Milspec Parts Dated in the 70’s
Package TO3
Silicon NPN Similar to 2N1490
Included with the transistor is a TO3 shaped Mica insulating washer and 2 Nylon spacers.
NSN (National Stock Number) 5961 99 037 4912
10CV 374912
CV9868
A NATO Stock Number, or National Stock Number (NSN) as it is known in the US, is a 13-digit numeric code, identifying all the ‘standardized material items of supply’ as they have been recognized by all NATO countries including United States Department of Defense.
Dating from the 70’s these transistors were made during the transition from glass valves, interestingly they are labelled ‘valve electronic’ and packed in the old valve style 3.5″ x 1.25″ x 1.25″ boxes.

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for some time (date coded in the 70’s), we have therefore classified them as ‘new other’, they are however pristine, stored with us sealed in original packaging and in good serviceable condition, the photographs are representative of their general appearance, being of some of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
