Abstract: A resin-made base body 1 has first recessed portions 11 and 12 for respectively accommodating a plurality of pulse transformers as well as second recessed portions 13 and 14 for accommodating common mode choke coils which are respectively connected to the pulse transformers. The first recessed portions 11 and 12 are formed on one terminal fixing edge 7 side of the base body 1. The second recessed portions 13 and 14 are formed on the other terminal fixing edge 10 side. The first recessed portions 11 and 12 and the second recessed portions 13 and 14 are arranged by being longitudinally connected in a direction from the one terminal fixing edge 7 toward the other terminal fixing edge 10. The adjacent first recessed portions 11 and 12 are connected at one end portion, and the adjacent second recessed portions 13 and 14 are also formed by being connected at one end portion. Thus, provided are a package for parts for LAN and a module for LAN which is miniaturized, and the insertion loss is reduced.

Abstract: A first terminal block having first terminals to be in contact with terminals of a plug is incorporated in a housing. The first terminals are exposed to an internal space portion 1e of the housing, while the rear ends of the first terminals project at the rear of the block. A second terminal block has second terminals to be connected to a motherboard the modular jack should be attached to. Electronic parts a are mounted on an internal board. The internal board includes through-hole-like terminals or notch-like terminals to which the first and second terminals and should be soldered. Winding terminals of winding parts are inserted and soldered to through holes of the internal board.

Abstract: A first terminal block 3 having first terminals 2 to be in contact with terminals of a plug is incorporated in a housing 1. The first terminals 2 are exposed to an internal space portion 1e of the housing 1, while the rear ends of the first terminals 2 project at the rear of the block 3. A second terminal block 5 has second terminals 4 to be connected to a motherboard the modular jack should be attached to. Electronic parts 7a and 7b are mounted on an internal board 6. The internal board 6 includes through-hole-like terminals 6a and 6b or notch-like terminals to which the first and second terminals 2 and 4 should be soldered. Winding terminals 8 of winding parts are inserted and soldered to through holes 6c and 6d of the internal board 6.
