78250J Series
MAX250/MAX251 Compatible Converter SM Transformers
FEATURES J-STD-020D reflow 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 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. For through hole versions see 78250 datasheet.
