Resistors for circuit protection
In E&E Kompendium 2012, Falko Ladiges of PEMCO Product Marketing at WDI AG reports on reliable protection for circuits that enables them to function perfectly despite higher starting currents, high-voltage impulses and other overload states. Resistor circuits have long been seen as a secure, cost-effective form of circuit protection, providing controlled protection in the event of an error status.
The application determines the nature of the suppressor circuit and the resistors to be used. This means that the type of resistor (wire, metal film, metal oxide or chip) that is best able to meet the performance requirements must first be selected.

Together, we want to wrap up the automotive market!
Issue 41/2011 of Markt & Technik contains a feature on Taiwan producer TXC with whom WDI has expanded its range of clock generators for the automotive market. WDI represents the manufacturer in Europe, not just as a distributor but also as its agent with responsibility for direct customer business in the automotive sector.
Currently hovering just outside the top 3 in the world, TXC is the fourth biggest producer of clock generators across the globe. At the same time, TXC is the largest non-Japanese supplier of frequency control components to the automotive sector, giving it a crucial competitive advantage.

Specialising in quartz crystals
In the face of customers’ commercial interests and ever-increasing technological demands, the market for oscillators is becoming ever more specialised. An article in the September 2011 edition of Design & Elektronik Kompakt brilliantly illustrates this trend by citing examples from network engineering, portable applications and automotive engineering.
When it comes to newly developed oscillator technologies, it is not just about ever higher frequencies: ongoing optimisation in relation to phase noise, jitter, design and power consumption is just as important. In addition, it is becoming ever more complicated and costly to meet the requirements for the growing share of portable applications - usually the smallest designs. This explains why the market for oscillators is becoming increasingly specialised.

Quartz - a problem child?
In the 04.2011 edition of E&E, Gerd Reinhold of FCP Product Marketing at WDI AG, answers frequently asked questions about quartz crystals under the heading "True or False", offering important tips on how to ensure that crystal specifications are correct.
Because of its complexity, quartz is seen as a "diva" among components, not exactly endearing itself to developers. WDI AG is a distributor specialising in the "Frequency Control Products" market segment. As well as offering products from a wide range of manufacturers, WDI AG also provides extensive FAE support to help developers choose the right frequency generator.

Market challenger set to take off?
The 08/2011 edition of Markt & Technik takes a fresh look at the question "MEMS: yes or no?" Stefan Hartmann (Epson Toyocom), Harald Rudolph (KVG) and Christian Dunger (WDI AG), discuss the technology, performance and market prospects of the MEMS clock generators currently being heavily promoted in the media.
Bosch spin-off SiTime, financed through venture capital, started business five years ago. By offering products in the 200 kHz to 800 MHz range, this MEMS specialist now addresses almost all important segments, from consumer to industrial applications. What’s more, SiTime is now seeking to challenge quartz oscillators, tried and tested for decades in the clock-generator industry.

What to look out for in real-time-clock applications
In the 10/2011 edition of Elektronik Praxis, Roland Häni, Senior Application Engineer at Swiss-based RTC specialist MICRO CRYSTAL, and Gerd Reinhold, FCP Product Marketing at WDI AG, offer important insights into the correct and functional design of circuits, highlighting the pros and cons of various technical approaches to design.
Many applications need time and date information – from domestic appliances with a simple time display to cash machines or payment systems where the time and date are printed on slips of paper, or mobile telephones where timing data also need to be generated in standby mode.

A job for specialists
In the 02-2011 edition of the journal Medizin-Elektronik, Falko Ladiges of PEMCO Product Marketing reports on the growing market for passive electronic components in medical electronics applications.
Although the advances in medical devices are primarily due to the increasing processing power of digital systems, passive components continue to play a major role in signal acquisition and in the protection of valuable electronics. There are as many different types of resistor as there are possible applications, and they are available for a whole host of different tasks. This is explained using examples from the areas of communication, imaging and analysis.

A specialist distributor is not a niche player
In the special edition of Distribution + Dienstleistung from Markt & Technik (issue 01/2011), Christian Dunger, Board member of WDI AG, explains the special status and function of specialist distributors in the market environment dominated by broadliners.
By offering clock generators, WDI specialises in highly complex products that require a lot of pre-sales support. However, WDI doesn’t want to be pigeon-holed as a niche player, as Christian Dunger, Product Marketing FCP at WDI, explains.

Passive components and e-mechanics too
WDI AG may be seen by many of its customers as a specialist in quartz crystals and oscillators. Yet, these products only make up part of its overall product range. In the 11/2010 issue of Elektronik Industrie, Falko Ladiges (PEMCO Product Marketing) explains its large selection of highly compatible products - from classic passive components (resistors, potentiometers, and so on.) to electromechanical products (connectors, batteries, etc.).
With its extensive range of frequency-control components, WDI has gained a good reputation. So it’s easy to forget that WDI’s range of classic passive components and electromechanical components has undergone major expansion in recent years.

Resistors for smart meters
In the 10/2010 edition of Design & Elektronik, Falko Ladiges (PEMCO Product Marketing) explains how to select optimised resistors for digital electricity meters and adapt them for specific applications.
In recent years, there has been a fundamental change in the design of electricity meters, with a move away from electro-mechanical Ferraris meters. Application-specific, standard ICs available from a range of suppliers mean that commercially viable mass-market digital systems are now possible. Yet, however advanced these "smart meters" may be – they all need analogue front-end components if they are to work reliably and accurately.

Power pachyderms
In his article about thick-film heating elements in the 10/2010 issue of EL-Info, Falko Ladiges, PEMCO team leader at WDI AG, explains the technology behind them and looks at possible applications.
Thick-film heating elements ensure direct surface contact to provide optimum heat transfer exactly where it’s needed. Compact and with a flat profile, thick-film heating elements on ceramics can replace existing heating elements. As well as offering product design benefits, they are more cost-effective and require less space.
