B1047AS-1R0N=P3 - Murata Electronics

B1047AS-1R0N=P3 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the B1047AS-1R0N=P3?
  The recommended land pattern for the B1047AS-1R0N=P3 can be found in the Murata Land Pattern Recommendation document, which provides detailed information on pad layout and dimensions for optimal assembly and reliability.
• How do I handle the B1047AS-1R0N=P3 inductor during PCB assembly to prevent damage?
  To prevent damage, handle the inductor by the body, avoiding touching the leads or core. Use anti-static wrist straps, mats, or packaging to prevent electrostatic discharge (ESD) damage. Follow standard PCB assembly procedures, and avoid bending or flexing the leads during component placement.
• What is the operating temperature range for the B1047AS-1R0N=P3?
  The operating temperature range for the B1047AS-1R0N=P3 is -40°C to +125°C, as specified in the datasheet. However, it's essential to consider the derating curves and temperature-related performance characteristics to ensure reliable operation in your specific application.
• Can I use the B1047AS-1R0N=P3 inductor in a high-frequency application?
  The B1047AS-1R0N=P3 is designed for general-purpose use, but it can be used in high-frequency applications up to several hundred kHz. However, it's crucial to consider the inductor's self-resonant frequency (SRF), which is around 100 MHz, and ensure that your application frequency is below the SRF to avoid unwanted resonances and losses.
• How do I determine the equivalent series resistance (ESR) of the B1047AS-1R0N=P3 inductor?
  The ESR of the B1047AS-1R0N=P3 is not explicitly stated in the datasheet. However, you can estimate the ESR by using the inductor's DC resistance (Rdc) and the impedance (Z) at a specific frequency. Murata provides a formula to calculate ESR in their application notes and technical documentation.
