5512BL15B100001E

Balun Overview

The Johanson Technology Inc. 5512BL15B100001E is an RF balun designed for the 5.15GHz to 5.85GHz frequency range. It provides a balanced-to-unbalanced impedance transformation with a ratio of 50 ohms unbalanced to 100 ohms balanced. The component utilizes a surface-mount 0805 (2012 metric) package, suitable for compact wireless applications. Key electrical characteristics include a maximum insertion loss of 1.0dB and a minimum return loss of 9.5dB. The phase difference is specified at 180° ±10°. This device operates within a temperature range of -40°C to +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Supports high-frequency operation in the 5.15GHz to 5.85GHz band
• Utilizes a compact 0805 surface-mount footprint for space-constrained designs

Balun Applications

• Wi-Fi 5 (802.11ac) transceivers
• Wireless LAN modules
• Bluetooth low energy devices operating in the 5GHz band

Balun Procurement Notes

Verify the specific ordering suffix against the manufacturer's current global part numbering change documentation. Ensure the requested variant matches the required impedance and frequency specifications for your design. Confirm RoHS compliance status and moisture sensitivity level requirements before finalizing procurement orders.

Balun Selection Notes

Select this component when a 50-ohm single-ended interface must connect to a 100-ohm differential RF path. The 0805 package size is appropriate for standard PCB layouts requiring minimal board area. Consider the 1.0dB insertion loss budget when designing the RF chain for the 5GHz ISM band applications.

Balun Part Context

This balun belongs to Johanson Technology's BL series of integrated passive components. These devices replace discrete LC networks to improve performance consistency and reduce assembly complexity. The 5512BL15B100001E specifically targets the 5GHz wireless spectrum, offering a reliable solution for modern communication standards requiring balanced signal integrity.

Balun Replacement Considerations

Check for direct substitutes within the same 5512BL series family that may offer different impedance ratios or frequency ranges. Verify pin compatibility and thermal characteristics if replacing with components from other manufacturers. Consult official cross-reference lists for validated alternatives.
