TT electronics BI Technologies has developed a surface mount dual winding inductor that can also be used as a common mode choke. Designated the HM78D Series, the inductor is housed in a rugged, cost-efficient package and exhibits excellent current handling characteristics.

Analog Devices has expanded its broad portfolio of digital isolation products with a family of four-channel devices that meet stringent medical-grade specifications for data and power isolation in patient monitoring and other medical equipment. Each device integrates ADI’s iCoupler digital isolation technology and proprietary isoPower dc-to-dc converter, providing both isolated power and isolated signal channels within a single package.

ATC Semitec is now stocking a range of motor protection PTCs to compliment its existing range of re-settable thermal cut-outs. The new SPMP PTCs are available with trip temperatures ranging from 60oC to 190oC and comply with the DIN 44081 industry standard.

Providing design engineers with a higher wattage device without increasing the package size, TT electronics IRC has increased the power ratings of its PWC Series resistors. IRC now offers the pulse-withstanding chip resistors in 1/2W (1206 size, increased from 1/3W); 1W (2010 size, increased from 3/4W); and 2W (2512 size, increased from 1.5W).

C&K Components has developed two new series of pushbutton switches. Designated the AP Series and HP Series, both sealed switches feature extended life cycles to 1 million and 10 million actuations, respectively.

Electronic Concepts, an Irish capacitor manufacturer, has brought out two new series of filter capacitors whose high energy density makes them a suitable substitute for electrolytic capacitors. The UP3 and UL9 series are self-healing, metallized polypropylene capacitors. The key advantages over electrolytic capacitors are a life of at least 100,000 hours at a maximum temperature of 70°C, low ESL and ESR values, a high current capability of tripl...

Providing circuit designers with a way to integrate power resistors in minimal PC board space, TT electronics BI Technologies has developed a fully customizable power resistor network. Designed specifically for power line testers and attenuators, high voltage test equipment, motor drivers with current sense circuits, snubbers and high voltage power supplies, the power resistor networks are comprised of thick film resistors on a ceramic base and f...

Avago Technologies today announced an extended temperature 2.5 Amp gate drive optocouplers for use in a wide range of industrial applications. Avago’s ACPL-312U, which is a member of the R2CouplerTM family, incorporates an alloy lead frame to offer superior heat dissipation, which allows it to operate over an extended industrial temperature range from -40 to 125 degrees C. These new extended temperature optocouplers from Avago target design...

Silicon Laboratories has introduced the Si84xx ISOpro digital isolator family, said to be the industry’s first to support as many as six unidirectional isolation channels capable of data rates up to 150 Mbps. Offering space-efficient packaging options, a choice of isolation ratings up to 2.5 kVRMS and the industry’s most highly integrated I2C isolators, the ISOpro family delivers unsurpassed system design flexibility for use in applications s...

The latest range of Metal Oxide Varistor (MOV) planar arrays from Syfer Technology are designed specifically to deliver protection against lightning strikes and other transient events in military, aerospace and other safety critical applications. Incorporated into the connectors on the external wall of the subsystem, the devices are key to protecting the increasing volume of sensitive electronic circuitry found in today’s complex systems.
