46102C - Murata Electronics

46102C Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Murata recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is also recommended.
• How do I ensure the DC-DC converter's reliability in high-temperature environments?
  To ensure reliability in high-temperature environments, make sure to follow the recommended derating guidelines, use a suitable thermal interface material, and provide adequate airflow around the converter. Additionally, consider using a heat sink or a thermal pad to dissipate heat.
• What is the maximum capacitance value for the input and output capacitors?
  The maximum capacitance value for the input and output capacitors is not explicitly stated in the datasheet. However, as a general guideline, Murata recommends using capacitors with a maximum value of 10uF for the input and 22uF for the output.
• Can I use the 46102C in a redundant or parallel configuration?
  Yes, the 46102C can be used in a redundant or parallel configuration to achieve higher power ratings or to improve reliability. However, it's essential to follow Murata's guidelines for parallel and redundant operation, and to ensure that the converters are properly synchronized and monitored.
• What is the recommended EMI filter configuration for the 46102C?
  Murata recommends using a pi-filter configuration (L-C-L) with a common-mode choke and X-capacitors to minimize EMI emissions. The filter component values should be selected based on the specific application and the desired level of EMI attenuation.
