Protect several USB ports simultaneously with one device

TTI, Inc., the global distributor of passive, interconnect, relay & switch and discrete components, has launched new CeraDiode arrays from Epcos which are used to protect several USB ports simultaneously from static discharges, significantly reducing the PCB space and logistics costs. CeraDiodes – ceramic components developed to provide ESD protection for data, audio and video lines as well as for ICs and interfaces – are not only a cost-effective alternative to other ESD protection components such as zener and TVS diodes, but also offer technical benefits. In many cases, a semiconductor diode can be replaced by a CeraDiode on a one-to-one basis without making any changes to the pad circuit layout.

Because high data rates of up to 480Mbit/s are transmitted via the USB connection, the capacitance of the ESD protection element should be minimized in order to avoid transmission losses and signal distortions. The protection function can be realized both by single and array components, the latter being preferred for reasons of space and cost saving. The protection components must additionally satisfy the international ESD standard IEC 61000-4-2, level 4. EPCOS offers CeraDiodes as single and array components that meet these requirements precisely.

CeraDiodes are bidirectional components. As such, there is no danger of positioning them in the wrong direction. All CeraDiodes also satisfy the requirements of the international ESD standard IEC 61000-4-2 levels 1 to 4, which involves testing the components within the human body model (330Ω/150pF). The ESD protection properties of the CeraDiodes are constant up to an operating temperature of 85degC, whereas semiconductor diodes will require derating from 25degC.

Thanks to their internal electrode structure, CeraDiodes offer not only ESD protection but also have a defined capacitance, or capacitor properties. This capacitance is type-dependent and can be used for filter functions. In this way a CeraDiode can replace not only a semiconductor diode, but also a capacitor, so one component may easily replace three.

Over 1,600 lines from EPCOS now available through RS across Europe

RS Components has announced the signing of a formal global distribution franchise agreement with EPCOS AG, a worldwide market leader in a number of electronic component technologies. Since October 2009 EPCOS has been combined with the electronic components business of TDK in the new company TDK-EPC Corporation, which markets its products under the product brands, TDK and EPCOS.

Over 1,600 EPCOS products are available from RS, covering a broad range of technologies including capacitors and EMC products. The product offer is available direct-from-stock in industry-standard production packaging, at flexible quantities so customers can order the quantity they need and avoid unnecessary stock-holding costs. Customers can also achieve larger discounts when ordering higher quantities.

Commenting on the agreement, Peter Arch, EPCOS Global Sales Distribution, said: “We are delighted to have concluded this agreement with RS. Their global reach, high quality service level and focus on meeting the needs of electronic design engineers and buyers is a perfect fit with the portfolio of innovative EPCOS products. Our products focus on the fast growing leading edge technology markets, and, combined with RS’ service and support, give design engineers a compelling offer.”

For RS, Paul Webster, Head of Product Management, Electronics said: “RS is committed to giving our customers the broadest and latest offer from the world’s leading component manufacturers Our partnership with EPCOS demonstrates this commitment in action, and we are excited to be able to implement the new distribution franchise agreement.”

A wide range of EPCOS products is available online from RS at rswww.com/electronics, where customers can link straight into the product range with technical documents, then select and order direct-from-stock.

Design-in demand creation specialist to supply a comprehensive range of EPCOS’ electronic components, modules and systems

TTI, Inc., a global distributor of passive, connector, electromechanical and discrete components, has signed a Europe and North America franchise agreement with EPCOS, the worldwide market leader in a number of electronic component technologies including power capacitors, SAW components, surge arresters, thermistors, varistors and piezo actuators. In Europe, EPCOS is the top manufacturer of aluminium electrolytic capacitors, EMC components and filters, ferrites, film capacitors, and transformers and chokes. Because the agreement covers a very wide range of EPCOS’ portfolio, TTI will now be able to offer customers in Europe and North America an even broader spectrum of market-leading products.

Comments Glyn Dennehy, TTI’s Senior Vice President & General Manager Europe: “Products that have been on the market for less than three years make up about 40 percent of EPCOS’ sales. Therefore, the EPCOS franchise perfectly matches TTI’s policy of creating demand by designing-in new parts in new applications. EPCOS is a well-respected brand that stands for quality products and technology innovation. We are delighted to be able to offer EPCOS’ wide range of component solutions to our European and North American customer base.”

Adds Dietmar Jaeger, head of Global Sales Distribution for EPCOS AG: “TTI’s dedication and expertise in passive components offers us great opportunities to further grow our distribution sales in Europe and America. We are looking forward to working with their team.”

EPCOS is organized into three business segments: Capacitors and Inductors, Ceramic Components and SAW Components. With its broad portfolio the company focuses on fast-growing and technologically demanding markets, in particular in the areas of information and communication technology, automotive electronics, industrial electronics and consumer electronics.
