Using high frequency ferrite like N27 for 1 Khz

[manishanand14]

Can I use N 27 material for low frequency like 400-1Khz.

I am using a pot core inductor of N 27 material for LC filter

Can you imagine a reason why it shouldn't be possible? Apart from this general point, N27 isn't particularly "high frequency" ferrite, rather dedicated for power transformers, predecissor of N87 etc.
