The recommended PCB land pattern for the DR1040-680-R can be found in the Coiltronics application note AN-013, which provides detailed guidelines for PCB layout and footprint design.
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 DR1040-680-R is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in high-vibration applications such as automotive and industrial systems.
The SRF of the DR1040-680-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 simulation and modeling tools.
Yes, the DR1040-680-R is compatible with lead-free soldering processes, including RoHS and WEEE compliant soldering profiles.
