The recommended PCB land pattern for the S4924-105K can be found in the API Delevan application note AN-113, which provides detailed guidelines for PCB layout and footprint design.
While the datasheet specifies an operating temperature range of -40°C to +125°C, API Delevan recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation in high-temperature environments.
The SRF of the S4924-105K is typically around 150 MHz, but this value can vary depending on the specific application and PCB layout. It's essential to consider the SRF when designing the circuit to avoid unwanted resonances.
Yes, the S4924-105K is designed to meet the requirements of high-reliability and military applications. API Delevan offers a range of screening options, including MIL-PRF-83446 and MIL-PRF-39007, to ensure the inductor meets the necessary standards.
When the S4924-105K is driven into saturation, its inductance will decrease, and its DC resistance will increase. It's essential to consider the saturation characteristics when designing the circuit to avoid unwanted behavior and ensure reliable operation.
