TC1.5-1+

Balun Overview

The Mini-Circuits TC1.5-1+ is a surface-mount RF transformer designed for single-channel applications within the TC1.5 series. It operates over a frequency range of 500 kHz to 2.2 GHz with a 1:1.5 turns ratio. The device features 50 Ohm primary and secondary impedances, supporting a maximum DC current of 30 mA and a power rating of 250 mW. Housed in a compact 3.81 mm x 3.81 mm x 4.06 mm SMD package, it functions reliably between -20°C and +85°C.

Balun Feature Summary

Balun Procurement Notes

Verify the specific suffix (+) indicates RoHS compliance as per manufacturer documentation. Confirm the operating temperature range (-20°C to +85°C) aligns with environmental requirements. Ensure the 50 Ohm impedance specification matches system design needs. Check that the 30 mA DC current limit is sufficient for the application. Validate the SMD package dimensions against PCB layout constraints.

Balun Selection Notes

Select this component when a 1:1.5 impedance transformation is required within the 500 kHz to 2.2 GHz bandwidth. It is suitable for designs needing 50 Ohm input/output matching in a small footprint. Consider the thermal limits and DC current capacity during circuit planning. This part is appropriate for surface-mount assembly processes requiring high precision.
