Component library is free to design customers
TDK and Ansoft Corporation have announced the release of a new library for TDK's capacitor, inductor, common mode filter, and ferrite bead components for use in Ansoft Designer.
Wire-wound inductors go lead-free
The NLV32 and NLCV32 SMD are lead-free wire-wound inductors for signal lines.
The main unit of the SMD WiMAX circulator has been embedded in a hollowed-out resin substrate, which means that surface mounting and reflow solder can be used during PCB assembly.
In addition, the circulator casing is in direct contact with the mounting substrate, resulting in efficient heat dispersion and improved reliability.
The SMD format also allows flexible board layout and streamlined design compared to other WiMAX circulators.
TDK's SMD circulator is compatible with WiMAX (2.5 and 3.5 GHz) and wideband (200 MHz) frequencies.
A circulator is a three-terminal, high-frequency component that circulates signals entering each terminal to adjacent terminals.
These are key components for rectifying the transmission and reception of mobile communications in basestations.
WiMAX, or Worldwide Interoperability for Microwave Access, is a telecommunications technology based on the IEEE802.16 standard aimed at providing wireless data over long distances.
WiMAX allows for higher speed data communications compared to existing infrastructures.
TDK's WiMAX SMD circulator is available now, supplied either in volume tape-and-reel packaging or in sample books.
These parts are RoHS compliant, completely lead-free and have a specified operating temperature range between -55 and +85C.
