Designing high-frequency pulse transformers requires meticulous attention to inner diameter tolerances and coil size. Engineers often encounter difficulties in controlling small inner diameter tolerances, raising questions about the possibility of enlarging tolerances.

While enlarging tolerances may seem like a feasible solution, it's essential to balance precision with practicality to maintain optimal transformer performance. Excessive tolerance enlargement can lead to compromised functionality and reliability in high-power high-frequency transformers.

Furthermore, irregularities in coil shape post-demolding pose additional challenges. Ensuring regularity in coil shape is vital for optimal performance and aesthetic appeal. Engineers employ strategic approaches to navigate these complexities and deliver high-performance transformers.
