154H

Overview

The Hammond Manufacturing 154H is a fixed inductor designed for DC filter applications. It features an unshielded construction with leaded termination, suitable for through-hole mounting. The component provides 4 H of inductance and has a maximum DC resistance of 300 Ohms. It supports a current rating of 50 mA. The device operates without shielding to minimize interference in specific circuit layouts.

Feature Summary

• Unshielded design for targeted electromagnetic compatibility
• Leaded termination for standard PCB integration
• Fixed inductance value for stable filtering performance

Applications

• DC power supply filtering
• Choke applications in low-current circuits
• Signal conditioning in industrial control systems

Procurement Notes

Verify the exact inductance tolerance and temperature coefficient against the manufacturer's datasheet before procurement. Confirm that the 50 mA current rating aligns with the peak load requirements of the target circuit. Ensure the unshielded nature does not conflict with nearby sensitive components. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a high-impedance choke is required for low-current DC lines. The 300 Ohm resistance limits its use to applications where voltage drop is acceptable. Consider the physical size and lead spacing for PCB layout constraints. Compare with shielded alternatives if EMI suppression is critical for adjacent signals.

Part Context

This inductor belongs to Hammond Manufacturing's range of passive components for industrial electronics. It complements their enclosure and hardware products by providing essential circuit protection elements. The 154H model serves as a specialized filter within broader power management designs, often paired with capacitors for smoothing.

Replacement Considerations
