The Hammond Manufacturing 159ZA is a leaded power inductor designed as a DC reactor and filter choke. It features an open channel mount configuration suitable for chassis installation. The component provides an inductance of 300 mH with a tolerance of 15%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 6 ohms. The unit is unshielded and utilizes wire leads for termination. Physical dimensions include a length of 102.362 mm, width of 57.15 mm, and height of 66.802 mm.
Verify the exact inductance value of 300 mH and the 1 A current rating against your circuit requirements before ordering. Confirm that the unshielded design does not interfere with nearby sensitive components due to potential magnetic field exposure. Ensure the chassis mounting style aligns with your mechanical assembly constraints. Check that the wire lead type matches your PCB or terminal block interface needs.
Select this component when a fixed 300 mH inductance is required for DC line filtering. Consider the physical size of over 10 cm in length during layout planning. The 6 ohm DC resistance will impact voltage drop; calculate power dissipation at the operating current. This part is suitable for general industrial environments but lacks shielding, so placement relative to other magnetic sources is critical.
This component belongs to the Hammond Manufacturing power inductor series, specifically categorized as a leaded DC reactor. It is distinct from surface-mount inductors and toroidal chokes, offering a robust solution for through-hole or direct wiring applications in industrial control panels and power distribution units.
