The RNWA’s wide terminations effectively reduce hot spot temperatures, filling a crucial gap in the market for precision and high-reliability resistors.
Stackpole introduces the RNWA, a thin-film chip resistor that merges the advantages of wide terminations with exceptional precision and reliability. The RNWA achieves tolerances as low as 0.1% and a temperature coefficient of resistance (TCR) down to 25 ppm. It is automotive grade, providing enhanced long-term stability and resistance to sulfur, making it ideal for demanding applications.
Key Features:
- Precision tolerances to ±0.1%
- TCR down to ±25 ppm/ºC
- Wide resistance value range
Surface-mount chip resistors employed in high-power applications frequently encounter elevated circuit temperatures due to the constraints imposed by thermal resistance. A common and effective solution to alleviate these thermal issues is the use of wide terminations. These wide terminations can significantly decrease the hot spot temperature of a chip by approximately 30% to 40%. However, there is a notable scarcity of wide termination chip resistors that cater to applications demanding precision tolerance, tight Temperature Coefficient of Resistance (TCR), or high reliability. The RNWA series addresses this deficiency by providing wide terminations alongside high precision, thus fulfilling the needs of these demanding applications.
In addition to its thermal and precision benefits, the RNWA series boasts several compliance and quality certifications. It is RoHS-compliant, ensuring it meets the standards for the restriction of hazardous substances. It is also REACH-compliant, which means it adheres to regulations concerning the registration, evaluation, authorization, and restriction of chemicals. Furthermore, the RNWA series is lead-free and halogen-free, making it a safer and more environmentally friendly option. To top it off, the RNWA meets the rigorous AEC-Q200 qualification standards, which is crucial for automotive applications.
The pricing for the RNWA series varies depending on the specific size, tolerance, and TCR specifications required by the user. This variability in pricing allows the RNWA to accommodate a wide range of needs and budgets, making it a versatile choice for high-power applications requiring precise and reliable surface-mount chip resistors.
