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.
Bourns offers a resistor selection guide that helps engineers choose the right resistor value and tolerance based on their specific application requirements, including power rating, operating temperature, and precision requirements.
According to Bourns, the maximum allowable voltage derating for the 1130-121K-RC is 150% of the rated voltage for a maximum of 5 seconds. However, it's recommended to consult the datasheet and application notes for specific derating guidelines.
While the 1130-121K-RC is a general-purpose resistor, it may not be the best choice for high-frequency applications due to its inductive properties. Bourns offers specialized high-frequency resistors, such as the CHV series, which are designed for high-frequency applications.
Bourns resistors are known for their high reliability and long lifespan. The 1130-121K-RC has a typical lifespan of 10,000 hours at 70°C, with a failure rate of less than 1% per 1,000 hours. However, the actual lifespan may vary depending on the application, operating conditions, and environmental factors.
