DR127-102-R Frequently Asked Questions (FAQ)
-
The recommended land pattern for the DR127-102-R is a rectangular pad with a size of 3.8mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape. This can be found in the Coiltronics application note AN-001.
-
The DR127-102-R has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management in your design. This can include using thermal vias, heat sinks, or other cooling mechanisms to keep the inductor within its specified temperature range.
-
The SRF of the DR127-102-R is not explicitly stated in the datasheet. However, according to Coiltronics' application note AN-002, the SRF can be estimated using the following formula: SRF (MHz) = 159 / (L1 * C1)^0.5, where L1 is the inductance value and C1 is the equivalent series capacitance. For the DR127-102-R, the estimated SRF is around 35 MHz.
-
While the DR127-102-R is suitable for high-frequency applications, its performance may degrade above 10 MHz due to the inductor's equivalent series resistance (ESR) and equivalent series inductance (ESL). It's essential to evaluate the inductor's performance in your specific application and consider other inductor options if necessary.
-
To ensure the DR127-102-R meets your specific impedance requirements, you can use impedance modeling tools or consult with Coiltronics' application engineers. They can provide guidance on selecting the appropriate inductor value and optimizing your design for the desired impedance characteristics.
