The CYPS2701-1(L-TP) with Optocouplers SOP-4 RoHS is a 4-pin, surface mount optocoupler. It features 4 channels of isolation, which are designed to provide electrical and optical isolation between two circuits, making them useful for applications requiring protection against electromagnetic interference (EMI). This optocoupler is manufactured by OCIC, a leading global manufacturer of optoelectronic components, and is RoHS compliant. The CYPS2701-1 features high insulation voltage and excellent common mode transient immunity. It also has low saturation voltage and high CTR ratio for high noise immunity. For low power consumption, the CYPS2701-1 is a great choice and can be used in a variety of applications.
