ElectronicsThe K10101A part with Optocouplers DIP-4 RoHS by Cosmo Electronics is a 4-pin optocoupler module embedded with a light emitting diode (LED) and a detector voltage transformer (DVT). It is a double-insulated component with a transfer buffer that separates the input and output circuits, making it ideal for electric isolation. It is RoHS compliant, meaning it contains no hazardous substances such as lead, cadmium, and mercury, making it environmentally compliant. It also features a wide input range of 3.75 V DC to 30 V DC, low power consumption, low input to output isolation leakage, and a high rate of insertion loss. This part is used in industrial and consumer markets to provide reliable electrical isolation as a signal isolator or for data communications.
