3290W-1-200 - Bourns

3290W-1-200 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the 3290W-1-200?
  Bourns recommends a symmetrical PCB layout with a ground plane underneath the device to minimize electromagnetic interference (EMI) and ensure optimal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
• How do I ensure the 3290W-1-200 is properly soldered to the PCB?
  Bourns recommends using a soldering iron with a temperature of 250°C to 260°C and a solder with a melting point of 180°C to 190°C. The device should be soldered within 3 seconds to 5 seconds, and the solder joints should be inspected for proper wetting and filleting.
• What is the maximum operating temperature range for the 3290W-1-200?
  The 3290W-1-200 is rated for operation from -40°C to 125°C, but derating is required for temperatures above 85°C. Consult the datasheet for specific derating curves.
• Can the 3290W-1-200 be used in high-vibration applications?
  Yes, the 3290W-1-200 is designed to withstand high-vibration environments. However, it's essential to ensure the device is properly secured to the PCB and the PCB is properly mounted to the system to prevent mechanical stress.
• Is the 3290W-1-200 compatible with lead-free soldering processes?
  Yes, the 3290W-1-200 is compatible with lead-free soldering processes. Bourns uses a lead-free termination finish that meets the requirements of the RoHS directive.
