Vishay has announced that it has extended the resistance tolerance of the QPL RNC90Y family of established reliability Bulk Metal Foil resistors down to ±0.005 %. For designers requiring higher or lower resistance values than the QPL range, but with the same performance capabilities, an S555 non-QPL version of the device is also available.

Omeg has added 12mm rotary encoders to its portfolio to supplement its range of 16 and 20mm potentiometers. Acknowledging the market for standard encoders is already well served, Omeg is targeting the niche market for illuminated spindle encoders. Designated the E12 Series, they are incremental, digital, 24 pulse, rotary types with conductive tracks and clear plastic 18 T splined spindles with LED illumination.

Hongfa’s HFD4 is a purpose designed, 4th generation relay available from distributor Switchtec. Meeting many international standards, the relay is one of the smallest of its type in the marketplace, and saves space in crowded telecoms PCB applications.

Intersil has introduced dual 0.5 Ohm SPST and SPDT switches featuring single supply, negative signal handling, and audio click-and-pop elimination. The combination of features and capabilities makes the ISL54062/63/64/65 series an ideal choice for battery-powered handheld products, consumer audio equipment and portable test/measurement and medical devices.

Foremost Electronics has introduced a new man-machine interface solution. The TFT128 ScreenKey is a push button switch with a built-in full colour, high resolution TFT graphics display. The display is backlit by a white LED and the integrated TFT LCD display has a resolution of 128 x 128 pixels, where each pixel colour may be chosen from a palette of 65,536 colours.

AVX Corporation, a leading manufacturer of advanced passive components and leaded solutions, has just released ‘Tantalum City’, a new CD from its Tantalum and Niobium Oxide division which is much more than a standard catalogue of parts and specs.

The THJ 200C SMD tantalum capacitor delivers 1000 hours continuous operation at 200°C with derating. Based on a unique design, distinct manufacturing processes and special ageing techniques, these capacitors guarantee high temperature performance for a variety of harsh applications such as oil drilling, aerospace/defense and automotive.

Premo has enlarged its telecoil family with the TC0502 series, a high reliability and sensitivity coil for application in hearing aids developed according to the highest quality standards - ISO/TS16949:02,ISO9001:2000).

TT electronics BI Technologies has developed a new series of thin film resistor networks. Designated the SFN Series, the networks are housed in surface mount SON (Small Outline, No Lead) packages, and are available in custom, isolated, bussed and voltage divider circuit configurations.

Providing design engineers with an ultra-stable, compact alternative to discrete resistor matched sets for high reliability divider circuits, TT electronics IRC has enhanced its SOT23 surface mount voltage divider for space-constrained applications. The new DIV23 Series voltage divider utilizes IRC’s patented self-passivating TaNFilm (Tantalum Nitride) on silicon technology and features an extended resistance range to 200K.
