How can you clarify specific frequency range for the classifications?

Latest Updated:03/01/2006

Question:

The data sheet indicates that some products are for low-frequency amplification or some are for high-frequency amplification; how can you clarify the specific frequency range for these classifications?

Answer:

There is no strict classification, but low-frequency elements are generally for amplification in the several tens of hertz to several tens of kilohertz frequency area, i.e., the range used in audio and musical instrument applications.
High-frequency elements are assumed to amplify signals in the range of several tens of kilohertz to several hundred megahertz.
Incidentally, elements that amplify signals of 1 GHz or higher are known as ultra-high frequency elements.
