The MET-17 is a miniature encapsulated telecommunication coupling transformer designed to reflect a primary source impedance of 10 kΩ center-tapped to a 500 Ω center-tapped load on the secondary. It operates with a maximum level of 40 mW at 300 Hz and handles a maximum primary DC current of 1 mA. The device features a frequency response of ±2.0 dB from 300 Hz to 100 kHz and offers a dielectric strength of 500 Vrms between the primary and secondary windings. Its compact, encapsulated form factor is ideal for telecommunication coupling circuits requiring reliable performance in various operating conditions.
