RM6 / RM10 etc. I wondered: "Why is it called a pot core - it doesn't look much like a pot ?" Anyone know how the pot-core got it's name ? Silly, I know, but one does like to know these things ... I always understood this was short for "potted", and presumably refers to the complete encapsulation of the inductance in ferrite that occurs in most 'pot cores'. It may also be connected with the ceramic (ie pottery) mixed with iron dust to make the ferrite. Mike, G3XDV ========== |
