com 78250 Series MAX250/MAX251 Compatible Converter Transformers FEATURES „RoHS compliant „Maxim MAX250/MAX251 compatible „Isolation to 4kVrms „Industry-standard pinout „Surface mount option „UL 94 V-0 package materials „Low profile „Toroidal construction „Fully encapsulated „Industrial temperature range DESCRIPTION The 78250 series of converter transformers are specifically designed for use with Maxim chipsets to provide isolated RS232 interfaces.
Carefully controlled turns ratios ensure consistent performance whilst a toroidal construction minimises EMI.
Surface-mount parts The surface-mount (M suffix) products are not recommended for new designs.
For existing designs, however, Murata Power Solutions will continue to manufacture and fully support these parts.
For recommended alternatives please refer to the 78250J Series datasheet.
