5250BL14B100001T

Balun Overview

The Johanson Technology Inc. 5250BL14B100001T is a ceramic chip RF balun designed for high-frequency signal conditioning in wireless applications. It operates within the frequency range of 5.15 GHz to 5.35 GHz, supporting IEEE 802.11a WiFi standards. The component features a 50 Ohm single-ended input and a 100 Ohm differential output, providing impedance transformation and balanced-to-unbalanced conversion. Packaged in a compact 0603 (1608 Metric) surface-mount device (SMD) form factor, it integrates filtering capabilities to suppress harmonics and out-of-band noise. This design facilitates efficient PCB layout and reliable performance in space-constrained mobile devices.

Balun Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure compatibility with required tape-and-reel packaging specifications. Confirm that the component meets current environmental compliance standards such as RoHS before finalizing procurement orders. Cross-reference the full part number with authorized distributors to avoid legacy or obsolete stock variations.

Balun Selection Notes

Select this component when designing circuits operating strictly within the 5.15–5.35 GHz band. Ensure the PCB layout accommodates the 0603 footprint and maintains ground plane integrity for optimal RF performance. Consider thermal management requirements if multiple high-power RF components are placed in close proximity on the same layer.

Balun Part Context

This balun belongs to Johanson Technology’s BL series of signal conditioning components. These parts typically combine impedance transformation with filtering to simplify RF chain designs. The 5250BL14B100001T specifically targets the 5GHz unlicensed spectrum, offering a solution for manufacturers seeking to reduce component count and board space in modern wireless communication hardware.

Balun Replacement Considerations
