Source: Vishay IntertechnologySource: Vishay IntertechnologyAt its booth at the International Microwave Symposium (IMS2018), running June 10-15, 2018, in Philadelphia, one of the largest manufacturers of discrete semiconductors and passive electronic components is showcasing some of its industry-leading products.

The company, Vishay Intertechnology, makes components used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies and medical markets.

Products on display at IMS include Vishay's latest high-frequency multilayer ceramic chip capacitors (MLCCs); specialty and RF thin and thick film resistors; wire bondable RF capacitors and inductors; and custom substrates.

Vishay Vitramon MLCCs

Manufactured with 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. QUAD high power devices in 0505, 1111, 2525 and 3838 case sizes have a wide range of high-frequency applications, including MRI coils and generators, RF instrumentation and impedance matching networks. Leaded MLCCs are available in microstrip, axial ribbon and radial ribbon configurations.

In addition, Vishay Vitramon’s high-temperature surface-mount MLCCs in 0402, 0505, 0603, 0805 and 1111 case sizes 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.

Thin/Thick Film Resistors

Vishay Dale surface-mount precision thin film resistor chips offer 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 W to 3 MW. Vishay Dale thick film chip resistors are available in 0505, 0603, 1206 and 2512 case sizes with high power ratings up to 22 W.

In addition, Vishay Electro-Films (EFI) thin film are used as components for tantalum nitride microwave resistors in 0201 and 0402 case sizes. Featuring alumina substrates, resistance from 2 Ω to 20 kΩ and microwave resistance from 20 Ω to 500 Ω, the devices are ideal for amplifiers, oscillators, attenuators, couplers and filters. Also available are wire bondable RF capacitors and spiral inductors offering low DCR and high Q will be exhibited.

Custom Substrates

Vishay EFI also offers custom substrates with sidewall patterning. Options 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.
