Designing high-frequency pulse transformers involves meticulous attention to detail, particularly concerning inner diameter tolerances and coil size. Engineers often encounter challenges with small inner diameter tolerances, making them difficult to control. A common query arises: can these tolerances be enlarged?

While enlarging tolerances may seem like a viable solution, it's crucial to maintain precision within permissible limits to ensure optimal performance. Enlarging tolerances excessively can lead to compromised functionality and reliability in high-frequency pulse transformers.

Another pertinent issue engineers face is the irregularity of coil shape post-demolding. Large circular coils may deviate from regularity, impacting performance and aesthetics. Striking a balance between tolerance control and coil regularity is imperative in high-power high-frequency transformer design.
