Vishay Intertechnology Inc. announced its technology lineup for the 2018 IEEE MTT International Microwave Symposium (IMS2018), being held June 10-15 at the Pennsylvania Convention Center in Philadelphia, Pa., in Booth #1412. At the conference and exhibition, the company will be highlighting its latest industry-leading high frequency multilayer ceramic chip capacitors (MLCC); specialty and RF thin and thick film resistors; wire bondable RF capacitors and inductors; and custom substrates.
Manufactured in noble metal electrode (NME) technology with a wet build process, Vishay Vitramon surface-mount high frequency MLCCs feature Q > 2000 and capacitance tolerance as tight as ± 0.05 pF, and they are available with lead (Pb)-free, lead (Pb)-bearing and non-magnetic copper terminations. In Booth #1412, QUAD high-power devices in the 0505, 1111, 2525 and 3838 case sizes will be on display for a wide range of high frequency applications, including MRI coils and generators, RF instrumentation and impedance matching networks. Highlighted leaded MLCCs will feature microstrip, axial ribbon and radial ribbon configurations.
In addition, Vishay Vitramon's high temperature surface-mount MLCCs in the 0402, 0505, 0603, 0805 and 1111 case sizes will be on display. The devices offer an operating temperature range from -55°C to +200°C and an ultra stable dielectric material with an excellent aging rate of zero percent per decade. The devices are designed to reduce signal loss and energy consumption in applications such as cellular base stations, satellite and broadband communication and wireless devices.
At IMS2018, Vishay Dale Thin Film will be highlighting a wide range of surface-mount precision thin film resistor chips, including devices with high frequency performance to 40 GHz; high-power ratings to 6 W; low TCR of 5 ppm/°C; high temperature operation to +250°C; enlarged backside terminations to reduce thermal resistance; and epoxy bondable devices with resistance from 1 Ω to 3 MΩ. Vishay Dale thick film chip resistors on display will include devices in the 0505, 0603, 1206 and 2512 case sizes with high-power ratings up to 22 W.
Highlighted Vishay Electro-Films (EFI) thin film components will include tantalum nitride microwave resistors in the 0201 and 0402 case sizes. Featuring alumina substrates, resistance from 2 Ω to 20 kΩ, and microwave resistance from 20 to 500 Ω, the devices are ideal for amplifiers, oscillators, attenuators, couplers and filters. In addition, wire bondable RF capacitors and spiral inductors offering low DCR and high Q will be exhibited.
Vishay EFI will also display custom substrates with sidewall patterning. Devices on display will include bare substrates and metallized plates in a variety of metal systems; conductor patterned substrates with wire bondable, solderable and epoxy-attach assembly options; resistor conductor patterned substrates; and Au-filled vias, wraps and cutout metal patterned substrates.
Part of International Microwave Week, IMS is the world's premier microwave conference. It features a large trade show, technical presentations, workshops and seminars covering a wide range of topics, including wireless communication, RF technologies, microwave electronics and applications and more.
