SDR1105-180ML - Bourns

SDR1105-180ML Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns provides a recommended PCB layout and land pattern in their application note AN204, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance and minimize parasitic effects.
• How do I handle the high current rating of the SDR1105-180ML in my design?
  To handle the high current rating, ensure that your PCB design includes adequate copper thickness and width to handle the current. Additionally, consider using multiple vias to connect the pads to the internal layers, and use thermal vias to dissipate heat. It's also crucial to follow proper thermal management and heat sinking techniques.
• What is the maximum operating temperature range for the SDR1105-180ML?
  While the datasheet specifies an operating temperature range of -40°C to 150°C, it's essential to note that the device's performance and reliability may degrade at extreme temperatures. It's recommended to operate the device within a temperature range of -20°C to 125°C for optimal performance and reliability.
• How do I ensure the SDR1105-180ML is properly soldered and reflowed?
  Follow the recommended soldering and reflow profile provided in the datasheet. Ensure that the PCB is designed with adequate solder mask and clearance to prevent solder bridging. It's also crucial to use a solder with a high melting point and to follow proper soldering techniques to prevent damage to the device.
• What are the ESD protection and handling requirements for the SDR1105-180ML?
  The SDR1105-180ML is a sensitive device and requires proper ESD protection and handling. Ensure that your production line and handling procedures follow proper ESD protection guidelines, such as using ESD-safe materials, wrist straps, and mats. It's also recommended to handle the devices in a controlled environment with minimal humidity and temperature fluctuations.
