I recently desoldered this transformer from a circuit board I found, and I need help identifying it. Do the numbers have anything to do with it?

1\$\begingroup\$ You might edit your question to say what the purpose of the circuit is, make / country of origin, pin spacing, etc. \$\endgroup\$– TransistorCommented Jul 22, 2022 at 10:41

2\$\begingroup\$ Something this small is unlikely to be for mains power, so my guess would be an audio transformer. Try putting an audio sine wave (e.g. 1 kHz) in one side, and see what comes out of the other side. That'll tell you the turns ratio, and if you find a similar-looking part, with similar turns ratio and resistance, you'll probably be in luck. \$\endgroup\$– jaybenCommented Jul 22, 2022 at 10:46

\$\begingroup\$ @jayben Audio transformer, or possibly an SMPS transformer. \$\endgroup\$– HearthCommented Jul 22, 2022 at 12:58

\$\begingroup\$ how many pins does it have? ... might not he a transformer \$\endgroup\$– jsotolaCommented Jul 22, 2022 at 15:51

\$\begingroup\$ Most probably custom. You can measure the core, measure or guesstimate the number of turns and perhaps use it for something useful. \$\endgroup\$– winnyCommented Jul 22, 2022 at 19:06

Often this is custom transformer and the code is an Internal Customer Code, related to his BOM. A saw similar transformers in old Servo Drive.
