Title:
NOISE FILTER MOUNTING SUBSTRATE
Document Type and Number:
Japanese Patent JP3868386
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a noise filter mounting substrate wherein high-frequency noise produced by a load circuit is sufficiently attenuated.
SOLUTION: The noise filter mounting substrate is for supplying direct- current power to a load circuit (20) from a power source and for separating a power line circuit from the load circuit which produces high-frequency noise in terms of high frequency. The noise filter mounting substrate comprises a circuit board (6) and a noise filter (1). A power line conductor layer (7a) can be connected to the power source. A ground conductor layer (8a) can be grounded. The noise filter mounting substrate further comprises an output power supply conductor (7b) and an output ground conductor (8b) which are connected with fourth and third conductor lands (16, 15), and for connecting the fourth and third conductor lands (16, 15) to the load circuit (20) without connection with the power line conductor layer (7a) or the ground conductor layer (8a).
