Ohmite Launches FCSL Series: Precision Current Sensing Breakthrough
Arlington Heights, Friday, 18 October 2024.
Ohmite’s new FCSL Series resistors employ metal foil technology for superior current sensing in power electronics. Featuring low TCRs and ohmic values down to 1 mΩ, they offer high precision and stability for critical current measurement applications.
Innovative Features and Technology
The FCSL Series represents a significant advancement in current sensing technology, due to its incorporation of metal foil, which offers a stable and low Temperature Coefficient of Resistance (TCR) down to 50 parts per million (ppm). This attribute ensures that the resistors maintain their precision even with temperature variations, thus making them ideal for use in environments where thermal stability is crucial. Moreover, the series provides a wide range of very low ohmic values, starting from 1 milli-Ohm, and supports power ratings up to 10 Watts, which broadens its applicability across various high-power applications[1].
Performance Comparison and Use Cases
When compared to other current sense resistors, the FCSL Series stands out for its low TCR and high precision, which are essential for applications such as power management in electronics and electrical engineering devices. This series is also available in a 4-terminal version, the FC4L, which can enhance measurement accuracy by minimizing the impact of lead resistance. Such features make the FCSL Series particularly beneficial for applications in sectors like telecommunications, automotive electronics, and industrial equipment, where precise current measurement is critical[1][2].
Pros, Cons, and Recommendations
A notable advantage of the FCSL Series is its ability to deliver high accuracy and stability in current measurement, which is crucial for precise power management. However, one potential drawback could be its cost, which might be higher compared to traditional thick film resistors used for general purposes. For users in need of precise current sensing and management, especially in high-power or temperature-sensitive environments, the FCSL Series is highly recommended. On the other hand, for applications where cost is a primary concern and extreme precision is not necessary, alternatives like thick film resistors may be more appropriate[2][3].
Conclusion and Future Outlook
The introduction of the FCSL Series by Ohmite marks a milestone in the field of current sensing technology, offering enhanced precision and stability for demanding applications. As electronic devices continue to evolve, the need for such advanced components will likely increase, making the FCSL Series a valuable addition to the toolkit of engineers and designers aiming for high-performance solutions. As Ohmite continues to expand its product offerings, the FCSL Series is poised to set new standards in the industry[1][2].
