 E case TACmicrochip Series SMD tantalum capacitors deliver ...
