DR1040-7R0-R Details

The recommended PCB land pattern for the DR1040-7R0-R can be found in the Coiltronics application note AN-001, which provides detailed guidelines for PCB layout and assembly.
While the datasheet specifies an operating temperature range of -40°C to +125°C, Coiltronics recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation in high-temperature environments.
Yes, the DR1040-7R0-R is compatible with lead-free soldering processes, and Coiltronics recommends using a peak reflow temperature of 260°C to ensure reliable assembly.
The SRF of the DR1040-7R0-R is approximately 150 MHz, which is not explicitly stated in the datasheet. This information can be obtained by contacting Coiltronics' technical support or through additional characterization.
While the DR1040-7R0-R is designed to be rugged, Coiltronics recommends additional testing and validation to ensure the inductor's performance and reliability in high-vibration or high-shock environments.
