Vishay Intertechnology Inc. added additional 650 V power MOSFETs to its E Series family of devices. These 22 new devices in eight different packages offer an extended on-resistance range from 30 to 600 milliohms at 10 V and broaden the series' maximum current ratings from 6 to 105 A. Based on the next generation of Vishay Siliconix Super Junction Technology, the 650 V E Series MOSFETs allow the company to offer extended headroom for applications that require additional input-voltage safety margin in its renewable, industrial, lighting, telecommunications, consumer, and computing markets. The devices introduced bring the total number of 650 V E Series MOSFETS to 26. All E Series devices offer ultra-low on-resistance and gate charge that translate into extremely low conduction and switching losses to save energy in high-power, high-performance switch mode applications, including power factor correction, server and telecom power systems, welding, uninterruptable power supplies (UPS), battery chargers, LED lighting, semiconductor capital equipment, adaptors, and solar inverters. The devices are designed to withstand high energy pulses in the avalanche and commutation mode with guaranteed limits through 100 % UIS testing. The MOSFETs are RoHS-compliant.

Vishay Intertechnology Inc. announced that it will be showcasing the company's latest industry-leading multi-layer ceramic chip capacitors (MLCCs) and surface-mount and wire-bondable thin film products at the 2013 IEEE MTT International Microwave Symposium (IMS), being held from June 2-7 at the Washington State Convention Center in Seattle. In booth 2303, Vishay Vitramon will introduce a new line of quad high-frequency, high-power MLCCs in 0505 and 1111 cases with high Q greater than 2000, ultra-low ESR, and voltage ratings from 25 VDC to 1500 VDC. The devices are optimized for a wide range of high-frequency applications, including MRI coils and generators, RF instrumentation, and impedance matching networks. In addition, Vishay Vitramon will highlight its surface-mount, high-frequency MLCCs in the 0402, 0603, and 0805 case sizes, which are ideal for commercial applications such as VoIP networks; cellular base stations; and satellite, WiFi (802.11), and WiMAX (802.16) wireless communication. At IMS 2013, Vishay Dale will be showcasing its high-frequency thin film chip resistors for low-noise amplifiers and line termination. Vishay Electro-Films (EFI) will be demonstrating surface-mount thin film RF capacitors for lumped element filters and impedance matching circuits, as well as wire-bondable thin film RF spiral inductors for RF tuning circuits and RF choking for DC biasing. In addition, Vishay EFI's RF filters and substrates will be on display. They offer a wide selection of materials and packaging capabilities and are qualified up to 70 GHz.

Vishay Intertechnology Inc. announced that it has extended its TANTAMOUNT(R) 597D series of commercial solid tantalum chip capacitors with a new Hi-Rel version approved to Defense Logistics Agency (DLA) Specification 13008. Built with Vishay's proprietary high-voltage dielectric formation process, the Vishay Sprague 13008 series is ideal for +28 V power supply designs in military and aerospace applications. The capacitors released on May 20, 2013 are optimized for DC/DC conversion and power distribution in weapons and radar systems, avionics, and space-based electronics. To ensure performance in these safety-critical applications, the devices offer high-reliability screening and surge current testing options in accordance with MIL-PRF-55365. Available in nine case sizes, 13008 series capacitors provide a wide array of ratings not previously found in available MIL specifications, including a capacitance range of 10 to 1500 microfarads over a voltage range from 4 V to 63 V. The devices' 63 V rating allows designers to meet derating requirements of 50 % rated voltage for use in MIL-STD-1275 +28 V power supply designs. Their dual anode construction ensures the lowest ESR in their class, down to 0.015 ohms at +25 degC and 100 kHz. The 13008 series operates over a temperature range of -55 degC to +85 degC, to +125 degC with voltage derating. With their conformal coating, the capacitors offer better volumetric efficiency than molded devices. This allows for higher capacitance-voltage (CV), a figure of merit that measures the amount of energy a capacitor can store.
