2 780 features Maxim Compatible Isolation to kv Surface Mount Options Toroidal Construction Standard Pinout UL 9V-0 Package Material Fully Encapsulated Low Profile Industrial Temperature Range description pin connections The 780 series of converter transformers are specifically designed for use with Maxim chipsets to provide isolated RS interfaces. Carefully controlled turns ratios ensure consistent performance whilst a toroidal construction minimises EMI. The surface mount devices are fully compatible with CECC0080 to 80 C which allows them to be placed and reflowed with IC s thus reducing time and cost in production. Pin DIP (top view) Primary Secondary Pin SM (top view)* Primary Secondary *Pin is connected to secondary centre tap. PRELIMINARY Notice : This is not a final specification. Some parametric limits may be subject to change. Newport Components 780
