New Components, Modules, and Subassemblies: January 2009
December 31, 1969 |Estimated reading time: 6 minutes
Following are the new products, reports, and software tools in the component sector, including power splitters, capacitors, sensors, connectors, varistors, oscillators, and more. Products come from AVX, IMS, Molex, Fox Electronics, EPCOS, and other companies in the component manufacturing industry.
International Manufacturing Services Inc. (IMS) debuted a series of 1-W two-way resistive power splitters, available with 50 or 75 Ω impedances. The 75-⁞ IPS series two-way splitters feature wraparound or single- sided terminals and target broadcast applications. These resistive power splitters have 6 dB evenly split attenuation and operate from DC to 20 GHz. Attenuation accuracy is ±0.5 dB; VSWR equals 1.3:1. www.ims-resistors.com.
AVX Corporation launched the latest version of its SpiTanII software that enables designers to view all basic characteristics and parameters for tantalum and Oxicap (niobium oxide) capacitors. The company also expanded the PSpice simulation software libraries for its tantalum, tantalum polymer, and niobium oxide chip parts, and introduced V6.0 of its Select-a-Cap software tool. The software tools are designed to improve the PC-based design-in process for tantalum and niobium oxide capacitors. SpiTanII enables the designer to choose a desired component by part number or by reference to capacitance, rated voltage, case size, or series. For the selected capacitor, all basic parameters, such as frequency characteristics of capacitance, ESR, impedance, DF and ripple current and ripple voltage ratings, are displayed. Version 1.7 includes new parts from TAJ, Oxicap, NOJ, and TLJ Series, as well as from high-temperature THJ Series and low-ESR TPS Series ranges. The software can be downloaded from AVX website at www.avx.com. AVX has also expanded its PSpice simulation software libraries, adding about 500 new models to match the product range covered by SpitanII V1.7. Libraries include all electrical parameters, enabling fast simulation of practical circuit designs. AVX's tantalum and NbO capacitor libraries provide both frequency and transient simulations over the full operating temperature ranges for each device.

MurataMurata Electronics North America introduced the Thermo-String temperature sensor. The thermistor is fitted with long wire leads (up to 150 mm) to allow placement close to hot spot areas that may not be on the PCB or reachable by surface mount negative temperature coefficient (NTC) thermistors on the motherboard. Utilizing Murata's current NCP series surface mount NTC thermistor line to provide accurate temperature measurement over wide temperature ranges, the Thermo-String NXF series has a leaded package to reduce design-in costs. With a maximum head size of 2 mm, the sensor provides operating temperatures in the range of -40° to +125°C for commercial grade. Suitable for lead-free soldering, the thermistor is resistant to mechanical vibrations and shock and meets ELV/UL requirements. www.murata-northamerica.com.
Fox ElectronicsFox Electronics expanded its XpressO oscillator series to include a 2.5-volt LVPECL VCXO version with an industry-standard 7 × 5 mm package and a frequency range from 0.75 MHz through 1.0 GHz. The series uses proprietary application-specific integrated circuits (ASICs) with a focus on noise reduction technologies and lower jitter. The FVXO-PC72 oscillators employ a third order delta sigma modulator (DSM) to reduce noise to levels comparable to traditional bulk quartz and SAW oscillators. The LVPECL VCXO versions offer shorter lead times. The LVPECL VCXOs offer a frequency resolution to six decimal places, an absolute pull range (APR) of +50 ppm and operating temperatures of -20° to +70°C or -40° to +85°C. RoHS compliant, they have a tri-state enable/disable feature; and are constructed with a gold over nickel termination finish. Serial identification enables comprehensive traceability. www.foxonline.com.
EPCOS developed a rugged series of multiple-pulse MP varistors for applications in which repetitive surges can be expected, such as in switch-mode power supplies, drives, or general overvoltage protection modules. The varistors are offered with diameters of 10, 14, and 20 mm. They can withstand surge currents of 1.5 to 5 kA with 15 pulses of 8/20 µs at intervals of 60 seconds. Their rated voltages cover the range from 275 to 460 V AC. EPCOS is currently developing types that will extend the protection for line voltages from 130 to 680 V AC. www.epcos.com.
AVX Corporation developed a high-capacitance PulseCap capacitor in a low-profile package. The capacitors are designed for applications such as PCMCIA/USB wireless express cards where bulk capacitance is needed to boost transmitter power. These large-case-size tantalum products are rated at 2200 µF/6.3V. A maximum case height of 2 mm suits reduced-height applications. The undertab termination style increases volumetric efficiency and allows parts to be positioned closely together. PulseCap devices are RoHS compatible and capable of withstanding a soldering profile of 3× reflow at 260°C. Operating temperature range is -55° to +125°C. Other applications include wireless data cards, metering and sensors. www.avx.com.
EPCOS also introduced E-series multilayer ceramic capacitors based on the X7R material, designed to be more resistant to ESD pulses than standard types. The E-series offers low capacitance values of down to 1 nF, protecting against EMI up to 300 MHz. The capacitors are offered in sizes 0603 and 0805 with capacitances from 1 to 10 nF and voltages of between 50 and 100 V. Typical ESD levels are 18, 9, and 25 kV to AEC-Q200. They are compatible with existing designs based on standard multilayer capacitors. www.epcos.com.
Epson Toyocom Corporation's U.S.-based Timing Products Division released small real-time clock modules. The maximum dimensions of the RTC modules, RX-4571BD and RX-8571BD, are 3.4 × 1.7 × 1.0t mm. The modules suit time and date data management applications. The RX-4571BD supports a 3-wire serial interface, while the RX-8571BD is I2C-Bus interface compliant. The RX-4571BD and RX-8571BD, equipped with an ultra-compact QMEMS crystal chip, are built using new platform oscillator (NPO) structure, wherein a crystal unit in a ceramic package is sealed together with an oscillation circuit in a molded plastic housing. In Standby, the RX-4571BD consumes 0.32 µA of current, the RX-8571BD consumes 0.22 µA (at 3 V, respectively). www.eea.epson.com.
