1354233 Inductors TELEFONAKTIEBOLAGET L M ERICSSON 24 March 1972 [7 April 1971] 13986/72 Heading HIT A choke for use in filtering radio frequency noise comprises a magnetic core 12 having a number of winding layers 13, 14, 15 connected in parallel to the terminals 17, 18 of the choke so that in use neighbouring turns in adjacent layers are on the same potential. The core construction avoids all but a very small air gap. A # connected radio noise filter incorporating the choke is described (Fig. 2, not shown). |
