75 Abracon UM-1  21.4 MHz Monolithic Crystal Filters, P/N ACF21W30A These were obtained as surplus a number of years ago, and never used. My understanding was they were new parts that never got sold. I have only been able to find one datasheet for it on DatasheetArchive.com, and it is included in the photos. The leads on this part are gold plated. One interesting thing is the datasheet shows the package as a UM-1, but the dimensions and appearance don't match. So it actually appears to be the HC-49 package. A newer datasheet from Abracon shows the UM-1.3 package also seems to match... I don't know which is correct. These will be mailed out via USPS Priority Mail in the US, and International First Class Mail for other countries. I normally mail on the same or next day after receiving the PayPal notification.
