157Q

Overview

The Hammond Manufacturing 157Q is a fixed power inductor designed for industrial applications. It features an unshielded construction with a nominal inductance of 3.5 H and a maximum DC current rating of 150 mA. The component exhibits a DC resistance of 98 Ohms and utilizes wire leads for termination. It supports chassis mounting and operates within a temperature range of 0°C to +105°C at 50/60 Hz frequencies.

Feature Summary

• Unshielded core design suitable for general-purpose filtering
• Chassis mount configuration for secure installation
• Wire lead termination for flexible circuit integration

Applications

• DC reactor circuits
• Filter choke applications
• Industrial control transformer support

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and physical dimensions prior to integration. Ensure that the operating environment remains within the specified thermal limits. Confirm that the wire lead gauge meets the mechanical stress requirements of the final assembly layout.

Selection Notes

Select this component when a high-inductance, low-current filter is required for DC lines. The unshielded nature necessitates careful placement to avoid magnetic interference with adjacent sensitive components. Verify that the chassis mounting holes align with the enclosure design specifications.

Part Context

This part belongs to the Hammond 157 series of fixed inductors. It shares similar mounting characteristics with other models in the series but differs in inductance and current ratings. It serves as a specialized passive component for power conditioning within larger industrial systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching inductance, current, and resistance values from alternative manufacturers.
