Ask The Engineer: How Are Quartz Crystals with A Frequency Tolerance of only +/- 10 ppm produced?
Wednesday, 29 May 2019
Basic tone crystals with high frequencies are in great demand, especially for wireless applications in the Internet of Things industry. More and more often we find devices communicating with each other and exchanging data via radio, for example via Bluetooth, ZigBee or ISM. All these radio standards use frequency bands in the three-digit megahertz or

Jauch Crystals in Electric Racing Car
Friday, 17 May 2019
Sized at just a few millimeters, quartz crystals are probably ranked highest among the inconspicuous electrical components. Although hardly any electronic application could operate without these components, even engineers often see them as a minuscule detail. However, Jauch’s support of the “GreenTeam” at the University of Stuttgart demonstrates the importance of quartz crystals in the

Why Do Tuning Fork Crystals Always Have A Frequency of 32.768 kHz?
Wednesday, 27 March 2019
The tuning fork crystal as it is used in watches is something like the “classic” among the quartz crystals. Its frequency is always exactly 32.768 kHz. But why this value? The answer to this question can be found in the history of quartz crystals. Bell Telephone Laboratories, the former research department of today’s telecommunications group

Stable Frequency at Variable Supply Voltage – Jauch Presents New Oscillators
Wednesday, 06 March 2019
If you want to equip your product with an oscillator, and there is hardly an electronic application that can do without, you must define the operating voltage of your application first because oscillators are usually “calibrated” to a specific voltage value. A precise frequency requires a constant and predetermined working voltage. If deviations occur, the

A World without Frequency Control Products– Unthinkable!
Wednesday, 26 September 2018
“Frequency control products have become indispensable in our daily lives. Without them, we would not be able to tell the exact time, the washing machine would not know when the laundry is ready, and in traffic, we could not safely turn left because the turn signal would not work. We are proud to be able
