"Custom transformer" is too broad for an engineering quotation. A mains-frequency PCB transformer, an SMPS transformer and a planar transformer sit in different circuits and are designed around different electrical, thermal and mechanical constraints.
TrafoPSU organises its magnetic-component range into PCB transformers, SMPS transformers and planar transformers, alongside inductors, chokes and related custom magnetics. The category should be selected from the circuit first, not from the physical appearance of an existing sample.
For a transformer enquiry, engineers should provide the circuit topology and switching frequency where applicable, input and output conditions, power level, isolation requirement, duty cycle, target dimensions and mounting method. Temperature rise and available airflow need to be considered with the enclosure. For an inductor or choke, current, inductance and ripple conditions are central to the discussion.
When replacing an existing magnetic component, sending a sample can help with mechanical comparison, but the electrical specification remains essential. Reverse-engineering a part without knowing its circuit conditions can reproduce dimensions while missing the reason behind the original design.
Electronics teams can review TrafoPSU's planar transformer range and the PCB and SMPS transformer categories before preparing a complete design requirement.
