WBC2-1TLC

Overview

The Coilcraft WBC2-1TLC is a surface-mount wideband transformer designed for RF applications. It operates within a frequency range of 0.2 MHz to 500 MHz with a 1:2 impedance ratio. Key electrical specifications include an insertion loss of 0.5 dB, a current rating of 250 mA, and a power rating of 250 mW. The device features primary and secondary DC resistances of 120 mOhms and 150 mOhms, respectively. It utilizes a ferrite core and supports an operating temperature range from -40°C to higher limits, suitable for industrial and audio signal processing environments.

Feature Summary

• Wideband operation covering 0.2 MHz to 500 MHz
• Surface mount construction for automated assembly
• Ferrite core material for efficient magnetic coupling
• Low insertion loss characteristics

Applications

• Impedance matching in RF circuits
• Signal isolation in audio equipment
• Industrial control systems

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's latest documentation to confirm pinout orientation and tape-and-reel packaging details. Ensure the selected variant matches the required DC resistance values of 120 mOhms and 150 mOhms for your circuit design. Cross-reference the 250 mA current rating with your system's maximum load requirements to prevent saturation or overheating during operation.

Selection Notes

Select this component when a compact, surface-mount solution is required for frequencies up to 500 MHz. The 1:2 turns ratio makes it suitable for specific impedance transformation needs rather than standard 1:1 isolation. Consider the 250 mW power rating and 250 mA current limit when designing for high-power RF stages. The ferrite core selection indicates suitability for general-purpose wideband applications rather than specialized high-frequency microwave bands.

Part Context

This part belongs to the Coilcraft WBC series of SMT mini wideband transformers. These components are engineered for space-constrained designs requiring reliable signal transmission across broad frequency spectra. The series typically includes various impedance ratios and mounting options, with the WBC2-1TLC specifically offering a 1:2 configuration optimized for mid-range RF and audio signal integrity.

Replacement Considerations

Direct substitutes within the same family include other WBC2 variants with different impedance ratios such as WBC2-1TL or WBC2-1TC, provided the 1:2 ratio requirement can be adjusted. Verify that any replacement maintains the same 0.2-500 MHz bandwidth and surface-mount footprint compatibility.
