The recommended land pattern for the 2929SQ-361JEC is a rectangular pad with a size of 2.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad shape. This can be found in Coilcraft's application notes or by contacting their technical support.
The 2929SQ-361JEC has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management in your design. This includes providing adequate airflow, using thermal vias, and keeping the inductor away from heat sources. Coilcraft provides thermal derating charts in their datasheet to help with this.
The self-resonant frequency (SRF) of the 2929SQ-361JEC is not explicitly stated in the datasheet. However, Coilcraft provides an impedance vs. frequency graph that can be used to estimate the SRF. Typically, the SRF is around 100-150 MHz for this inductor, but it's recommended to consult with Coilcraft's technical support for a more accurate value.
The 2929SQ-361JEC is a surface-mount inductor, and its mechanical robustness is suitable for most applications. However, if your design will be exposed to high vibrations (e.g., in automotive or industrial environments), it's recommended to consult with Coilcraft's technical support to discuss the inductor's mechanical stress limits and potential derating.
To ensure the reliability of the 2929SQ-361JEC in a high-reliability application, follow proper storage and handling procedures, and ensure that the inductor is soldered correctly. Additionally, consider using Coilcraft's high-reliability versions of the inductor, which may have additional screening and testing. Consult with Coilcraft's technical support for more information.
