The electrical parameters do not change. The switch from the common 2pad to the new 3pad package can be handled without extensive tests.
A frequency tolerance of +-5ppm at 25°C and a frequency stability from +-5ppm (0°C to +50°C) are possible.
In the normal production process we achieve temperature stabilities of between +-100ppm and +-150ppm over a temperature range of -40°C to +125°C.
The layout of the SMD crystal HC-49/US-SMD is the same as that of the competition. This compatibility makes the HC-49/US-SMD a direct drop in replacement.
The SMD crystal HC-49/US-SMD can be used for all applications where a miniaturised low cost and high performance crystal clock generator is required.
The crystals in the HC-49/US-SMD series of PETERMANN-TECHNIK are manufactured exclusively in clean rooms and only crystal blanks are used that come from our own production. In this way the HC-49/US-SMD series offers its users the absolute best possible quality. If needed, this crystal can also be qualified to the automotive norm,
AEC-Q200REV-C.
The extensive depth of manufacturing processes enables PETERMANN-TECHNIK to achieve excellent yields. In this way we can offer low prices together with exceptional quality. This is of course also true for customer specials.
The HC-49/US-SMD crystals are lead (Pb) free and are RoHS (Restriction of the use of certain hazardous substances in electrical and electronic equipment) conform according to the EU directive 2002/95/EG. The products of PETERMANN-TECHNIK can be soldered according to JEDEC Norm J-STD-020C (Reflow), JESD22-B106-C (Wave) and the
