T: 1-425-776-1880 F: 1-425-776-2760 E: [email protected] www.pletronics.com Effective January 1, 2008 The SM11xxB series is discontinued. This has been discontinued because: • the difficulty of the older design to assemble well in the newer RoHS compliant high temperature reflow processes. • the cover assembly was not meeting some of the cleaning and assembly needs of the newer processes. • the components needed to make these parts are no longer available. This requirement is best met by using an SM77xxD 5x7mm SMD oscillator. Pl tronics,.
