There are two models
Let's introduce the first one: EI41X25mm specification Z9/Z11 iron core transformer.
parameter:
Primary copper resistance: 1280
Primary inductance: about 245H measured at 100HZ
Primary over DC: 15mA
Secondary copper resistance: 29+29
Secondary inductance: about 2H +2H 100HZ measured
Distributed capacitance: measured at 350P 20KHZ
Leakage inductance: 22mH 1KHZ measured
Frequency response: 5HZ-82KHZ -0.5DB, 105KHZ -1DB
Single measurement volume: 41X40X35mm
Weight: about 0.5KG/pair, the parameters are well matched.
Board size 100X63mm

TThe second type: EI41X25mm
parameter:
Primary copper resistance: 1280
Primary inductance: about 515H measured at 100HZ
Primary over DC: 15mA
Secondary copper resistance: 29+29
Secondary inductance: about 2.3H + 2.3H measured at 100HZ
Distributed capacitance: measured at 360P 20KHZ
Leakage inductance: 16mH 1KHZ measured
Frequency response: 5HZ-94KHZ -0.5DB, 115KHZ -1DB
Single measurement volume: 41X40X35mm
Weight: about 0.5KG/pair, the parameters are well matched.
Board size 100X63mm
Disclaimer: Transformer parameters are different due to different measuring instruments, different production batches, discrete parameters, etc., and are for reference only.
