FEATURES

100% Mumetal core for minimal THD and high inductance ensuring a high impedance over an excellent bandwidth together with low phase distortion. Mumetal can for magnetic shielding. Internal electroststic shield to ensure good common mode rejection and accurate phase splitting at high frequencies even with an unbalanced source. Available with threaded grommet (style e), PCB pins (style c) and side leads (style f). To see dimensions etc CLICK HERE
