Oscillator Circuits: The Most Important Test Procedures
Wednesday, 15 January 2020
Many engineers do not spend much thought on quartz crystals while designing their oscillator circuit. For them, it is a standard feature that will work anyway. In fact, it’s not that simple. The oscillator circuit sets the heartbeat of the application and requires a careful matching between the quartz crystal and its other components. Otherwise

No Sign of Saturation – Even After 65 Years
Wednesday, 11 December 2019
The Jauch Group has grown alongside their frequency control products and – with their early entry into the battery technology market – they are now working in two promising growth areas. “On the 65th anniversary of the company, the signs still point to further expansion,” said Managing Director Thomas Jauch. 65 years ago, Herbert Christian

Amendment to UN 38.3: Test Report for Lithium Batteries Becomes Mandatory
Tuesday, 03 December 2019
January 1st, 2020 was an important date for anyone shipping lithium cells or batteries. From that date forward, all shippers must be able to provide a test summary proving the products shipping have passed the UN 38.3 test for the transport of lithium batteries. This regulation applies to all modes of transport and it applies

Customer Success Story: Deeper’s Smart Fish Finder
Tuesday, 05 November 2019
Fishing is one of the most relaxed hobbies you can imagine. Just cast out your line and hope a fish will take the hook. Sometimes however, the angler’s patience is not rewarded and he has to return home without having caught anything. If you want to avoid this disappointment and don’t want to rely on

Jauch celebrates 65th birthday
Tuesday, 22 October 2019
65 years of Jauch – this calls for a celebration! And that’s exactly what we did last weekend at our headquarters in Villingen-Schwenningen. Around 200 guests – current and former Jauch employees with their families – did not want to miss this. After the welcome by Detlev Seiler, member of the management board, the first

How Does an Overtone Quartz Crystal Work?
Tuesday, 01 October 2019
A fast and smooth data transmission is critical in today’s world. Network and server systems are designed to process and forward information at lightning fast speeds. To achieve this, many of these applications depend on frequencies in the three-digit megahertz (MHz) range. Such high frequencies cannot be generated with an AT-crystal in the fundamental tone.

Lithium Polymer: More Safety Thanks to Ceramic Separators
Tuesday, 17 September 2019
Whether you speak of lead-acid, alkaline or lithium batteries, none of them can work without a separator which parts the positively and negatively charged electrodes. The separator prevents direct contact between the two poles and thus avoids a short circuit of the battery. It is therefore considered the essential safety feature of a cell. Even

Advantages and Special Characteristics of Lithium Thionyl Chloride Batteries
Wednesday, 04 September 2019
Lithium thionyl chloride batteries (Li/SOCl₂) belong to the lithium primary cell family. Unlike lithium ion or lithium polymer batteries, these cells cannot be recharged once they have been discharged. However, due to their long lifetime, this characteristic is of little importance in everyday use. In fact, lithium thionyl chloride batteries supply power to applications for

6 Important Parameters for the Design-In of Lithium Polymer Batteries
Friday, 02 August 2019
A standardized battery fits into any compatible compartment – after all, that’s why standards are defined. Depending on the application, however, button cells and cylindrical batteries reach their limits. A Smartwatch, for example, has a significantly higher energy consumption than an ordinary wristwatch. A simple button cell is therefore far from sufficient to cover the

The Driving Force in Electronics – A Review of 65 Years of Company History
Wednesday, 31 July 2019
Like many things that have their roots in the Black Forest, the Jauch Quartz success story begins with clocks and watches: one of the biggest hits of the 1950s, along with wrist watches and longcase clocks, was the alarm clock in a metal case. After all, no one wanted to miss out on the economic
