IHLP1212AEERR47M11 - Vishay

IHLP1212AEERR47M11 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the IHLP1212AEERR47M11?
  The recommended land pattern for the IHLP1212AEERR47M11 is a rectangular pad with a size of 3.3 mm x 2.5 mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the inductor's thermal derating?
  The IHLP1212AEERR47M11 has a temperature derating curve specified in the datasheet. To handle thermal derating, ensure that the inductor's operating temperature is within the specified range, and consider using a heat sink or thermal interface material if necessary.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the IHLP1212AEERR47M11 is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Typically, the SRF is around 100-200 MHz for this inductor.
• Can I use the IHLP1212AEERR47M11 in a high-frequency application?
  While the IHLP1212AEERR47M11 is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the inductor's self-resonant frequency and core losses. Consider using a different inductor or evaluating the inductor's performance at the specific frequency of interest.
• How do I ensure the inductor's reliability and prevent failure?
  To ensure reliability, follow proper PCB design and layout guidelines, avoid overheating, and ensure the inductor is operated within its specified ratings. Also, consider using a fuse or overcurrent protection to prevent damage from excessive current.
