RL-1256-6-120

Fixed Inductors Overview

The RL-1256-6-120 is a fixed power line choke manufactured by Renco Electronics, Inc. It features an unshielded wirewound design with a radial vertical cylinder package for through-hole mounting. The component provides an inductance of 120 µH and supports a maximum current rating of 27 A. Its direct current resistance is specified as a maximum of 15 mΩ. The physical dimensions include a diameter of 2.000 inches (50.80 mm) and a seated height of up to 1.500 inches (38.10 mm).

Fixed Inductors Feature Summary

• Unshielded wirewound construction designed for high saturation flux applications.
• Radial vertical cylinder package suitable for through-hole mounting.
• High current handling capability of 27 A with low DC resistance.

Fixed Inductors Applications

• Power line filtering in industrial equipment.
• Choke applications requiring high saturation flux.
• Through-hole mounted power supply circuits.

Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct inductance value and tolerance are selected. Confirm that the radial through-hole mounting style aligns with the target PCB layout requirements. Check the maximum seated height constraint to ensure adequate clearance within the final assembly enclosure. Cross-reference the 27 A current rating with the thermal management plan of the end application.

Fixed Inductors Selection Notes

Select this component when a high-current, unshielded power line choke is required for through-hole assembly. The 120 µH inductance and 27 A rating suit heavy-duty power filtering tasks. Ensure the 2.000-inch diameter fits the available board space. Consider the lack of shielding if electromagnetic interference isolation is critical for nearby sensitive components.
