PSK-20D-5 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended. Additionally, a thermal pad on the bottom of the device should be connected to a heat sink or a thermal management system.
• How do I ensure reliable soldering and avoid damage during the assembly process?
  CUI recommends following the recommended soldering profile and using a solder with a melting point below 240°C. Avoid applying excessive force or pressure during assembly, and ensure the device is handled by the edges to prevent damage to the pins or internal components.
• What is the maximum operating temperature range for the PSK-20D-5?
  While the datasheet specifies an operating temperature range of -40°C to 100°C, CUI recommends derating the device for reliable operation above 85°C. Consult with CUI's application engineers for specific guidance on high-temperature applications.
• Can I use the PSK-20D-5 in a high-vibration or high-shock environment?
  Yes, the PSK-20D-5 is designed to withstand moderate vibration and shock. However, CUI recommends following the recommended PCB mounting and screw torque specifications to ensure reliable operation in harsh environments.
• What are the EMI and RFI considerations for the PSK-20D-5?
  The PSK-20D-5 is designed to meet CISPR 22 Class B emissions standards. CUI recommends following proper PCB layout and shielding techniques to minimize EMI and RFI. Additionally, ensure the device is properly grounded and decoupled to prevent noise coupling.
