a) EP-cores are primari y u ed f or in u tors an tran formers, but they can also b u ed f or

b) EP-cores, ex e t f or EP5-cores, are esp cial y s ited f or u e on printed wirin b ard ,

b cau e it is p s ible to solder the wire le d of the cois directly to the pin terminals

in erted into the coi f ormer Normal y, these pin s ould remain within the outl ne of the

c) The b se are s, ex e t f or EP5-cores, are s uare an the win in sp ce is an ular
