Aladdin 02-312 Pulse Transformer - Hermetically Sealed, 6-Lead
Condition
This Aladdin 02-312 pulse transformer is New. The photographed unit is a bright metal cylindrical case with the Aladdin name and 02-312 part number printed on the body, along with pin numbers 1 through 6 identifying each lead; the ends of the can are bare potted faces with no marking. The six wire leads are wavy and kinked from handling, crossing one another where they leave the can, and the wire reads dull grey rather than bright in photos 3 and 4. Same or next business day shipping from our Idaho warehouse. Honest pricing, no nonsense.

Product Overview
The Aladdin 02-312 is a hermetically sealed pulse transformer built around one primary winding and two secondary windings, for a primary-to-secondary turn ratio of 1 to 51/64 to 2. Nominal impedance is rated at 3000 ohms on the primary, 2200 ohms on the first secondary, and 750 ohms on the second secondary. The unit carries a 3.0 microsecond pulse duration and a 1.2 microsecond pulse rise time (non-core) at a 20.0 kilohertz pulse repetition rate, with a peak voltage rating of 20.0 volts across the secondaries (non-core). Six wire leads, numbered 1 through 6 on the case, exit the can for terminal-style mounting. The metal case measures 0.688 inches nominal body length by 0.531 inches nominal outside diameter.

Applications
- Technicians repairing legacy pulse or trigger circuits in radar, telemetry, or timing gear that call for this exact turn ratio and impedance
- Engineers prototyping pulse-coupling or pulse-shaping networks who need a hermetically sealed transformer without winding a custom part
- Bench techs replacing an obsolete 02-312 in older test equipment where an exact spec match matters
- Restorers of vintage electronics needing a compact, known-spec pulse or isolation transformer
Frequently Asked Questions
What are the electrical specs of the Aladdin 02-312?
It carries a 1 to 51/64 to 2 primary-to-secondary turn ratio, nominal impedance of 3000 ohms primary, 2200 ohms on the first secondary, and 750 ohms on the second secondary, a 3.0 microsecond pulse duration, a 1.2 microsecond rise time, and a 20.0 kilohertz pulse repetition rate, with a 20.0 volt peak rating across the secondaries.
Which lead is which winding?
The case is printed with pin numbers 1 through 6, but our inventory data does not include a pin-to-winding schematic. Not confirmed - verify pin assignments against the datasheet or with a meter before use.
What size is this transformer and how does it mount?
The metal can measures 0.688 inches nominal in body length by 0.531 inches nominal in outside diameter. It mounts by its six wire leads in a terminal-style connection rather than a PCB footprint.
Why buy this one instead of a surplus lot?
This is a single photographed piece with a confirmed turn ratio, impedance, and pulse rating already in hand, not an unmarked assortment from a pull bag. Shipping is $8 flat rate, free once your order passes $28, and it leaves our Idaho warehouse the same or next business day.
Hermetically sealed and printed with the pin numbers that mattered to whoever built the circuit it was destined for, this Aladdin 02-312 was made for gear where a pulse either shows up on time or it does not. If your build needs that exact turn ratio and impedance, it is ready for the next chassis.
