How to select
A practical selection sequence
Narrow the published fields in sequence, compare the remaining candidates and verify the part-specific files before design-in.
- 01
Define the supply requirements
Record input range, output voltage, continuous load, startup needs, available space and thermal constraints.
- 02
Review the driver and windings
Identify the driver IC or circuit, operating frequency and drive arrangement, then check turns ratio, center taps and pins.
- 03
Compare electrical and mechanical requirements
Review isolation test conditions, inductance, DCR, leakage inductance and package. Confirm the required volt-time capability in the applicable document or with engineering.
- 04
Check the files and validate the candidate
Confirm document revisions and arrange sample testing. Request pricing directly for an identified part; have the FAE compare the original and candidate parts for a replacement project.
Key selection parameters
What each filter helps you decide
Inductance
Check measurement frequency, voltage and the stated minimum or tolerance. Similar values can have different test conditions.
DCR and leakage inductance
Compare the specified winding, conditions and maximum or typical value. These figures alone do not establish power, efficiency or temperature rise.
Isolation test conditions
Check AC/DC, test voltage, duration and pins together. A single test-voltage figure does not establish operating voltage or an insulation classification.
Volt-time capability
Review it against the voltage applied to the winding and its duration. Submit your drive conditions for confirmation where the part document does not provide this parameter.
Pins and package
Check polarity dots, center taps, dimensions and land pattern. A matching outline does not establish electrical compatibility.

Technical performance & application fit
Validate the complete design context
Application suitability is part-number specific. Treat the catalog fields as a shortlist, then confirm the design against the linked technical files.
RS485/CAN interface isolated power
- Specify the isolated-side voltage, transceiver and other loads, startup requirements and isolation boundary. This review concerns the power supply, not RS485/CAN data-signal transmission through the transformer.
Industrial control auxiliary power
- Share the control board's input range, output rails and loads, ambient conditions and available space to compare winding and thermal requirements.
Gate-driver power supplies
- Provide the driver part number, required supply rails and load, isolation requirements and drive arrangement for a part-specific FAE assessment.

Category overview
Push-pull transformers in isolated DC-DC stages
These parts belong inside an isolated converter, which is what separates them from a complete power module.

A component, not a module
A push-pull transformer provides the isolated magnetic coupling in a converter topology. It is not a finished DC-DC module: no switching controller, no rectification, no regulation. You supply those. If you need a drop-in isolated supply, buy a module; if you are designing the converter, this is the part.
Turns ratio sets the output
The ratio between primary and secondary windings, with the input voltage and the topology, determines the output voltage before regulation. Parts with multiple secondaries have a ratio for each. Read each winding's ratio from the datasheet rather than inferring it from the part number, because notation varies between series.
Inductance and frequency work together
Primary inductance, switching frequency and input voltage together determine how far the core is driven each cycle. Running a transformer below its intended frequency pushes the core toward saturation. Confirm the frequency range from the datasheet and verify flux margin at worst case.
FAQ & related guides
Questions before design-in
These answers guide the page workflow. Part-specific engineering limits still come from the linked technical files.
Does WHST06Q offer several parts to compare?
The current selector lists one part, WHST06Q02E0. This page supports checks of its winding arrangement, specifications and layout; it does not imply multiple interchangeable variants. For a different ratio or package, compare the main selector or submit your power requirements for sales and FAE review.
Does the 5 V input and 12 V output example define a fixed output?
No. The datasheet lists 5 V input, 12 V output, 460 mA and 400 kHz as typical application conditions and notes that results vary by application. This is not a regulated power-module guarantee. Provide the driver circuit, rectification and load for FAE review and sample validation.
How should I use the 1:2.88 turns ratio?
The full specification is 1CT:2.88CT ±3%, with center taps on both sides. Check pin assignments, winding polarity and the winding sections used in your circuit. Do not calculate the final output simply by multiplying the input by 2.88; drive, rectification and load conditions also require assessment.
Is sufficient board height enough to use WHST06Q?
No. The WHST06Q02E0 drawing specifies a maximum height of 4.10 mm and provides package dimensions, pin spacing and a suggested pad layout. Check board clearances, orientation and connections against that drawing. Available space alone does not establish footprint or electrical compatibility.
How can I assess WHST06Q as a replacement?
Provide the original manufacturer and full part number, datasheet revision, input/output conditions, frequency, load and PCB constraints. Add the requested sample quantity. Your sales engineer coordinates FAE matching and difference assessment. There is no automatic drop-in replacement decision; candidates require validation in the actual circuit.
