The recommended land pattern for the DR125-4R7-R is a rectangular pad with a size of 3.8mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape. This ensures proper soldering and minimizes the risk of solder bridging.
The DR125-4R7-R 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. Consult the datasheet and Coiltronics' application notes for more information.
Handle the DR125-4R7-R by the body, avoiding touching the leads or the core. Use a vacuum pickup or tweezers to place the component on the PCB. Avoid bending or flexing the leads, and ensure the component is properly seated on the PCB before soldering.
The ESR of the DR125-4R7-R is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on the inductor's design and materials. Consult Coiltronics' application notes or contact their technical support for more information.
The DR125-4R7-R is designed for general-purpose use and may not be suitable for high-frequency applications above 1 MHz. The inductor's self-resonant frequency (SRF) is not specified in the datasheet, but it's typically in the range of 10-50 MHz for similar inductors. Consult Coiltronics' application notes or contact their technical support for more information.
