Vishay Intertechnology Inc. has rolled out four new members of the company's Vitramon family of surface-mount multilayer ceramic (MLCC) chip antennas.

The VJ5301M868MXBSR measures 35 x 5 x1.2mm and is designed for the reception and transmission of digital signals at frequencies of 868MHz at 868MHz.

The VJ5601M868MXBSR also operates at 868MHz but measures 15.5 x 10.5mm x 1.2mm.

The VJ5301M915MXBSR and VJ5601M915MXBSR operate at 915MHz and measure 35 x 5 x 1.2mm and 15.5 x 10.5 x 1.2mm, respectively.

The chip antennas comply with the MBRAI standard for portable communication and feature 50 unbalanced tuning interfaces and operating temperature ranges from -40C to +85C.

They are suited medical telemetry and instrumentation, industrial automation, security and home automation systems, gas and water meters, remote sensing and control, and long-range RFID. In these applications, the devices help to lower costs by eliminating the need for large external wipe antennas.

Manufactured in noble metal electrode technology (NME) with a wet build process, the four antennas offer a high-reliability, ceramic-oxide body construction. The RoHS-compliant chip antennas are halogen-free per IEC 61249-2-21 and designed to be assembled onto a PC board using a standard reflow process.

Samples and production quantities of the new chip antennas are available now, with a lead time of nine weeks for larger orders.
