140EX Impedance Matching Audio Transformers

Hammond's 140EX Studio-Grade Impedance Matching Audio Transformers operate in the 20Hz to 20KHz frequency range. The metal can construction provides excellent shielding from a broad range of external sources. They are designed for maximum bandwidth and low distortion (at +10dBm power level or less). The nickel core provides high permeability combined with low losses. Typical applications for these audio transformers include input/output isolation, line matching, driver, and hybrid applications.
