IT238 Frequently Asked Questions (FAQs)

  • Schaffner recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to ensure efficient heat transfer.
  • IT238 is designed to filter out high-frequency noise and EMI through its proprietary filter technology, which includes a combination of inductive and capacitive components to provide high attenuation across a wide frequency range.
  • The maximum operating temperature range for IT238 is -40°C to +85°C, with a derating of 1.5% per Kelvin above 70°C.
  • Yes, IT238 is designed to meet the requirements of safety-critical applications, including IEC 61508 and IEC 62368, and is certified to UL 60950-1 and EN 60950-1.
  • IT238 is designed to withstand overvoltage and overcurrent conditions through its built-in overvoltage protection (OVP) and overcurrent protection (OCP) circuits, which provide protection against voltage surges and current spikes.
