The series 114 Centigrid® relay is an ultraminiature, hermetically sealed, armature relay. Its low profile height (0.275"") and 0.100"" grid spaced terminals, which precludes the need for spreader pads, make it ideal for applications where extreme packaging density and/or close PC board spacing are required. The basic design and internal construction are similar to the standard Teledyne DPDT TO-5 relay (e.g., Series 412). By virtue of its inherently low intercontact capacitance and contact circuit losses, the 114 relay has proven to be an excellent ultraminiature RF switch for frequency ranges well into the UHF spectrum. A typical RF application for the 114 relay is in handheld radio transceivers, wherein the combined features of good RF performance, small size, low coil power dissipation and high reliability make it a preferred method of Transmit-Receive switching.
