PM1608-331M

Fixed Inductors Overview

The PM1608-331M is a fixed wirewound inductor from Bourns Inc., featuring an unshielded drum core. It offers a nominal inductance of 330 µH with a tolerance of ±20%. The component supports a maximum DC current of 160 mA and exhibits a maximum DC resistance of 3.8 Ohms. Designed for surface mount applications, it provides a compact footprint suitable for space-constrained circuit layouts.

Fixed Inductors Feature Summary

• Unshielded drum core construction
• Wirewound technology
• Low profile miniature size
• High heat resistance ideal for reflow processes

Fixed Inductors Applications

• General purpose power supply filtering
• Signal processing circuits
• Consumer electronics power management

Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure compliance with RoHS directives and lead-free requirements. Confirm that the package dimensions align with the target PCB land pattern. Check for any automotive or industrial qualification certifications if the application demands high reliability standards beyond standard commercial grades.

Fixed Inductors Selection Notes

Select this component when a non-shielded inductor is acceptable to minimize cost and height. Ensure the operating current does not exceed the 160 mA rating to prevent saturation. Consider thermal dissipation capabilities during reflow soldering due to the high heat resistance feature. Validate impedance characteristics against the specific frequency requirements of the target circuit design.

Fixed Inductors Part Context

This part belongs to the PM1608 series of SMD power inductors manufactured by Bourns Inc. The series includes various inductance values within the same physical envelope. It represents a standard solution for general-purpose magnetic components where shielding is not strictly required for EMI suppression.

Fixed Inductors Replacement Considerations

Cross-reference with other manufacturers offering 330 µH unshielded drum core inductors in similar footprints. Verify that substitute parts meet the same 160 mA current and 3.8 Ohm resistance specifications to maintain circuit performance integrity.
