S1812-103K datasheet by API Delevan

S1812-103K Frequently Asked Questions (FAQs)

• What is the recommended land pattern for S1812-103K?
  The recommended land pattern for S1812-103K is a rectangular pad with a size of 1.3mm x 0.8mm, with a non-solder mask defined (NSMD) pad shape. This ensures proper soldering and minimizes the risk of solder bridging.
• Can I use S1812-103K in high-frequency applications?
  Yes, S1812-103K is suitable for high-frequency applications up to 1 GHz. However, it's essential to consider the inductor's self-resonant frequency (SRF) and ensure that it does not interfere with the operating frequency of your circuit.
• How do I handle the inductor's magnetic field in a densely populated PCB?
  To minimize the impact of the inductor's magnetic field, consider the following: keep the inductor away from sensitive components, use a shielded inductor or a mu-metal shield, and orient the inductor to minimize the magnetic field's effect on nearby components.
• What is the maximum operating temperature for S1812-103K?
  The maximum operating temperature for S1812-103K is 125°C. Exceeding this temperature may affect the inductor's performance, reliability, and lifespan.
• Can I use S1812-103K in a high-current application?
  S1812-103K is rated for a maximum current of 1.3A. Exceeding this current may cause the inductor to overheat, leading to reduced performance, reliability issues, or even failure. Consider using a higher-current-rated inductor or derating the current to ensure safe operation.
