SR4M4012 Frequently Asked Questions (FAQs)

  • TE Connectivity recommends a 4-layer PCB with a solid ground plane and a separate power plane for the module. The PCB should also have a low-ESR capacitor (e.g., 10uF) connected between the power pins (VIN and GND) to filter out noise.
  • To ensure reliable operation in high-temperature environments, it is recommended to derate the module's output current and voltage according to the temperature derating curve provided in the datasheet. Additionally, ensure good airflow around the module and consider using a heat sink if necessary.
  • TE Connectivity recommends keeping the input and output cable lengths as short as possible, but not exceeding 10 inches (25 cm) to minimize signal degradation and electromagnetic interference (EMI).
  • Yes, the SR4M4012 can be used in a redundant or parallel configuration to achieve higher power output. However, it is essential to ensure that the modules are synchronized and properly configured to avoid oscillations and instability.
  • The SR4M4012 is designed to meet CISPR 22 and FCC Part 15 Class B emissions standards. To minimize EMI and RFI, ensure proper PCB layout, use shielded cables, and consider adding EMI filters or shielding to the module and surrounding components.
