Bourns recommends a symmetrical PCB layout with the resistor centered between the power planes to minimize inductive coupling and ensure optimal performance. A minimum of 0.5 mm clearance around the resistor is recommended to prevent thermal and electrical interference.
The 91R1A-R22-B10L is designed to handle high-frequency signals up to 1 GHz. However, it's essential to consider the skin effect and proximity effect at high frequencies, which may affect the resistor's performance. Bourns recommends using a high-frequency simulation tool to optimize the design.
The maximum power rating of the 91R1A-R22-B10L decreases with increasing temperature. At 125°C, the maximum power rating is approximately 60% of the rated power at 25°C. Consult the datasheet or contact Bourns for specific derating information.
Yes, the 91R1A-R22-B10L is suitable for high-reliability and aerospace applications. Bourns offers a range of high-reliability resistors that meet the requirements of MIL-PRF-55342 and other industry standards. However, it's essential to consult with Bourns or a qualified distributor to ensure the specific product meets the application's requirements.
The 91R1A-R22-B10L is designed to operate in harsh environmental conditions, including high humidity and vibration. However, it's essential to follow proper mounting and soldering techniques to ensure the resistor's performance and reliability. Consult the datasheet or contact Bourns for specific environmental testing information.
