SAW Devices (SAW Resonators and Filters in various Thru-hole and SMD packages)

Due to the large variety of frequencies and package styles, but also the complexity of the electrical parameters on SAW devices do we not post details on this page.

Please contact with your inquiry the NKG sales or marketing group or use general E-mail Sales@nkg.com.hk as first contact.

If you have detailed information on the wanted electrical parameters please forward same to us so that we can offer the best match possible.
