TACT switches slim to compact applications
Alps Electric has released the industry's thinnest double-action TACT switches for applications such as shutter buttons for digital still and video cameras.
Conforming with the European CE Standard and FCC Standards, the tuner modules can be used for car CD players and car radio units.
The TFTC7 series is rated for voltages of 7.5 to 8.5V and has a typical current consumption of 95mA.
Providing a distortion of typical 0.3% (FM) or rather 0.5% (AM), an image rejection ratio of typical 55 or 75dB (AM), an IF rejection ratio of typical 80dB or rather 60dB (AM)/50dB (LW), they operate within a temperature range from -30 to +80C.
The limiting FM sensitivity is -1dBu and the maximum AM sensitivity is 20dBu.
The antenna input impedance amounts to 75ohm.
Alps adopted its high-density mounting technology to ensure a compact, low-profile design that enables effective use of setting space.
Another advantage of the TFTC7 series is that the FM and AM section respectively incorporate a circuitry up to the audio-output stage, which eliminates RF adjustments during the performance review and set installation, thus enabling a reduction in man-hours in productions.
