300HS-181J=P2

Overview

The 300HS-181J=P2 is a fixed inductor manufactured by Toko America Inc., designed for surface-mount applications. It features an unshielded drum core construction with wirewound technology, housed in a standard 1812 (4532 Metric) package. The component provides an inductance value of 180 µH with a tolerance of ±5%. It supports a maximum DC current of 60 mA and exhibits a maximum DC resistance of 5.58 Ohms. Electrical characterization is typically performed at a frequency of 796 kHz with a test signal of 50 mA.

Feature Summary

• Unshielded drum core design for compact surface-mount integration
• Wirewound construction ensuring stable inductance characteristics
• Standardized 1812 footprint for automated assembly compatibility

Applications

• General-purpose signal filtering in electronic circuits
• Power supply input/output stages requiring moderate inductance
• EMI suppression in consumer electronics assemblies

Procurement Notes

Verify the complete part number including the suffix =P2 to ensure correct packaging configuration. Confirm that the specified 60 mA current rating aligns with the target circuit's operational requirements. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure storage conditions maintain component integrity prior to soldering.

Selection Notes

Select this component when a 180 µH inductance value is required within a 1812 package constraint. Consider the 60 mA current limit to prevent saturation in the intended application. Evaluate the 5.58 Ohm DC resistance against power loss tolerances. Compare performance against shielded alternatives if magnetic interference sensitivity is a critical design factor.
