New CJT series resistors from Tyco Electronics feature high IP ratings of IP33 up to IP54, making the devices superior to conventional ceramic resistors when used in harsh environments. Benefiting from easy airtight fitting and the ability to fit a heatsink, the resistors are ideal for inverter braking, as well as loading and charging circuits in harsh environmental conditions.

Microchip has announced the MCP9509 and MCP9510 (MCP9509/10) resistor-programmable, logic-output temperature switches. The MCP9509/10 temperature switches complement market trends toward smaller, lower power and less expensive end-products and represent a significant expansion of Microchip’s thermal-management product family.

The MAV Series from knitter-switch is designed to satisfy applications where resistance to vandals, water ingress and “difficult” environments is important. Typical applications include industrial shop floor systems, outdoor elevators and vending machines.

ON Semiconductor has unveiled the second device in a new line of temperature sensors recently acquired from Catalyst Semiconductor. The new CAT34TS02 combines a 12-bit (plus Sign bit) digital output temperature sensor with 2 kilobits (Kb) of Serial Presence Detect (SPD) EEPROM for DDR3 applications in high-speed PCs and laptops, graphics cards, servers, telecom equipment and base stations, environmental control systems and industrial process cont...

AVX Corporation has developed a new termination style for MnO2 (TLN Series) and polymer (TCN Series) tantalum capacitors that reduces the required internal construction space by up to 60 per cent and enables parts to be positioned very closely together.

Ecliptek Corporation has announced the expansion of its EMS MEMS spread spectrum low EMI output surface mount oscillator, the EMS4 series. The EMS4, in a miniature 2.0mm x 2.5mm package, reduces EMI at the clock source instead of locations later down the clock stream, potentially eliminating the use of supplemental shielding enclosures and/or filtering components.

Addressing the latest market demand, especially in the appliance industry, for higher electrical switching performance on little PCB space, Tyco Electronics has extended its well known and well established PB range of power relays with a new version called PB6.

Vishay Intertechnology has announced that its TR8 molded MicroTan tantalum chip capacitor was honored with an EDN China Innovation Award in the Passive Component, Connector, and Sensor category. Vishay received the award at a ceremony held on November 6 at the Jinjiang Shenzhen Airlines Hotel in Shenzhen, China. Accepting the award on behalf of Vishay was Tommy Cheng, Tantalum/MLCC Field Application Manager.

Carlo Gavazzi has introduced new heavy-duty infrared photo switches designed specifically for door and entrance applications. The IRPHS60 and IRPHS20 switches offer ranges of up to 60m indoors and up to 15 or 40m for outdoor installations.

ON Semiconductor has introduced the NUS6189, a device that integrates the performance and functions of an overvoltage protection (OVP) circuit, a 30 volt (V) P-channel power MOSFET, a low VCE(sat) transistor and a low Rds(on) power MOSFET into a space-saving 3.0 mm x 4.0 mm x 0.9 mm package. The NUS6189 is designed to protect sensitive electronic circuitry from overvoltage transients and power supply faults. It is optimized for applications that ...
