Bourns recommends a symmetrical PCB layout with a solid ground plane to minimize electromagnetic interference (EMI) and ensure optimal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
The 91R1A-R22-B12L has a maximum operating temperature of 125°C. Ensure proper thermal management by providing adequate airflow, using thermal vias, and keeping the component away from heat sources. A thermal pad or heat sink may be necessary for high-power applications.
Bourns recommends a reflow soldering process with a peak temperature of 260°C (500°F) for a maximum of 20 seconds. Hand soldering is not recommended due to the component's small size and high thermal mass.
To ensure reliability in high-vibration environments, Bourns recommends using a secure mounting method, such as a screw-down or adhesive mounting, and ensuring the component is properly secured to the PCB. Additionally, consider using a vibration-dampening material or potting the component.
The 91R1A-R22-B12L is sensitive to electrostatic discharge (ESD). Handle the component with ESD-protective equipment, such as wrist straps and mats, and ensure the PCB is properly grounded. Avoid touching the component's pins or body to prevent ESD damage.
