WBC4-14LC

Overview

The Coilcraft WBC4-14LC is a surface-mount mini wideband RF transformer with a 1:4 impedance ratio. It operates within a frequency range of 1.5 MHz to 1200 MHz. The component features a ferrite core and supports a maximum DC current of 15 mA. Its maximum DC resistance is specified at 100 mOhms or 50 mOhms depending on the winding configuration. The device is designed for high-temperature applications, functioning reliably between -40°C and +85°C.

Feature Summary

• Miniature surface-mount package design suitable for space-constrained PCB layouts
• Wideband operation covering frequencies from 1.5 MHz up to 1200 MHz
• Shielded construction utilizing ferrite core material for stable performance

Applications

• RF signal distribution networks
• Impedance matching circuits in wireless communication modules
• Broadband amplifier input/output stages

Procurement Notes

Verify the specific datasheet revision and impedance tolerance class prior to ordering. Confirm that the 15 mA current rating aligns with the system's peak power requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the footprint dimensions with the PCB layout to guarantee mechanical compatibility.

Selection Notes

Select this component when a compact solution is required for wideband signal transformation. The 1:4 ratio suits applications needing voltage step-up or current step-down. Consider the low current handling capability for low-power signal paths rather than high-power transmission lines. Evaluate insertion loss characteristics against system noise budget requirements.

Part Context

This part belongs to the WBC series of SMT mini wideband transformers manufactured by Coilcraft. These components are engineered for high-frequency RF applications where small form factors are critical. The series offers various impedance ratios to accommodate different circuit topologies while maintaining consistent electrical performance across broad bandwidths.

Replacement Considerations

The WBC4-14L is a related variant within the same product family. Verify if the 'C' suffix indicates a specific compliance or packaging difference. Direct substitution requires confirming identical pinout geometry and electrical parameters.
