Procurement Notes
Verify the specific inductance value of 27 mH at 10 kHz and the 800 mA current rating against the official datasheet before integration. Confirm that the through-hole package dimensions align with the PCB footprint requirements. Ensure compliance with RoHS3 regulations if required by the end product specifications. Cross-reference the manufacturer part number CAV-0.8-27 to avoid confusion with similar series components.
Selection Notes
Select this component when high inductance is required for low-frequency common mode noise reduction. The 800 mA current rating suits moderate power applications. Consider the physical height constraint of 20.00 mm for enclosure clearance. The wide temperature range allows use in industrial or automotive contexts where thermal stability is critical. Verify compatibility with automated assembly processes due to the through-hole format.
Part Context
