TC1.5-1X+

Balun Overview

The TC1.5-1X+ is a surface-mount core and wire RF transformer manufactured by Mini-Circuits. It operates within a frequency range of 0.5 MHz to 2.2 GHz, providing a 1:1.5 impedance transformation ratio. The component features 50 Ohm primary and secondary impedances, making it suitable for balanced-to-unbalanced signal conversion. It is housed in a compact 3.81 mm x 3.81 mm x 4.06 mm SMD module package. The device supports a maximum DC current of 30 mA and has a power rating of 250 mW. Operating temperatures range from -20°C to +85°C.

Balun Feature Summary

• Provides direct interfacing between single-ended RF sources and balanced IC inputs
• Utilizes core and wire construction for reliable signal transformation
• Designed for surface mount assembly in compact electronic circuits

Balun Applications

• Interfacing oscillators or modulators with balanced mixer inputs
• Balanced antenna impedance matching systems
• Wideband push-pull amplifier configurations

Balun Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct impedance and frequency specifications. Confirm RoHS compliance status and lead times through authorized distributors prior to ordering. Ensure storage conditions align with moisture sensitivity level requirements to maintain component integrity during assembly processes.

Balun Selection Notes

Select this component when a 1:1.5 impedance transformation is required between 50 Ohm ports. Consider the 2.2 GHz upper frequency limit and -20°C minimum operating temperature for environmental compatibility. Evaluate the physical footprint dimensions against available PCB space constraints before finalizing the design integration.

Balun Part Context
