PTL60-10G1-103B2 - Bourns

PTL60-10G1-103B2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical layout with the transformer centered on the PCB, and a solid ground plane on the bottom layer. This helps to reduce electromagnetic interference (EMI).
• How do I ensure proper insulation and creepage distance?
  Maintain a minimum of 1.5 mm distance between the transformer pins and any other components or conductive paths on the PCB. Also, ensure that the transformer is properly insulated from the PCB using a suitable insulating material, such as a thin layer of FR4 or a dedicated insulating washer.
• What is the maximum operating temperature range for this transformer?
  The PTL60-10G1-103B2 is rated for operation from -40°C to +125°C, with a maximum storage temperature range of -55°C to +150°C.
• How do I handle the transformer's magnetization current during startup?
  To prevent inrush current issues, use a soft-start circuit or an NTC thermistor in series with the transformer primary. This helps limit the inrush current and prevents damage to the transformer or other components.
• What is the recommended wire gauge for connecting the transformer?
  Bourns recommends using a minimum of 24 AWG wire for connecting the transformer, with a maximum length of 10 cm (4 inches) to minimize parasitic inductance and resistance.
