ZXY-EI25 Flying Lead Audio Isolation Transformer, 1:4 Turns Ratio, 50 Hz-20 kHz, EI25 Laminated Core
ZXY-EI25, a flying-lead audio isolation transformer built on an EI25 laminated core. Its two windings are isolated and wound to a 1:4 turns ratio. At 1 kHz and 0.3 V the primary measures 56 mH min and the secondary 800 mH min; DC resistance at 25 °C is 1.6 Ω on the primary and 17 Ω on the secondary, ±15 %. The part covers 50 Hz to 20 kHz and is designed for low distortion across that band, which is why it is described as both a voice and a data coupling transformer.

ZXY EI28-600:600 Audio Isolation Transformer - Permalloy Core 600 Ohm to 600 Ohm 1:1 Turns Ratio Audio Isolation Transformer for PCB Mounting
The ZXY EI28-600:600 is a 1:1 audio isolation transformer built on a high-permeability permalloy laminated core. It couples a balanced signal from primary to secondary at matched 600 Ω impedance and transfers audio from 20 Hz to 20 kHz without changing signal level, while galvanically separating the two windings so that ground loops, DC offset and common-mode noise never reach the downstream stage.
