Some information on TOKO RCL inductors and tuneable transformers
If you’ve ended up here, you are probably looking for information on some random TOKO RCL inductor you’ve found in your junk box. I got fed up of searching on part-numbers only to find people asking the same questions, trying to ID various parts, so I collected together the information I was able to find.
This is the information I’ve collected so far:
Measured values from random TOKO coils in my collection.
