153H

Overview

The Hammond Manufacturing 153H is a leaded power inductor designed as a DC reactor and filter choke. It features an unshielded construction with wire leads for chassis mounting via an open channel bracket. The component provides an inductance of 2.2 H with a tolerance of 15%. It supports a maximum DC current of 50 mA and has a maximum DC resistance of 305 ohms. The unit is rated for a maximum voltage of 300 VDC. Physical dimensions are approximately 41.4 mm in length, 22.4 mm in width, and 20.6 mm in height, weighing 0.3 lbs.

Feature Summary

• Economical open bracket channel mount design for straightforward installation
• Unshielded core construction suitable for general filtering applications
• Inductance values measured at rated DC current to ensure performance accuracy

Applications

• DC reactor circuits requiring stable inductance under load
• Filter choke applications in low-current power supplies
• Chassis-mounted electronic equipment needing economical inductive components

Procurement Notes

Verify the specific inductance value of 2.2 H and current rating of 50 mA against circuit requirements before ordering. Confirm that the 305-ohm DC resistance is acceptable for the target application's voltage drop constraints. Ensure the chassis mounting style aligns with the mechanical layout of the final assembly. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a high-inductance, low-current filter choke is needed for chassis mounting. The open channel design simplifies mechanical integration compared to enclosed packages. Consider the significant DC resistance when calculating power loss and thermal management. This part is suitable for applications where shielding is not critical and cost-effectiveness is a priority over compact size.

Part Context

The 153H belongs to the Hammond Manufacturing 153-159 series of fixed inductors. This series includes various models with different inductance and current ratings, such as the 1530B153 and 154E. These components share similar physical mounting characteristics and construction styles, offering a range of options for DC reactor and filter choke needs within the same product family.

Replacement Considerations

Direct substitutes within the same series include the 1530B153. When replacing, verify that the alternative part matches the 2.2 H inductance and 50 mA current rating. Ensure the replacement maintains the same chassis mounting footprint and wire lead configuration to fit existing hardware without modification.
