Bourns SM7505xPEL T1/E1 Transformer Models are potted construction versions of existing models SM75056EL and SM75057EL, which are produced using an injection molding method. The two new Bourns® models are low profile (5.65 mm) and feature a wide operating temperature range of -40 to +85 °C. Both devices are also RoHS compliant. Bourns designed the new T1/E1 models for telecom applications. With potted construction, Bourns' new T1/E1 transformer models provide an extra layer of protection in harsh operating environments, and in the assembly process. Potting also enables tighter board layouts by allowing parts to be placed much closer together," said Guido Zehnder, Product Line Manager at Bourns, Inc. "In addition, the shorter production lead times we are offering should help our customers achieve faster time-to-market for their telecom applications."
