WBC1-1LC

Overview

The Coilcraft WBC1-1LC is a surface-mount mini wideband transformer designed for RF signal applications. It features a 1:1 turns ratio and operates within a frequency range of 400 kHz to 600 MHz. The component utilizes a ferrite core material and provides an inductance of 10 uH with a maximum DC resistance of 120 mOhms. It is housed in a compact SMD package measuring 4.45 mm in length, 4.19 mm in width, and 3.04 mm in height. The device supports a minimum operating temperature of -40°C and a maximum of +85°C, ensuring reliability across standard industrial temperature ranges.

Feature Summary

• Miniature surface-mount construction optimized for space-constrained PCB layouts
• Wideband operational capability spanning from low-frequency signals up to 600 MHz
• Ferrite core design providing stable impedance transformation characteristics

Applications

• RF signal coupling and isolation in communication circuits
• Impedance matching networks for high-frequency signal paths
• Balun applications requiring 1:1 transformation ratios

Procurement Notes

Verify the specific manufacturer part number against official Coilcraft documentation to ensure compatibility with design requirements. Confirm that the surface-mount footprint dimensions align with the target PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure that the operating temperature range meets the thermal conditions of the intended application environment.

Selection Notes

Select this component when a 1:1 wideband transformer is required for frequencies between 400 kHz and 600 MHz. Consider the 10 uH inductance value for circuit tuning needs. Evaluate the 120 mOhms DC resistance against power loss constraints. Verify that the 4.45 mm x 4.19 mm package fits within the available board space. Assess thermal performance against the specified -40°C to +85°C operating limits.

Part Context

The WBC1-1LC belongs to the Coilcraft WBC series of mini wideband transformers. This family offers various turns ratios and frequency ranges tailored for different RF signal processing tasks. The series is characterized by its small form factor and consistent electrical performance across broad bandwidths, making it suitable for diverse electronic designs requiring reliable signal transmission.

Replacement Considerations

Consult official Coilcraft documentation for direct substitutes within the WBC series. Verify that any alternative part matches the 1:1 ratio, 400 kHz to 600 MHz frequency range, and compatible package dimensions. Cross-reference inductance and DC resistance values to ensure circuit functionality remains unchanged.
