PLT10HH501100PNB - Murata Electronics

PLT10HH501100PNB Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the PLT10HH501100PNB?
  Murata provides a recommended PCB land pattern in their datasheet, but it's also available on their website. The recommended land pattern is a rectangular shape with dimensions of 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the inductor's terminal.
• How do I handle the PLT10HH501100PNB's thermal considerations?
  The PLT10HH501100PNB has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management during PCB design. This includes providing adequate spacing between components, using thermal vias, and selecting a suitable PCB material with high thermal conductivity.
• What is the PLT10HH501100PNB's saturation current rating?
  The saturation current rating of the PLT10HH501100PNB is not explicitly stated in the datasheet. However, according to Murata's application notes, the inductor's saturation current can be estimated by using the following formula: Isat = (L × Irms) / (L × ΔL / L). Where L is the inductance, Irms is the RMS current, and ΔL / L is the inductance variation ratio.
• Can I use the PLT10HH501100PNB in a high-frequency application?
  The PLT10HH501100PNB is designed for high-frequency applications, with a self-resonant frequency of 100 MHz. However, it's essential to consider the inductor's impedance characteristics and ensure that it meets the specific requirements of your application. Murata provides impedance vs. frequency graphs in the datasheet to aid in this evaluation.
• How do I ensure the PLT10HH501100PNB is properly soldered to the PCB?
  To ensure reliable soldering, follow Murata's recommended soldering conditions: peak temperature of 260°C, soldering time of 3 seconds, and a soldering iron temperature of 350°C. Additionally, use a solder with a melting point above 217°C, and ensure the PCB is designed with adequate solder pads and thermal reliefs.
