SMW3180RJT - TE Connectivity

SMW3180RJT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the SMW3180RJT?
  TE Connectivity provides a recommended PCB layout and land pattern in their application note AN-1405, which can be found on their website. It's essential to follow these guidelines to ensure proper soldering and to prevent thermal issues.
• How do I handle the SMW3180RJT during assembly to prevent damage?
  Handle the component by the body, avoiding touching the leads or the thermal pad. Use anti-static wrist straps, mats, or packaging to prevent electrostatic discharge (ESD) damage. Avoid bending or flexing the leads, and use a pick-and-place machine or a vacuum pickup tool to minimize mechanical stress.
• What is the maximum allowable torque for the screw terminals on the SMW3180RJT?
  The maximum allowable torque for the screw terminals is 0.5 Nm (4.4 lb-in). Exceeding this torque can damage the terminals or the PCB. Use a torque-controlled screwdriver to ensure the correct torque is applied.
• Can I use the SMW3180RJT in a high-vibration environment?
  Yes, the SMW3180RJT is designed to withstand vibrations up to 10 G (98 m/s²) according to IEC 60068-2-6. However, it's essential to ensure the component is properly secured to the PCB and the PCB is rigid enough to prevent flexing or cracking.
• How do I ensure reliable wire connections to the SMW3180RJT screw terminals?
  Use stranded wire with a minimum of 1.5 mm² (16 AWG) cross-sectional area and a maximum of 2.5 mm (0.1 in) wire strip length. Apply a wire torque of 0.5 Nm (4.4 lb-in) and ensure the wire is securely fastened to the terminal. Use a wire with a suitable insulation rating for the operating temperature range.
