0402DC-47NXJRW - COILCRAFT

0402DC-47NXJRW Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  Coilcraft provides a recommended land pattern for the 0402DC series, which can be found in the 'Packaging Information' section of the datasheet or on the Coilcraft website. The recommended land pattern ensures optimal performance and reliability.
• How do I handle the inductor's sensitivity to PCB layout and proximity to other components?
  To minimize the impact of PCB layout and proximity to other components, follow best practices for high-frequency PCB design, such as keeping the inductor away from other components, using a solid ground plane, and minimizing trace lengths and widths. Additionally, consider using a shield or guard trace to reduce electromagnetic interference (EMI).
• What is the maximum operating temperature range for this inductor?
  The 0402DC-47NXJRW inductor has an operating temperature range of -40°C to +125°C, which is suitable for most commercial and industrial applications. However, it's essential to consider the specific operating conditions and ensure the inductor is within its rated temperature range to maintain reliability and performance.
• How do I determine the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 0402DC-47NXJRW inductor is not explicitly stated in the datasheet. However, Coilcraft provides an SRF calculator tool on their website, which can be used to estimate the SRF based on the inductor's characteristics and the PCB layout.
• What is the inductor's tolerance on the inductance value?
  The 0402DC-47NXJRW inductor has a tolerance of ±5% on the inductance value, which means the actual inductance may vary by up to 5% from the nominal value. This tolerance is typical for most inductors and should be considered when designing the circuit.
