Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure proper mounting and to minimize thermal resistance.
Proper thermal management is crucial for the 91R1A-R22-B25L. Ensure good airflow around the component, and consider using a heat sink or thermal interface material (TIM) to reduce thermal resistance. Bourns also recommends following the guidelines in their application note AN164 for thermal management.
The maximum operating temperature range for the 91R1A-R22-B25L is -40°C to +150°C. However, it's essential to note that the component's performance and reliability may degrade at higher temperatures, so it's recommended to operate within a narrower temperature range if possible.
The 91R1A-R22-B25L is designed to withstand moderate vibration levels. However, if your application involves extreme vibration, it's recommended to consult with Bourns or perform additional testing to ensure the component's reliability and performance.
Bourns recommends following the soldering guidelines in their application note AN164, which includes using a soldering iron with a temperature range of 250°C to 260°C, and a soldering time of 3-5 seconds. It's also essential to use a solder with a melting point above 217°C.
