ZXYDU19 is a permalloy audio isolation transformer in a sealed metal case with DIP through-hole pins. Turns ratio 1:1+1+1: one primary and three independent secondaries on a single high-permeability nickel-iron core. Frequency range 10 Hz to 100 kHz at ±0.5 dB; maximum 50 Hz input +6 dBu at 0.2% THD; primary DCR 32 Ω MAX and secondary DCR 63 + 67 + 72 Ω MAX at 25 °C; dielectric strength 1250 V at 1 mA for 60 s. The galvanic barrier blocks DC and ground potential differences between circuits and removes the AC hum caused by ground loops, while attenuating external interference in both balanced and unbalanced lines. Case 47.5 x 29.0 x 24.0 mm with 2.5 / 30.7 / 2.5 mm pin rows for direct PCB mounting.
EI66*28 encapsulated audio isolation transformer for audio amplifier and low-frequency isolation duty. Wound for a 220 V AC, 50 Hz primary with a 23 V ±5% no-load output on the blue-blue winding, 55 mA MAX no-load current and 4.5 W MAX no-load loss. H50N electrical steel EI66 laminated core, flame-retardant Nylon 101 bobbin, vacuum varnish impregnated and fully encapsulated, zinc-plated steel mounting bracket, 250 ±10 mm silicone lead wires with tinned copper terminations. AC 1500 V primary-secondary and AC 1000 V winding-to-core dielectric strength, insulation resistance ≥100 MΩ MIN. ZXY Part No. B2348, specification 20230803003.
The EI-4120W-5409 is a chassis-mount power transformer with a dual 110 V primary that can be wired for either 110 V or 220 V mains, and a centre-tapped secondary giving 12 V-0-12 V or 24 V at 250 mA. It is built on an EI-41 silicon steel lamination in a flame-retardant bobbin, sealed in a metal cover with two mounting flanges, and terminated in eight 6.3 x 0.8 mm solder tabs arranged 4 + 4.
The EE25-4.0H is a PCB-mountable audio isolation transformer built on the EE25 in-line bobbin platform. A 1:1:1:1 turns ratio and four matched 4.0 H windings give the part galvanic isolation between circuits, rejection of the AC hum created by system grounding, and clean coupling of balanced or unbalanced audio signals across the 20 Hz to 20 kHz range. It is used for voice and data coupling, for breaking ground loops between pieces of equipment, and for providing an isolated signal output.
The ZXY-3108 is a 12:1 audio isolation transformer built on a permalloy core and sealed in a mu-metal case. It combines a 140 kOhm primary impedance with a 12:1 (N1:N2) turns ratio to provide galvanic isolation and effective common-mode noise rejection in high-impedance, high-fidelity audio signal paths. The unit is supplied as a 31.0 mm x 22.0 mm vertical-mount body with a 4 + 4 pin arrangement for through-hole PCB layouts.
The ZXY-ED8X10-2.0H is a small glue-sealed SMD audio isolation transformer built on an ED8 x 10 laminated core. Two matched windings give 1:1 galvanic isolation between a 600 ohm line port and a 400 ohm device port, with a flat response across the 300 Hz to 4 kHz band, for board-level use in audio, voice and communication equipment.
The ZXY-EE25 is a compact audio isolation transformer built on a high-grade EE25 silicon-steel core and terminated with multi-color flying leads. With a 1:4 turns ratio, an inductance range of 65 mH to 900 mH at 1 kHz and pre-stripped, tinned copper lead tips, it provides impedance matching, galvanic signal isolation and ground-loop noise rejection in professional audio, broadcast, communication and industrial audio equipment.
ZXYAUDIO EE24 is a low frequency audio transformer for signal coupling and isolation in audio equipment.
