TDK unveils 1005-size band-pass filter
TDK Electronics
band-pass filter
TDK has developed the TFSB1, a 1005-size thin-film band-pass filter that is just 0.3mm thick.
The company applied the thin-film technologies that it developed through HDD magnetic head manufacturing, and formed thin films of copper wiring, insulation and dielectric material on a ceramic substrate to create an ultra-small band-pass filter - a 1005-size (1mm long by 0.5mm wide) component that is just 0.3mm thick.
The filter will be used primarily for ensuring signal quality in mobile phones, wireless LAN and Bluetooth modules, headsets, and other devices.
