UM1 CRYSTALS
ISSUE 8; 15 JUNE 1998
Delivery Options
Common frequencies are available from stock. Please
see p4 for details
3 day Express Manufacturing Service, subject to piece
part stock availability
Holder Style
UM1 crystals are resistance welded, hermetically
sealed in an inert atmosphere with glass to metal seals
securing the lead wires
Holders suffixed ‘–3L have a centre third wire which
grounds the case
HC45 is not dimensionally identical to the UM1 but
for most purposes the two are interchangeable
