Note :
1. HC-49/S has the same size of base and lead as of the HC-49/U Crystal Unit,
but with different height. There are two types of HC-49/S
Crystal Units as follows :


- Type 49/SS which is also called 49/3H with
height of 2.3 mm max


- Type 49/S3 which is also called 49/4H with
height of 3.6 mm max


2. Spesial Spesification other than above is on request.
