LQG15HSR12H02D - Murata Electronics

LQG15HSR12H02D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQG15HSR12H02D?
  The recommended land pattern for LQG15HSR12H02D is a rectangular pad with a size of 1.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a solder mask opening of 1.2 mm x 1.2 mm.
• Can I use the LQG15HSR12H02D in a high-temperature environment?
  The LQG15HSR12H02D is rated for operation up to 125°C, but it's recommended to derate the current rating according to the temperature derating curve provided in the datasheet. Above 125°C, the inductor's performance and reliability may be compromised.
• How do I handle the LQG15HSR12H02D during PCB assembly to prevent damage?
  Handle the LQG15HSR12H02D by the edges or the tape, avoiding touching the component body or the terminals. Use a vacuum pick-up tool or a tweezers with a soft grip to prevent scratching or bending the leads. Avoid exposing the component to excessive mechanical stress, moisture, or electrostatic discharge.
• What is the equivalent series resistance (ESR) of the LQG15HSR12H02D?
  The ESR of the LQG15HSR12H02D is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on the inductor's design and materials. However, for accurate ESR values, it's recommended to consult with Murata's application engineers or perform measurements in your specific application.
• Can I use the LQG15HSR12H02D in a DC-DC converter design?
  Yes, the LQG15HSR12H02D is suitable for use in DC-DC converter designs, particularly in high-frequency switching applications. However, ensure that the inductor is properly selected based on the converter's operating frequency, current rating, and other design parameters to avoid saturation and ensure efficient operation.
