Overview
The Hammond Manufacturing 157L is a DC reactor and filter choke designed for open channel mounting. It features an unshielded inductance of 14 H with a maximum DC current rating of 75 mA. The component utilizes a nonstandard resistance value of 429 Ohms. This industrial-grade inductor is constructed for reliable performance in signal filtering and power conditioning applications requiring high inductance at low current levels.
Feature Summary
- Provides high inductance for effective DC filtering and signal noise reduction
- Designed for open channel mounting to facilitate integration into existing chassis or rack systems
- Unshielded construction allows for flexible placement within equipment layouts
Applications
- DC power supply input filtering
- Signal processing circuit noise suppression
- Industrial control system power conditioning
Procurement Notes
Verify the specific inductance tolerance and DC resistance values against the official Hammond Manufacturing datasheet prior to procurement. Confirm that the 75 mA current rating aligns with the target application's operational requirements. Ensure the open channel mounting style is compatible with the intended mechanical assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when a high inductance value of 14 H is required for low-current DC applications. The 75 mA rating dictates suitability for small-signal or control power circuits rather than high-power loads. Consider the unshielded design if magnetic interference with adjacent components is not a primary constraint. Evaluate the physical dimensions and mounting hole spacing to ensure fit within the designated enclosure space.
Part Context
The 157L belongs to Hammond Manufacturing's line of fixed inductors, specifically categorized as leaded DC reactors. These components are engineered for robust industrial environments where stable inductance characteristics are critical. The product supports applications demanding precise current smoothing and harmonic attenuation in direct current circuits.
Replacement Considerations
Consult the official Hammond Manufacturing documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' inductors without verifying electrical parameters and mechanical dimensions.
