ee www.DataSheet4U.com Document 193 -1 Miniature SMT Transformers Designed specifically for use with Maxim RS-232/RS-485 interface ICs, these miniature transformers are also suitable for gate drive and other power applications. They were designed to work with the MAX253 and MAX845 for providing power to the isolated side of the interface. They feature 1500 Vrms isolation between windings in a miniature surface mount package. All transformers have a plastic cover to aid automated placement. In addition to the standard parts shown, Coilcraft can produce custom transformers with voltage, inductance and DCR values to meet your specific requirements.
