Procurement Notes

Verify the specific datasheet version for the 744834220 part number to confirm mechanical drawings and electrical tolerances. Ensure the procurement channel provides original manufacturer documentation. Cross-reference the 20 mH inductance and 2 A current rating against system requirements before ordering. Confirm through-hole package compatibility with assembly processes.

Selection Notes

Select this component when horizontal mounting space allows for a 32.5 x 28 mm footprint. The 230 mOhm DCR suits applications requiring low insertion loss at 2 A. Consider the 20 mH value for standard line-frequency noise attenuation. Verify that the operating temperature range meets environmental conditions.
