156R

Overview

The Hammond Manufacturing 156R is a leaded DC reactor and filter choke designed for open channel mounting. It features an unshielded construction with an inductance of 1.5 H and a maximum DC current rating of 200 mA. The component has a tolerance of 15% and a maximum DC resistance of 56 ohms. Its physical dimensions are 71.374 mm in length, 38.1 mm in width, and 42.926 mm in height.

Feature Summary

• Open channel mount design for chassis installation
• Unshielded core construction
• Lead wire termination style

Applications

• DC power supply filtering
• Current limiting in low to medium current circuits
• Choke applications in industrial control systems

Procurement Notes

Verify the specific datasheet version to confirm electrical parameters such as inductance and current ratings, as these can vary by revision. Ensure the mounting configuration matches the open channel requirement. Check RoHS compliance status if environmental regulations apply to the end product. Confirm that the lead wire gauge and length meet the assembly requirements.

Selection Notes

Select this component when a fixed inductance of 1.5 H is required for DC line filtering or current smoothing. The 200 mA current rating limits its use to low-power applications. Consider the unshielded nature for potential EMI management in the final enclosure design. Compare against other series members like the 156B if higher current capacity is needed.

Part Context

This part belongs to the Hammond Manufacturing series of DC reactors and filter chokes intended for low to medium current applications. These components are typically used in power conversion and distribution systems where stable DC output is critical. The series offers various inductance values and current ratings to suit different circuit demands.

Replacement Considerations

The Hammond Manufacturing 156B is a confirmed substitute within the same product family, offering similar functionality but with different electrical specifications.
