0900BL18B0100001R

Overview

The Johanson Technology Inc. 0900BL18B0100001R is an RF ceramic balun designed for the 800MHz to 1GHz frequency range. It features a 50/100 Ohm impedance configuration and utilizes a 1206 (3216 Metric) surface-mount package with six printed circuit board pads. The component specifies a maximum insertion loss of 1.0dB, a minimum return loss of 9.5dB, and a phase difference of 180° ±10°. It is RoHS3 compliant and classified under EAR99.

Feature Summary

• Provides signal conditioning via balanced-to-unbalanced conversion in the 800MHz to 1GHz band
• Utilizes a compact 1206 surface-mount ceramic form factor for space-constrained designs
• Ensures signal integrity with specified low insertion loss and high return loss performance

Applications

• Wireless sensor networks operating in sub-1GHz bands
• Industrial, Scientific, and Medical (ISM) radio equipment
• Remote keyless entry systems
• Low-power wide-area network (LPWAN) transceivers

Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Johanson Technology Inc. Procurement must rely on secondary market distributors or verified surplus stock. Verify lot dates and physical condition carefully, as availability is limited. Confirm that any offered units are genuine and undamaged before finalizing acquisition.

Selection Notes

Engineers should prioritize alternative components due to the discontinued status of this part. When selecting a replacement, ensure the new balun matches the required 800MHz to 1GHz frequency range and maintains compatible 50/100 Ohm impedance. Verify that the substitute supports the same 1206 footprint to minimize PCB layout changes during design updates.

Part Context

The 0900BL18B0100001R belongs to Johanson Technology's line of ceramic RF baluns, which are passive components used to interface balanced circuits with unbalanced transmission lines. These devices are critical for maintaining signal balance and reducing common-mode noise in wireless communication architectures operating below 1GHz.

Replacement Considerations

The TDK HHM17144A1 is documented as a similar replacement option for this obsolete component.
