Vishay has announced a new ultra-high-precision Bulk Metal Foil four-resistor network that offers excellent load life, load life ratio, and shelf life stability characteristics. The hermetically sealed new SMNH resistor network features a load life stability of 0.005 % at 0.1 W per resistor at + 70 °C for 1000 hours and a load life stability ratio of 0.005 % (50 ppm).

Vishay has introduced the new PNM series of precision non-magnetic thin film resistors. The devices feature a low standard TCR of ± 25 ppm/°C and laser-trimmed tolerances down to ± 0.1 % over a wide temperature range of - 55 °C to + 125 °C.

Designed for accuracy and economy, the new Model DR217 Series Radial Leaded Inductors from Datatronic Distribution, Inc., combine superior performance, reliability and long-life. The ROHS compliant DR217 Radial Leaded Inductors provide superior protection against challenging EMI/RFI problems in current handling applications up to 8.4 Amps. The proven, affordable DR217 Series offers extended life in temperatures ranging from -20 to +80°C.

C&K Components, a leading international supplier of tact switches, toggle, rocker and pushbutton switches, and smart card interconnect devices, has developed a Quad Navigation switch assembly. The four-way switch is available with backlit illumination and painted and laser etched buttons, and was designed specifically for GPS and communications applications, along with off-road vehicles, material handling equipment and instrumentation panels.

Murata's latest addition to its NFA18SL series of EMIFIL LC arrays, the NFA18SL227V1A45, has improved electrical performance with deeper insertion loss characteristics at high frequency, compared to the rest of the NFA18SL range. The new 3-terminal filter array is designed for blocking high frequency noise in parts of mobile phone handset, particularly the LCD and camera modules found in these applications.

The new MSM CS metal switch from SCHURTER is equipped with an actuator made of highly durable ceramic. Ceramic is a new technology employed in the production of an electro-mechanical switch. The new switch provides novel features that open up entirely new areas of application. The actuator material of the MSM CS is resistant to scratches, abrasion, impact and chemicals.

AVX offers designers the ability to clamp transients and filter EMI in one ultra compact device with the expansion of its Transguard multilayer varistor series. Designed for all small handheld devices, the miniature 0201 bi-directional transient voltage suppressor provides minimal signal distortion and low insertion loss.

DEM Manufacturing has uprated its MIF range of EMI filters in line with the Standard UL 1449 Third Edition, six months ahead of the standard coming into force, ensuring that these components offer superior surge and transient protection with immediate effect.

Providing design engineers with miniature devices designed for general encoding of low speed applications, TT electronics OPTEK Technology has developed a family of single- and dual-channel incremental encoders. Designated the OPE1275 single-channel (tachometer) and OPE2275 dual-channel encoders, the analog output encoders are designed for small shaft motors with a diameter of 2mm (0.079”) and a minimum length of 3.8mm (0.150”). The encoders ...
