ABSTRACT:
A circuit module, such as is used in a modular L-C filter, includes a support having a base portion and side portions. One or more electric circuit elements, such as inductors and capacitors, are mounted on the support. One of the side portions of the support is provided with an externally exposed recess which is adapted to at least partially receive an interconnecting element such as a coupling coil. Thus, two of the modules can be located on a circuit board in adjacent relationship with the recesses therein aligned to form a cavity in which the coupling coil is received, the coil itself preferably being independently mounted on the circuit board. In this manner, the amount of space required by the filter is substantially reduced.
