API Delevan provides a recommended PCB land pattern in their application notes, which can be found on their website. The recommended land pattern is designed to ensure optimal performance and reliability of the inductor.
The 1641R-124K is rated for operation up to 125°C, but derating is required for temperatures above 85°C. Consult the datasheet for specific derating guidelines. Additionally, it's essential to consider the temperature coefficient of inductance and resistance when operating in high-temperature environments.
The 1641R-124K is a shielded inductor, and proper magnetic shielding is crucial to minimize electromagnetic interference (EMI). API Delevan recommends using a mu-metal shield or a similar material to enclose the inductor. The shield should be grounded to the PCB to ensure effective shielding.
The self-resonant frequency (SRF) of the 1641R-124K is not explicitly stated in the datasheet. However, API Delevan provides SRF data for similar inductors in their application notes. As a general guideline, the SRF of the 1641R-124K is likely to be in the range of 50-100 MHz. For specific SRF data, contact API Delevan's technical support.
The 1641R-124K is rated for a maximum current of 1.24 A. While it can handle high-current applications, it's essential to consider the inductor's temperature rise, power loss, and saturation characteristics. Consult the datasheet and API Delevan's application notes for guidance on high-current applications.
