High Temperature MLVs and Low Capacitance MLVs Improve Auto Designs and Reliability
Multilayer varistors (MLVs) have long been an ideal solution for low power circuitry and sensor applications due to their inherent low current leakage characteristic, which can be as low as a few nanoamps. MLV off state capacitance is also a compelling advantage to designers since it provides a broad range of EMI filtering.

Femtocells: Spectrum Efficiency Improved
One of the most limited resources in telecom is wireless spectrum; therefore, it is not surprising that carriers are paying premium licensing fees for spectrum acquisition. For example, the recent 700 MHz spectrum auction in the U.S. had an aggregate bid value of $19.6 billion.

Innovation in Package-Level EMI/RF Shielding
Original equipment manufacturers (OEM) are continually looking for ways to achieve a quicker time to market when launching new products. To accomplish this, common platforms are used to keep costs down and speed up development time. The designer will standardize a majority of the individual components so they can move from one product design to another. This helps to minimize cost and improve on economies of scale. However, electrical interference cannot always be predicted between designs. This complicates the standardization of components and platforms, delaying the time to market.

Wireless Design for Regulatory Compliance
Pitfalls exist for engineers who are designing transmitters into their products. If they lack expertise in the radio technologies or if they are not familiar with regulatory constraints, their companies can easily run afoul of the law — or at least face big delays in launching new products.

How to Select the Appropriate EMI Filter for a Portable Application
The complexity of cell phones and other portable electronic equipment is continually increasing. As a result, handheld products have become far more susceptible to noise and data corruption. A quick and easy way to prevent such issues is through the implementation of EMI filters.

Sealing Electrical Connectors: When is it Worth Moving Up to Ceramic?
When engineers design a seal for feedthroughs and other electrical connectors, four general classes of material are evaluated. At the low end, a simple epoxy or glue may suffice. Alternatively, a mechanical seal with an elastomer o-ring can provide a somewhat more robust solution. For more demanding applications, glass seals are effective in preventing leakage during severe changes in temperature, pressure and humidity.

Selecting the Right Filter for Your Wireless Design
When requesting a filter, most designers fail to mention all the selection criteria. At a minimum, knowing the insertion loss across the passband, the attenuation points, the maximum size and target cost allows filter suppliers to suggest for the best filter for your design.
