SDR1105-820KL - Bourns

SDR1105-820KL Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the SDR1105-820KL?
  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 proper thermal management and to minimize parasitic inductance.
• How do I select the correct current rating for my application?
  To select the correct current rating, consider the maximum current required by your circuit, taking into account any potential inrush currents or surges. Also, consider the operating temperature range and the desired level of derating. Bourns provides a current rating selection guide in their datasheet, which can help with this process.
• What is the maximum operating temperature range for the SDR1105-820KL?
  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 higher temperatures. Bourns recommends derating the current rating at higher temperatures to ensure reliable operation.
• Can I use the SDR1105-820KL in a high-vibration environment?
  Yes, the SDR1105-820KL is designed to withstand high-vibration environments. However, it's crucial to ensure that the device is properly mounted and secured to the PCB to prevent mechanical stress and damage. Bourns provides guidelines for mounting and securing the device in their application note AN204.
• How do I handle ESD protection when working with the SDR1105-820KL?
  To prevent electrostatic discharge (ESD) damage, follow proper ESD handling procedures when working with the SDR1105-820KL. This includes using ESD-safe workstations, wrist straps, and packaging materials. Bourns also recommends using ESD protection devices, such as TVS diodes, in the circuit design.
