Balun Procurement Notes

Verify that the specific part number suffix matches the required impedance and frequency specifications for your circuit design. Confirm that the surface-mount package dimensions align with your PCB footprint requirements. Ensure that the operating temperature range meets the environmental conditions of the intended application. Cross-reference the manufacturer's latest datasheet to confirm compliance with RoHS standards and other regulatory requirements before finalizing procurement orders.

Balun Selection Notes

Select this component when a 75 Ohm to 75 Ohm transformation is required for signals between 5 MHz and 3 GHz. The choice is appropriate for designs prioritizing a small 3.81 mm cubic footprint over larger through-hole alternatives. Consider the 30 mA DC current limit and 250 mW power rating to ensure the component remains within safe operating limits during peak signal conditions.
