INDUCTOR
PROBLEM TO BE SOLVED: To provide an inductor which can suppress the vibration sound in a simple operation at a low cost even if the magnetic gap is large. SOLUTION: The center leg 1a of an E core 1 is shorter than the outside legs 1b, 1b, and not touching the I core 2, and a magnetic gap 10 is forme...

| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an inductor which can suppress the vibration sound in a simple operation at a low cost even if the magnetic gap is large. SOLUTION: The center leg 1a of an E core 1 is shorter than the outside legs 1b, 1b, and not touching the I core 2, and a magnetic gap 10 is formed between the E core 1 and the I core 2. The magnetic gap 10 is filled with a mixture 13 which has a coefficient of thermal expansion similar to these of the E core 1 and the I core 2, and is formed by mixing and curing high-heat-resistant nonmagnetic glass beads 11 and an adhesive 12. The diameters of the spherical glass beads 11 are ≥2/3 times to |
