’s 1812-W2E-2555S is a surface-mount, 2W, thru-hole, wide-band, transformer. It is designed to electrically transform an input signal voltage into a higher output voltage, while maintaining electrical isolation between the input and output of the circuit. The device has a frequency range of 50 to 500K Hertz, and its power rating is 2W. It has an operating temperature range of -25°C to 125°C. The transformer is enclosed in a 4-by-1.5 by-1 inch plastic package with a 25-pin connector. It has a low insertion loss and a high common-mode rejection ratio. Its standard winding configuration is center-tapped primary, dual secondary. The 1812-W2E-2555S is designed for use in applications where high-fidelity signal transmission, isolation and transformation is required. It can be used in a variety of audio and video equipment, as well as in telecommunications and data transmission equipment.
