The recommended land pattern for WB36-1L is a rectangular pad with a size of 3.8 mm x 2.5 mm, with a non-solder mask defined (NSMD) pad shape. This ensures proper soldering and minimizes the risk of solder bridging.
WB36-1L is rated for operation up to 125°C, but it's essential to derate the current rating according to the temperature derating curve provided in the datasheet. Above 125°C, the inductor's performance and reliability may be compromised.
To minimize the impact of mechanical stress, ensure that the inductor is handled carefully during assembly and installation. Avoid bending, flexing, or applying excessive force to the component. If the inductor is subjected to mechanical stress, it's crucial to follow the recommended reflow soldering profile to minimize the risk of damage.
The ESR of WB36-1L is not explicitly stated in the datasheet, but it can be estimated based on the inductor's DC resistance (Rdc) and the frequency of operation. As a rough estimate, the ESR is typically around 10-20% of the Rdc value at high frequencies (e.g., 100 kHz to 1 MHz).
While WB36-1L is designed to be robust, it's still important to consider the vibration environment in which it will operate. Coilcraft recommends following the IPC-J-STD-001 standard for vibration testing. If the inductor will be subjected to extreme vibration, it's essential to perform additional testing and analysis to ensure its reliability.
