- Inverter input filter window trials
- Busbar EMI choke prototyping
- Comparing 144.5 mm, 165.5 mm, and 250 mm racetrack windows
How to use
Start with the 144.5 mm or 165.5 mm window when the bundle fits. Move to the 250 mm PBT-cased core when the busbar or cable bundle needs the longer slot. Confirm the finish on each linked SKU before you lock a production part.
FAQ
Why do the finishes differ inside this kit?
The 144.5 mm and 165.5 mm cores are crepe tape and electrical tape. The 250 mm core is black PBT Class B. Compare the window first, then confirm the finish on the linked SKU.
What happens after I pick a winning size?
Reorder that single catalog SKU in pack quantities (or request a production-gapped cut core). Kits are for size and gap exploration, not a substitute for locking a production part number.
Do kits ship with datasheets?
Each included SKU has its own product page with dimensions, AL, and photos. Open the linked part numbers in the contents table for datasheets and specs.
