SRN2009T-2R2M

Fixed Inductors Overview

The SRN2009T-2R2M is a fixed inductor from Bourns Inc., belonging to the SRN2009T series of semishielded power inductors. It features a wirewound construction with a drum core and is housed in an 0806 (2016 Metric) surface-mount package. The component provides an inductance value of 2.2 µH with a tolerance of ±20%. It supports a maximum DC current of 900 mA, which also serves as the saturation current rating. The maximum DC resistance is specified at 160 mOhms. The device is designed for operation within a minimum temperature range of -40°C.

Fixed Inductors Feature Summary

• Semishielded wirewound design utilizing a drum core structure
• Compact 0806 surface-mount footprint suitable for space-constrained layouts
• Halogen-free composition meeting environmental standards

Fixed Inductors Applications

Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct tolerance and packaging configuration. Confirm that the required current ratings align with the system's operational demands. Check for any updated environmental compliance declarations or RoHS status changes directly from the supplier before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact semishielded inductor is required for low-current applications. The 900 mA rating defines the operational limit for both DC bias and saturation. Ensure the PCB layout accommodates the 0806 dimensions. Consider the 160 mOhm resistance impact on overall circuit efficiency during thermal analysis.

Fixed Inductors Part Context

This part belongs to the SRN2009T series, which comprises semishielded power inductors manufactured by Bourns Inc. The series is categorized under SMD Power Inductors and is engineered for applications where moderate shielding is sufficient to reduce electromagnetic interference while maintaining a low profile.

Fixed Inductors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 2.2 µH inductance, 900 mA current rating, and 0806 footprint without altering board compatibility.
