2522195518G4 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the 2522195518G4 inductor is a rectangular pad with a size of 3.8mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a clearance of at least 0.5mm from the edge of the board.
• Can I use this inductor in a high-temperature environment?
  The 2522195518G4 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. It's also important to consider the temperature coefficient of inductance, which is -20 ppm/°C, when designing for high-temperature applications.
• How do I handle the inductor's magnetic field in my design?
  The 2522195518G4 inductor has a magnetic field that can interact with nearby components. To minimize this effect, it's recommended to keep the inductor at least 5mm away from sensitive components, such as oscillators or magnetically sensitive devices. You can also use shielding or mu-metal to contain the magnetic field.
• What is the inductor's self-resonant frequency?
  The self-resonant frequency of the 2522195518G4 inductor is not specified in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Typically, the self-resonant frequency is around 100-200 MHz for this type of inductor. However, it's recommended to consult with Fair-Rite Products Corp or perform your own measurements to determine the exact self-resonant frequency.
• Can I use this inductor in a high-current application?
  The 2522195518G4 inductor has a maximum current rating of 1.8 A, but it's recommended to derate the current rating based on the operating temperature and frequency. It's also important to consider the inductor's power handling capability, which is 1.3 W, and ensure that the design does not exceed this rating.
