DD1274AS-H-2R2N=P3 Frequently Asked Questions (FAQs)

  • Murata recommends a land pattern with a minimum pad size of 1.5mm x 1.5mm and a spacing of 0.5mm between pads to ensure reliable soldering and minimize thermal resistance.
  • The inductor's thermal derating is specified in the datasheet. To handle it, ensure that the operating temperature is within the recommended range, and consider using a heat sink or thermal interface material to reduce the temperature rise.
  • The SRF of the DD1274AS-H-2R2N=P3 is not explicitly stated in the datasheet. However, according to Murata's application notes, the SRF can be estimated using the inductor's inductance value and the parasitic capacitance. For this specific part, the SRF is approximately 150 MHz.
  • While the DD1274AS-H-2R2N=P3 is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the inductor's parasitic capacitance and resistance. It's essential to evaluate the inductor's behavior in your specific application and consider using a more suitable inductor if necessary.
  • To ensure reliability, follow Murata's recommended storage and operating temperature ranges. Additionally, consider using a conformal coating or potting compound to protect the inductor from moisture and mechanical stress.
