Vishay Intertechnology has announced two thin film chip inductors in compact 0402 and 0603 case sizes that provide high Q values up to 49 at specified frequencies from 100 MHz to 1700 MHz. The Vishay Dale IFCB-0402 and IFCB-0603 are designed to provide stable inductance during high-frequency operation in communications devices such as cell phones, pagers, GPS devices, and wireless LANs, as well as for VCO, TCXO circuit, and RF transceiver modules. The IFCB-0402 provides inductance values ranging from 1.0 nH to 22 nH, while the IFCB-0603 is available in a range of values between 1.0 nH and 68 nH. Both inductors feature inductance tolerance of 0.3 nH from 1.0 nH to 8.2 nH, with 2% and 5% tolerances available. With dimensions of 1 x 0.5 mm and 1.6 x 0.8 mm and height profiles of 0.32 mm0.45 mm, respectively, the lightweight IFCB-0402 and IFCB-0603 allow for design of smaller end products for communications markets. They feature a lead (Pb)-free and RoHS-compliant construction and are compatible with reflow or flow soldering. Vishay Semiconductor GmbH , 74072 Heilbronn, Germany. www.vishay.com.
