Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact tolerance and current ratings. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Cross-reference the part number with the latest datasheet revisions to confirm compliance with required environmental standards and RoHS directives before finalizing orders.

Selection Notes

Select this component when high inductance values are required in a compact axial form factor. The unshielded construction necessitates careful PCB layout to minimize electromagnetic interference coupling with adjacent traces. Evaluate the 33 mA current limit against peak load requirements to prevent saturation. Consider the 1.7 MHz self-resonant frequency to ensure operation remains within the intended inductive range for the target application frequency.
