Coilcraft provides a recommended land pattern for the SER2011-202MLB in their documentation, which can be found on their website. The recommended land pattern is designed to ensure optimal performance and reliability of the inductor.
The SER2011-202MLB is rated for operation up to 125°C, but it's recommended to derate the current rating at higher temperatures. Coilcraft provides a temperature derating curve in their documentation, which can be used to determine the maximum current rating at a given temperature.
To prevent damage during PCB assembly, it's recommended to handle the SER2011-202MLB by the body, avoiding touching the leads or core. It's also recommended to use a vacuum pickup or tweezers to handle the component, and to avoid bending or flexing the leads.
The SER2011-202MLB is designed to withstand moderate vibration, but it's recommended to consult with Coilcraft or perform additional testing to ensure the component can withstand the specific vibration requirements of your application.
The ESR of the SER2011-202MLB can be determined by measuring the impedance of the inductor at high frequency (e.g. 100 kHz) and calculating the ESR using the measured impedance and inductance values. Coilcraft also provides ESR data in their documentation for reference.
