A packaged multichip isolation device includes leadframe including a first and second die pad, with a first and second lead extending outside a molded body having a downward extending lead bend near their outer ends. A first integrated circuit (IC) die on the first die pad has a first bond pad connected to the first lead that realizes a transmitter or receiver. A second IC die on the second die pad has a second bond pad connected to the second lead that realizes another of the transmitter and receiver. An isolation component is in a signal path of the isolation device including a capacitive isolator, or inductors for transformer isolation on or between the die. A midpoint of the thickness of the die pad is raised above a top level of the leads and in an opposite vertical direction relative to the downward extending bend of the external leads.

Disclosed herein is a differential mode filter that includes first and second terminal electrodes provided on a first flange part of a core, and first and second wires wound around a winding core part of the core in an opposite direction to each other and connected respectively to the first and second terminal electrodes. The first and second wires cross each other on the winding core part to form a plurality of crossing portions that include first, second, and third crossing portions that are first, second, and third occurrences counting from the one end of the first and second wires, respectively. A first crossing angle between the first and second wires at the first crossing portion is larger than at least one of second and third crossing angles between the first and second wires at the second and third portions, respectively.

The present invention relates to a remotely triggered improved electrical stimulus circuit to be worn by cattle that is lightweight and can store voltage lower than what is to be supplied to an animal. Known cattle electrical stimulus collars may be heavy, use a lot of energy, and not supply a consistent electrical stimulus. The present electrical stimulus circuit utilizes feedback loops to allow the use of high tolerance lightweight capacitors, and/or cool down periods to utilize a highly inefficient transformer running fully saturated.
