MWSD1005C1N3DTM81

Fixed Inductors Overview

The MWSD1005C1N3DTM81 is a fixed surface-mount inductor manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a drum core, wirewound construction with a ceramic magnetic core and no shielding. The component has an inductance of 1.3 nH with a tolerance of ±0.5 nH. It supports a maximum rated current of 3.15 A and exhibits a maximum DC resistance (DCR) of 12 mΩ. Designed for the 0402 (1005 metric) package, it measures 1.10 mm in length, 0.53 mm in width, and 0.70 mm in height. The device operates within a temperature range of -40°C to +125°C.

Fixed Inductors Feature Summary

• Drum core wirewound architecture for high-frequency performance
• Compact 0402 surface-mount footprint for space-constrained designs
• High current handling capability suitable for power delivery paths

Fixed Inductors Applications

• RF signal coupling and matching networks
• Power supply output filtering
• High-speed digital line termination

Fixed Inductors Procurement Notes

Verify the specific ordering suffix TM81 against the manufacturer's official datasheet to ensure correct packaging and reel specifications. Confirm that the 0402 package dimensions align with your PCB land pattern requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure storage conditions adhere to moisture sensitivity level guidelines upon receipt.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values are required for RF applications or impedance matching. The 1.3 nH value and 3.15 A rating make it suitable for high-current, high-frequency circuits. Consider the 0402 size constraint and verify that the self-resonant frequency characteristics meet your circuit's operational bandwidth needs compared to larger package alternatives.

Fixed Inductors Part Context

This part belongs to the MWSD-C-M series of multi-layer chip ceramic inductors from Sunlord. These components are designed for high-frequency applications requiring stable inductance values in small form factors. The series utilizes advanced ceramic materials and wirewound techniques to achieve low DCR and high Q factors, supporting modern electronics' trend toward miniaturization and higher performance.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0402 wirewound inductors with similar 1.3 nH inductance and ≥3.15 A current ratings. Verify that alternative parts match the 12 mΩ DCR limit and physical dimensions. Cross-reference with Sunlord's internal cross-reference guides for exact pin-compatible replacements within the same product family.
