It is the new series of small size ceramic resonators, manufactured by Advanced Crystal Technology, which offer an economic alternative to superficial assembly crystals in all those projects where a particularly stringent tolerance is not required.

These new resonators include four families of products: two terminals ACT ZTAC and ACT 22MB; three terminals ACT ZTTC and ACT ZTMD, the latter of which includes also the condensers.

The range of frequencies goes from 1,79 and 50,00 MHz and can work with temperatures included between -20°C and +80°C.

With an overall size between 7,4x3,4x1,8 mm, and 3,7x3,1x1,2 mm, these resonators are suited for being placed in the card with other superficial assembly components, thus eliminating costs for manual welding.

All models offer aging characteristics, over a period of 10 years, of just 0,3 %.
