TC1-1T+ – MINICIRCUITS

The TC1-1T+ from Mini-Circuits is a 1:1 impedance ratio, surface-mount core and wire transformer designed for impedance matching and signal isolation applications. Its compact form factor allows for high-density PCB layouts. The “0.4” specification likely refers to the lower end of its usable frequency range, indicating functionality down to at least 0.4 MHz. Electrical characteristics include a nominal insertion loss, typically minimal within its specified bandwidth, and a return loss optimized for maintaining signal integrity. The transformer’s core material and winding configuration are engineered to provide a balanced signal transfer, minimizing common-mode noise and harmonic distortion. The TC1-1T+ is constructed to withstand standard reflow soldering processes, ensuring reliable integration into automated assembly lines. It is commonly employed in applications such as baluns, impedance matching networks, and signal coupling for various RF and IF circuits.
