1229AS-H-6R8M=P3 - Murata Electronics

1229AS-H-6R8M=P3 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 1229AS-H-6R8M=P3 inductor is a rectangular pad with a size of 1.2mm x 0.9mm, with a non-solder mask defined (NSMD) pad shape. This ensures proper soldering and minimizes the risk of solder bridging.
• Can I use this inductor in a high-temperature environment?
  The 1229AS-H-6R8M=P3 inductor is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation. Consult the datasheet and Murata's application notes for more information.
• How do I handle the inductor's magnetic field in my design?
  To minimize the impact of the inductor's magnetic field, keep the inductor at least 2mm away from sensitive components, such as oscillators, antennas, and magnetometers. You can also use shielding techniques, like copper pours or magnetic shields, to contain the field.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the 1229AS-H-6R8M=P3 inductor is approximately 250MHz. This is the frequency at which the inductor's impedance peaks due to its internal capacitance and inductance. Be cautious when operating near this frequency to avoid unwanted resonances.
• Can I use this inductor in a high-current application?
  The 1229AS-H-6R8M=P3 inductor is rated for a maximum current of 1.2A. While it can handle high currents, it's essential to consider the inductor's power dissipation, temperature rise, and saturation characteristics to ensure reliable operation.
