Overview
The Coilcraft WBC1-1TLC is a surface-mount mini wideband transformer designed for frequencies between 250 kHz and 750 MHz. It features a ferrite core with an inductance of 9.5 uH and supports a maximum DC current of 36 mA. The component has a maximum DC resistance of 75 mOhms and a power rating of 250 mW. It provides 300 V isolation voltage and operates at temperatures up to +85 C. The package dimensions are 4.45 mm x 4.19 mm x 3.05 mm.
Feature Summary
- Surface mount construction for automated assembly
- Wideband operation across 250 kHz to 750 MHz
- Ferrite core material for magnetic performance
Applications
- Impedance or isolation transformer applications
- Automotive LED driver magnetics
- Power injection inductors for 10BASE-T1 PoDL
Procurement Notes
Verify the specific suffix 'TLC' against the manufacturer's official datasheet to confirm the exact winding configuration and tolerance specifications. Ensure the selected variant matches the required impedance ratio and physical footprint constraints for the target PCB layout. Cross-reference the maximum operating temperature and isolation voltage ratings with system safety requirements before finalizing the procurement order.
Selection Notes
Select this component when a compact, surface-mount wideband transformer is required for high-frequency signal transmission. Consider the 36 mA maximum DC current limit and 75 mOhms resistance for low-power signal paths. Evaluate the 4.45 mm x 4.19 mm footprint against available board space. Confirm compatibility with the intended frequency range of 250 kHz to 750 MHz for the specific application circuit.
Part Context
The WBC1-1TLC belongs to the WBC series of SMT mini wideband transformers manufactured by Coilcraft. This series includes various configurations such as tapped or untapped windings. The part is designed for applications requiring small form factors and reliable RF performance. It serves as a specialized magnetic component for modern electronic designs needing wideband signal integrity.
Replacement Considerations
Consult the official Coilcraft documentation for direct substitutes within the WBC series. Verify that any alternative part maintains the same 1:1 ratio and frequency range. Ensure mechanical compatibility with the existing footprint.
