2890R-03K Frequently Asked Questions (FAQ)
-
The recommended land pattern for the 2890R-03K can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and land pattern design.
-
To minimize the risk of moisture-related damage, store the 2890R-03K in a dry, cool place, and follow the recommended soldering and handling procedures. API Delevan also recommends baking the components at 125°C for 24 hours before soldering to remove any moisture that may have been absorbed during storage.
-
While the datasheet specifies a maximum DC resistance, it does not explicitly state a maximum allowable voltage. However, as a general guideline, it's recommended to limit the voltage across the inductor to 1.5 times the rated current multiplied by the DC resistance to avoid overheating and ensure reliable operation.
-
The 2890R-03K is rated for operation up to 125°C, but its performance and reliability may degrade at higher temperatures. If your application requires operation above 125°C, consider using a higher-temperature-rated inductor or consulting with API Delevan's application engineers for guidance.
-
The self-resonant frequency of the 2890R-03K can be determined by measuring the impedance vs. frequency characteristic using a network analyzer or impedance analyzer. The self-resonant frequency is typically the frequency at which the impedance peaks.
