Abstract: A protection device may include a resistor, the resistor including a first end for coupling between a load and a second end for coupling to a DC source. The protection device may also include a capacitor having a first terminal coupled between the second end of the resistor and the DC source, and a second terminal coupled to ground, the capacitor further comprising a capacitor body, wherein the capacitor body comprises a ferroelectric material.

Abstract: A method of forming a positive temperature coefficient (PTC) device, the method including providing a core formed of a PTC material, the core having an electrode disposed on a first surface thereof and a second electrode disposed on a second surface thereof, connecting a first lead element to the first electrode, applying an oxygen barrier epoxy to at least portions of the core, the first electrode, the second electrode, and the first lead element, and curing the oxygen barrier epoxy to form an oxygen barrier package surrounding at least portions of the core, the first electrode, the second electrode, and the first lead element.

Abstract: A fuse suitable for arc quenching is disclosed. The fuse incorporates a high-resistive material or element placed in parallel relationship with the fusible element to mitigate, minimize and/or prevent arcing during an overcurrent condition. By incorporating a high-resistive material or element in parallel with a fusible element an alternate or second path for current flow during an overcurrent condition is provided. As such, during normal operating conditions, current travels through the fusible element. However, during an overcurrent condition, the resistance through the fusible element increases. Once the resistance through the fusible element is greater than the resistance through the high-resistive material or element, the current will bypass the fusible element and travel through the high-resistive material or element. In this manner, arcing through the fusible element during the overcurrent condition can be prevented or minimized.
