Product Overview
Built with one primary winding and two secondary windings, the Aladdin 02-312 pulse transformer delivers a 1 : 51/64 : 2 turn ratio in a cylindrical metal enclosure with potted end faces. Designed for pulse shaping, signal coupling, and impedance matching in legacy electronics and timing circuitry, this component features three uninsulated wire leads exiting each end of the can.

- Nominal impedance: 3000 ohms primary, 2200 ohms secondary 1, 750 ohms secondary 2
- Pulse characteristics: 3.0 µs duration, 1.2 µs rise time, 20.0 kHz pulse repetition rate
- Peak secondary voltage rating: 20.0 V
- Package: Cylindrical metal can with potted faces, 0.688 in body length by 0.531 in diameter
- Terminations: 6 axial wire leads exiting both ends
- Government logistics cross-reference: NSN 5950-00-617-8695, CAGE 80483
Applications
- Restoring vintage communications, radar gear, avionics, and analog test instruments
- Triggering pulse generator circuits and SCR or thyristor gates requiring isolated drive signals
- Prototyping custom discrete timing, pulse-shaping, or specialized audio coupling circuits
Frequently Asked Questions
What is the winding layout on this transformer?
It contains one primary winding and two separate secondary windings, delivering nominal impedances of 3000 ohms, 2200 ohms, and 750 ohms across the respective stages.
What are the outer dimensions of the can?
The metal can measures 0.688 inches in body length and 0.531 inches in nominal outside diameter, excluding the wire leads extending from each end.
How are the lead connections identified on the body?
Terminal numbers 1 through 6 are printed directly around the metal cylinder wall adjacent to each lead exit point.
Built back when pulse shaping meant wound magnetic cores inside sealed metal cans. Hook up the leads, fire the pulse, and let the hardware do what it was born to do.
