A noise filter includes: a noise detection unit which detects a common mode noise; a cancellation signal output unit; an injection unit which injects a cancellation signal; and a grounded capacitor. The cancellation signal output unit includes a filter part which generates the cancellation signal from the common mode noise, and an amplification part which amplifies the cancellation signal. A temperature dependence of a product of an inductance value and a capacitance value of a main circuit portion including the noise detection unit, the injection unit, and the grounded capacitor, and a temperature dependence of a product of an inductance value and a capacitance value of the filter part, are equal to each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Noise filter","description":"Provided is a low-cost noise filter having a noise suppression effect that is not reduced even when a resonance frequency changes according to changes in temperature.
