Disclosed herein is a common mode filter that includes a winding core part and first and second wires wound in a same direction around the winding core part. The first and second wires constitute a first winding block on one endmost side in an axial direction of the winding core part, a second winding block on other endmost side in the axial direction of the winding core part, and a third winding block positioned between the first and second winding blocks. The second winding block is a winding block at an odd-numbered position counted from the first winding block. The first and second wires cross each other in an area between the first and third winding blocks and in an area between the second and third winding blocks.

An LC filter arrangement includes a filter capacitor that connects the first output terminal to the second output terminal, a magnetic core, and a choke having a plurality of turns surrounding the magnetic core, and a first choke terminal and a second choke terminal. Each of the turns is formed by a separate conductor segment, at least partially surrounding the magnetic core. The LC filter arrangement is mounted on a circuit board and is electrically connected to a conductor track of the circuit board.

A wavetrap includes a housing having a base including a base plate. The housing has a wire channel, an inductor pocket and a terminal pocket. The housing has a capacitor pocket that receives a capacitor. The wavetrap includes a defroster wire having a wire end received in the wire channel.

A half-bride combiner can be implemented as a coupling circuit having a common node and configured to couple the common node to one of first and second groups of filters through a first path and to couple the common node to the other group through a second path. The coupling circuit can be further configured such that the impedance provided by each filter of the one of the first and second groups for a signal in each band of the other group results in the signal being sufficiently excluded from the first path.

A power noise filter and a supply modulator including the same, and a wireless communication device including the power noise filter are provided. The power noise filter includes a band stop filter and a low pass filter. The band stop filter includes an inductor and a first capacitor, which are connected in parallel between first and second nodes. The first node receives a first voltage, which is filtered by the band pass filter to thereby generate a second voltage at the second node. The first low pass filter includes the inductor and a second capacitor, which has one end connected to the second node and an opposite end connected to a ground source.

The disclosure relates to an electrical component, for example, a surface-mount resonator, including a distributed-element circuit disposed on a dielectric base and separated from an electromagnetic field modification member by a gaseous gap, wherein a frequency characteristic of the electrical component can be tuned by positioning the electromagnetic field modification member relative to the distributed-element circuit using an actuator.

A multilayer substrate includes a stacked body including a first main surface, and a conductor pattern (including a mounting electrode provided on the first main surface, and a first auxiliary pattern provided on the first main surface). The stacked body includes a plurality of insulating base material layers made of a resin as a main material and stacked on one another. The first auxiliary pattern is located adjacent to or in a vicinity of the mounting electrode. The mounting electrode, in a plan view of the first main surface (when viewed in the Z-axis direction), is interposed between a different conductor pattern (the mounting electrode) and the first auxiliary pattern.
