SM capacitor gives top high-frequency performance
TTI is offering the ground breaking AO-CAP range of aluminium-polymer surface-mount capacitors from Kemet.
Coax connectors run up to 50GHz
Covering a frequency range from DC to 50GHz, embracing over 30 different series and comprising hundreds of versions, Amphenol's coaxial connectors are available from TTI.
Even with its smaller size, the previous sound pressure level (SPL) rating of Murata's larger SMD sounder can be maintained in the miniaturised package.
At 12 x 12 x 3mm the new sounder is an ideal replacement for more expensive electromechanical sounders that often have substantial current drain requirements.
Piezoelectric based sounders are used as low-current-drain audible devices for many applications where small size, SMD mounting and low current consumption is preferred or required.
Additionally, Murata's new sounder from TTI has several important features including gold flash electrodes for optional conductive glue mounting, reflow soldering and lead-free construction.
The sounder is also available in tape and reel packaging for automatic placement.
In many handheld applications, sounders are driven directly by a CMOS IC.
If the sounder is an electromechanical type, additional external components such as a transistor, diode, resistor and a capacitor may be required.
The Murata SMD piezoelectric sounder from TTI has an advantage over electromechanical sounders because it does not need additional external components when driven by a CMOS IC.
This offers designers additional opportunities for space saving and cost reduction, potentially in PDA or other handheld applications. Request a free brochure from TTI Europe ...
