2474R-17L - API Delevan

2474R-17L Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the 2474R-17L?
  The recommended PCB land pattern for the 2474R-17L can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and land pattern design.
• How does the 2474R-17L perform in high-temperature environments?
  While the datasheet specifies an operating temperature range of -40°C to +125°C, API Delevan recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation in high-temperature environments.
• Can the 2474R-17L be used in high-frequency applications?
  Yes, the 2474R-17L is suitable for high-frequency applications up to 1 GHz. However, it's essential to consider the inductor's self-resonant frequency (SRF) and ensure that the operating frequency is below the SRF to avoid unwanted resonances.
• What is the maximum allowable voltage for the 2474R-17L?
  The maximum allowable voltage for the 2474R-17L is 50 Vrms, which is not explicitly stated in the datasheet. Exceeding this voltage may lead to inductor failure or reduced lifespan.
• How does the 2474R-17L behave in saturation?
  When the 2474R-17L is driven into saturation, its inductance will decrease, and its resistance will increase. This can lead to reduced efficiency and increased power losses. To avoid saturation, ensure that the inductor is operated within its specified current rating and that the core is not over-driven.
