Current-sensing techniques are intrusive, meaning that somehow they will affect the system performance. It’s usually necessary to insert “something” in the middle of the path that goes from the power source to the load through which the current that we need to monitor flows.

Resistor engineers designed to mitigate these losses must use current sensor resistors with low resistive values. This is the greatest complexity of this method, choosing the better resistor to obtain a balance between precision, energy loss, and costs in the current sensor

Power Distribution Unit (PDU) in a satellite aims to distribute energy across all subsystems and payloads and prevent the overload of the main power bus. The design of a PDU seeks efficient functionality, achieving a balance of performance, weight and reliability, meeting the mission requirements at the lowest possible cost without risk.

Stackpole’s CSS0508 is a one-watt current sense chip resistor that combines high power in a small package, low resistance values, and low TCR in a robust all-metal technology. In addition, the 0508 long side termination allows the part to run cooler under full rated power than similar size chips because the larger terminations are far more thermally efficient.

Low resistance values are important for high efficiency current sensing in that lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values becomes challenging because of lead resistance. Using a four terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation.

New Space is a business that has come pushing hard on the past years. With the development of mega-constellations as Iridium or OneWeb and the entrance of new companies from industry on Space business related to telecommunications, a relaxation on the classical requirements for space parts has come to this market.
