TRS2-252+

Overview

The TRS2-252+ is a mini unbalanced-to-unbalanced RF transformer manufactured by Mini-Circuits. It operates within a frequency range of 4 MHz to 2.5 GHz and features a 1:2 impedance ratio with a primary impedance of 50 Ohms. The device exhibits an insertion loss between 0.98 dB and 1.71 dB, alongside a return loss ranging from 17.37 dB to higher values. It supports a maximum power handling of 0.35 W and a current rating of 30 mA. Housed in a compact surface-mount package measuring 0.2 inches on all sides, it utilizes a no-lead SMD termination style suitable for automated assembly.

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update electrical characteristics or mechanical drawings over time. Confirm that the component matches the required 1:2 ratio and 50-Ohm impedance specifications for your circuit design. Ensure compatibility with your PCB soldering profile for no-lead SMD packages. Cross-reference the part number TRS2-252+ against official Mini-Circuits catalogs to avoid counterfeit components.

Selection Notes

Select this component when a wideband unbalanced-to-unbalanced transformation is required within the 4 MHz to 2.5 GHz range. It is appropriate for designs prioritizing minimal board space due to its small physical dimensions. Consider the insertion loss and return loss specifications to ensure they meet system signal integrity requirements. Verify that the 0.35 W power handling capacity is sufficient for the intended application signals.
