ADT4-5WT+

Balun Overview

The ADT4-5WT+ is a surface-mount core and wire transformer manufactured by Mini-Circuits. It operates within a frequency range of 0.3 MHz to 500 MHz and features a 1:4 impedance transformation ratio with a nominal 50 Ohm system impedance. The component utilizes an SMD/SMT termination type and is housed in the CD637 case style, which incorporates flat leads for board mounting. Designed for robust performance, it supports a minimum operating temperature of -40°C and a maximum operating temperature of +85°C. This device is classified as an RF signal transformer suitable for high-frequency applications.

Balun Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Mini-Circuits or authorized distributors before procurement. Confirm that the CD637 package dimensions align with your PCB footprint requirements. Ensure that the operating temperature range meets your environmental specifications. Cross-reference the part number suffix to confirm the exact termination style and lead configuration intended for your assembly process.

Balun Selection Notes

Select this component when a 1:4 impedance transformation is required within the 500 MHz bandwidth. Consider the CD637 package size constraints during layout planning. Evaluate the thermal performance against the specified -40°C to +85°C operational limits. Compare insertion loss characteristics from the official data sheet against system budget requirements to ensure signal integrity is maintained throughout the desired frequency range.
