DR127-331-R Frequently Asked Questions (FAQ)
-
The recommended PCB land pattern for the DR127-331-R is a rectangular pad with a minimum size of 3.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape.
-
The DR127-331-R has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a thermal interface material (TIM) to improve heat transfer between the inductor and the PCB.
-
The SRF of the DR127-331-R is not explicitly stated in the datasheet, but it can be estimated to be around 100-150 MHz based on the inductor's physical characteristics and similar products from Coiltronics.
-
While the DR127-331-R is a robust component, it's essential to ensure the inductor is properly secured to the PCB using a suitable adhesive or mechanical fastening method to withstand vibrations. Consult Coiltronics' application notes for more information.
-
The saturation current of the DR127-331-R can be estimated using the inductor's DC resistance (DCR) and the core material's saturation characteristics. Consult Coiltronics' application notes or contact their technical support for guidance.
