Hello All, I am trying to source 121.5 Mhz SMD oscillators but not having any luck so far. Looked on all the major supplier sites but they are either 120Mhz or then 122Mhz. Can someone please help?
Thanks!

What are you using 121.5MHz for?
That is "Guard Band" for aviation. Emergency Locator Transmitters will use
that frequency in the case of a crash (along with 406MHz).
Hi Ali,
Are you sure about that? It looks like a date code.
Hi Ali,
I think shabaz got a point. That may be like a date code. I googled SMD oscillators images and seems most of them print the rated frequency with a high precision (many zeroes, indicating KHz, MHz, and so on), so I wouldn't count on this one being 121.5 Mhz as there is no decimal point or MHz in the marks anywhere. I'd say the number at the top may give you a better indication but can't read it properly.
