WCLA1005V1-820-R

Fixed Inductors Overview

The WCLA1005V1-820-R is a surface-mount inductor from Eaton's WCLA series, designed for high-frequency applications. It features an 82 µH nominal inductance with a tolerance of ±10%. The component operates at a self-resonant frequency of 4.5 MHz and has a DC resistance of 3.5 Ω maximum. Rated for a saturation current of 10 mA and a thermal current of 10 mA, it utilizes a shielded magnetic core construction within a compact 0402 (1005 metric) package.

Fixed Inductors Feature Summary

• Shielded magnetic core construction minimizes electromagnetic interference to adjacent circuit components.
• Compact 0402 footprint enables dense PCB layout for space-constrained portable electronics.
• High self-resonant frequency supports stable performance in RF and signal processing circuits.

Fixed Inductors Applications

• RF filtering in wireless communication modules
• Signal conditioning in mobile device power management systems
• EMI suppression in compact consumer electronics

Fixed Inductors Procurement Notes

Verify the specific suffix 'R' indicates the standard reel packaging configuration as per Eaton's official documentation. Confirm that the voltage rating and current limits align with your system's operational requirements before finalizing procurement. Ensure the supplier provides traceable datasheets matching the exact part number to avoid counterfeit or mismatched components.

Fixed Inductors Selection Notes

Select this component when space constraints require a 0402 package size while maintaining shielding against EMI. The low current ratings necessitate careful evaluation of the application's power budget. Engineers should prioritize this part for signal integrity applications rather than high-power energy storage roles due to its saturation characteristics.

Fixed Inductors Part Context

This part belongs to Eaton's WCLA series of shielded wire-wound inductors. These components are engineered for high reliability in demanding electronic environments. The series offers various inductance values within the same form factor, allowing designers to customize circuit parameters without altering the physical board layout constraints.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 0402 footprint, 82 µH inductance, and similar current ratings. Cross-reference with other manufacturers' shielded inductors in the SMD-0402 category, ensuring equivalent DCR and SRF specifications are met to maintain circuit performance.
