Applications
- Power supply input filtering
- EMI suppression in electronic equipment
- Signal integrity protection in data lines
Procurement Notes
Verify the specific ordering suffix and packaging quantity required by your supplier, as bulk quantities may vary between distributors. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement. Ensure the lead time aligns with production schedules, as availability may fluctuate. Cross-reference the datasheet revision date to ensure compatibility with current design standards.
Selection Notes
Select this component when a robust, high-current common mode choke is required for horizontal PCB mounting. The 2.2 A rating makes it suitable for applications with significant DC bias. Verify that the physical footprint fits the board layout constraints. Consider the unshielded nature if magnetic interference with nearby components is a concern. Ensure the operating temperature range meets the environmental requirements of the end application.
Part Context
The CM1011R-335 belongs to the CM1011R series of common mode chokes manufactured by API Delevan. This series is characterized by its horizontal mounting style and epoxy potting, which provides durability against vibration and moisture. The part is designed for general-purpose EMI suppression in various electronic systems.
Replacement Considerations
Direct substitutes must match the 3.3 mH inductance, 2.2 A current rating, and horizontal through-hole package. Verify pinout compatibility and physical dimensions to ensure fitment on existing PCBs. Check if alternative parts offer similar DC resistance and temperature ratings.
