    Abstract: A rate of change of current sensor includes two measurement coils, arranged such that the turns of the first and second measurement coils are interleaved. The rate of change of current sensor further comprises two return coils, arranged to progress in an opposite direction to the measurement coils. The coils form loops and progress substantially around a target measurement conductor. This ensures that the two measurement coils both receive the same electrostatic coupling from external conductors which are not the target of the measurement operation. Further, the two measurement coils are arranged such that the first coil and the second coil are, on average, the same distance to the current-carrying conductor of interest.

  • Patent number: 11894177
    Abstract: In an electronic component, a terminal electrode has a thickest portion and a part thinner than the thickest portion. Accordingly, an increase in solder fillet forming region occurs when the electronic component is solder-mounted onto a predetermined mounting substrate. In the electronic component, mounting strength is improved as a result of the increase in solder fillet forming region. In addition, in the electronic component, the thickest portion overlaps a bump electrode in a direction orthogonal to the lower surface of an element body. Accordingly, the impact that is applied to the electronic component during the mounting onto the mounting substrate is reduced and the impact resistance of the electronic component is improved.
