Thin Film Technology Corp. has conducted a detailed study of current flow within the CSR circuit that demonstrates the advantages and disadvantages of various CSR topologies. This paper will deliver information that allows electronics designers to create low ohmic current sense circuitry that is more efficient and more accurate.
It is important when designing a circuit to know how to select the best component for your application. The team at Thin Film Technology (TFT) can guide you in this journey. The article below will discuss what is parasitic inductance and ESL, other factors to understand when evaluating the parasitic inductance of a resistor, and the recommended components to begin your search.
Having a high reliable Current Sense Resistor (CSR) component in your design is always a priority for a successful output. However, the value of this component will be diminished if you do not have a good optimization of your PCB. The more you minimize your design error contributions, the more superior performance you will achieve. This paper will discuss some of the factors to consider when designing a PCB.
This paper will review the differences between 2-terminal current sensing resistors mounted to a 4-wire land pattern and 4-terminal current sensing resistors mounted to a 4-wire land pattern. It will then explain why, even with the slightly higher price, 4-terminal resistors are the better choice.
The purpose of this paper is to show the significance of Temperature Coefficient of a Resistance (TCR) in ultra-high precision current sense resistors and how it can fundamentally change an electrical circuit functionality.

Four-terminal resistors contribute to measurement accuracy, and various designs exist for their construction. Resistors such as Thin Film Technology Corp’s (TFT) CPA series perform better in high power applications due to its high heat dissipation capabilities. A study by TFT’s engineers investigated the factors that contribute to variations in resistance following the mounting of the component to a PCB.
In the realm of electrical engineering, the terms “shunts” and “current sensing shunts” are often used interchangeably, leading to confusion. However, it’s essential to recognize that a current sensing shunt serves a specific purpose within the broader category of shunts. Let’s delve into the distinction and shed light on the significance of current sensing shunts in modern electrical systems.
