Looking for 200V fixed inductor

Hi, sir/madame:
I am looking for 200V 10uH fixed inductor to build a 12V-to-200V buck converter using LT3757. A 10uH inductor sits in the path between 12V input and 200V output, so I need an inductor which tolerate 200V.

There is no search option of voltage rating for fixed inductor on the Digikey website. Is there any way to find them?

@Brad_Lin, welcome to Digi-Key TechForum.
Would you help to share your circuit design about your voltage conversion?

Refer to datasheet, below is 8V to 16V input to 24V output boost converter circuit. It uses 10uH inductor.

However, it suggests using high voltage flyback topology for your application (12V input to 200V output).
