157J

Overview

The Hammond Manufacturing 157J is a fixed DC reactor and filter choke designed for low to medium current applications. It features an unshielded construction with open channel mounting capabilities. The component provides an inductance of 10 H and supports a maximum DC current of 65 mA. It exhibits a resistance of 205 Ohms and utilizes a nonstandard physical form factor suitable for industrial automation environments.

Feature Summary

• Provides stable filtering for direct current circuits using high-inductance coil technology
• Features an open channel design that facilitates secure mechanical mounting on standard rails or panels
• Constructed as an unshielded unit to minimize weight while maintaining electrical performance

Applications

• DC link filtering in industrial automation systems
• Power supply output smoothing for low-current electronic loads
• Signal conditioning within PLC input/output stages

Procurement Notes

Verify the specific inductance value of 10 H and current rating of 65 mA against circuit requirements before ordering. Confirm the nonstandard package dimensions fit the intended open channel mounting space. Ensure the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field exposure.

Selection Notes

Select this component when a robust, leaded DC reactor is required for industrial-grade reliability. The open channel mount offers flexibility compared to surface-mount alternatives. Consider the 205 Ohm resistance impact on voltage drop within the specific low-current application context.
