Noise-cut LC filter for power converter with overlapping aligned coil patterns

摘要: A noise-cut filter having distributed inductances and capacitances is provided wherein conductive spiral coil patterns are formed on the opposite surfaces of a dielectric sheet, such that aligned with each other in direction perpendicular to plane main circuit pattern constructed by bonding conductor one sheet. The stamping punch press so has cross sectional area large enough allow passage current circuit, substantially same shape as pattern. Further, grounding wire bonded surface leads involving noises which flows from into via ground terminal.
