Bourns provides a recommended PCB layout and land pattern in their application notes and design guides. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
The power rating of the 91R1A-R22-B17L decreases as the temperature increases. Bourns provides a derating curve in the datasheet, which shows the maximum power rating at different temperatures. Engineers should consider this derating when designing their application.
The 91R1A-R22-B17L is a thick-film resistor, which is generally more resistant to moisture and humidity than thin-film resistors. However, it's still important to follow proper storage and handling procedures to prevent moisture absorption. Bourns recommends storing the resistors in a dry, cool place, and avoiding exposure to high humidity or moisture.
The 91R1A-R22-B17L is designed to meet the requirements of various industries, including automotive and industrial. While it can withstand some vibration and shock, it's essential to evaluate the specific application requirements and ensure the resistor is properly secured to the PCB. Bourns provides guidance on vibration and shock testing in their application notes.
The 91R1A-R22-B17L is a stable resistor with a low temperature coefficient of resistance (TCR). While it's designed to maintain its performance over time, it's still important to consider the effects of aging and environmental factors. Bourns provides information on the resistor's long-term stability and reliability in their application notes and reliability reports.
