New Ferrite Suppressors from Leader Tech for Snap-On Shielding Solutions
Tampa, FL — Bisected FerriShield Ferrite suppressors from Leader Tech are available in a wide assort- ment of styles and sizes and can quickly be snapped onto a cable that has already been terminated. The company offers hundreds of frequen- cy-specific ferrite solutions for both round and flat cables. On a daily basis, there are mil-
lions of electronic devices that oper- ate in close proximity on a very nar- row portion of the wireless communi- cations spectrum that spans from 30Hz to 300GHz. Due to antenna size, power, range, cost constraints and stringent FCC regulations, most of our personal electronics crowd an even a smaller portion of that spec- trum (5GHz and below). Therefore any uncontrolled electromagnetic
Diodes Inc. Introduces Automotive Rectifiers
Plano, TX — Diodes, Inc. has intro- duced a family of its Super Barrier Rectifiers (SBR®) qualified to the AECQ101 high-reliability automo- tive standard and backed by PPAP level 3 documentation. The parts are 100 percent avalanche tested and proven to deliver a reverse-ava- lanche capability of between three to 10 times greater than competing Schottky alternatives. Due to the SBR’s patented
structure, its high-reverse avalanche performance ensures greater guard- banding against negative spikes and inductive load surges, thereby rais- ing the ruggedness and reliability of automotive products. In a typical single-pulse avalanche test, ava- lanche energy measurements for Schottky and SBR devices were respectively 7mJ and 70mJ for the same circuit conditions.
radiation in this frequency range can interfere with the normal operation of your electronic device. Control of
electromagnetic and radio frequency interference (EMI/RFI) is a major engineering concern for all electron-
ics manufacturers. Unfortunately, many of these problems are not known until the costly, testing stage of development. In many instances, it is discovered that a data cable or even power cord is acting as an antenna, causing unacceptable levels of interference to spill into the envi- ronment. One of the easiest and most
cost-effective solutions for this type of shielding problem is to attach a ferrite suppressor to the origination and/or termination ends of your cables.

SBR automotive rectifiers. Offering current ratings up to
60A and reverse voltage ratings up to 100V, the SBR “Q” portfolio is also characterized by significantly lower reverse leakage current at higher temperatures, helping to minimize circuit losses and increasing protec- tion against thermal runaway. The SBR forward voltage drop
is also lower than that of the Schottky, meaning conduction losses are less and overall efficiency is improved in common reverse-polari- ty protection and freewheeling diode circuits.
