SPM3015T-4R7M - TDK

SPM3015T-4R7M Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the SPM3015T-4R7M?
  The recommended land pattern for the SPM3015T-4R7M can be found in the TDK Corporation's application note or on their website. It typically includes a rectangular pad with a size of 1.5mm x 1.5mm and a thermal via to ensure good thermal dissipation.
• How do I handle the SPM3015T-4R7M inductor during PCB assembly?
  The SPM3015T-4R7M inductor should be handled with care during PCB assembly to avoid mechanical stress, which can cause damage to the component. It is recommended to use a vacuum pick-up tool or a soft-tipped tweezers to handle the component, and to avoid bending or flexing the leads.
• What is the maximum operating temperature range for the SPM3015T-4R7M?
  The maximum operating temperature range for the SPM3015T-4R7M is -40°C to +125°C, as specified in the datasheet. However, it's recommended to derate the component's current rating and inductance value at higher temperatures to ensure reliable operation.
• Can I use the SPM3015T-4R7M inductor in a high-frequency application?
  The SPM3015T-4R7M inductor is designed for high-frequency applications up to 100 MHz. However, it's essential to consider the component's self-resonant frequency (SRF) and quality factor (Q) when designing the circuit to ensure optimal performance.
• How do I ensure the SPM3015T-4R7M inductor is properly soldered to the PCB?
  To ensure proper soldering, it's recommended to use a soldering iron with a temperature range of 250°C to 260°C, and to apply a small amount of solder paste to the pads. The component should be placed on the PCB with the leads aligned to the pads, and then soldered using a gentle touch to avoid applying excessive force.
