Bourns has advised that effective October 1, 2011, the conformal coating color of the Models 77F and 78F will change from blue to green. The characteristics and properties of the conformal coating epoxy material remain the same. The change of color does not affect form, fit or function. During the changeover while shipments may contain both blue and green colored parts, they will not be mixed within individual reels. Please contact a Mouser Technical Sales Representative for further information. 5-1011-1
