referenssikäämiä
Referenssikäämiä, known in English as a reference coil or standard inductor, is a type of inductor specifically designed for high precision and stability. It is used in metrology and scientific instrumentation as a standard for inductance measurements and in the calibration of other inductance measuring devices. The key characteristic of a referenssikäämiä is its ability to maintain a very stable inductance value over time and under varying environmental conditions such as temperature and humidity.
The construction of a referenssikäämiä typically involves a carefully wound coil of wire on a low-loss, dimensionally
Referenssikäämiä are employed in a variety of applications requiring precise inductance values. This includes their use
