Siemens , Philips and other manufactures talk then only about RM- core not pot-cores. 73 Matti/OH2ZT ----- Original Message ----- From: "Hugh M0WYE" To: Sent: Monday, September 22, 2003 6:30 PM Subject: LF: Pot cores > Hi Group > While pondering a filter design and playing with a pot core type inductor... > 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 ... > 73 > Hugh M0WYE > > >
