TB0194B

Overview

The TB0194B is a general-purpose RF Surface Acoustic Wave (SAW) bandpass filter manufactured by TST. It operates at a center frequency of 70 MHz with a bandwidth of 5.1 MHz and an insertion loss of 11 dB. The component is housed in a 12-SMD, no-lead surface mount package measuring 13.30 mm in length and 6.50 mm in width, with a maximum height of 1.80 mm. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) rating of 1.

Feature Summary

• Surface acoustic wave technology for RF signal filtering
• Bandpass characteristic centered at 70 MHz
• Lead-free surface mount construction

Applications

• General purpose RF applications

Procurement Notes

Verify the manufacturer designation as Tai-Saw Technology Co. Ltd. when sourcing. Confirm the specific package variant matches the 12-SMD no-lead requirement. Ensure compliance with RoHS3 regulations is documented for the specific order batch. Cross-reference the part number against official distributor catalogs to confirm current availability status.

Selection Notes

Select this component for designs requiring a 70 MHz center frequency with a 5.1 MHz bandwidth. The 11 dB insertion loss must be accounted for in the system link budget. The 12-SMD footprint requires compatible PCB land patterns. Verify thermal management capabilities align with the specified operating conditions.

Part Context

This SAW filter belongs to the TST RF filter portfolio designed for surface mounting. It serves as a specialized component for radio frequency signal processing. The device utilizes surface acoustic wave principles to achieve its filtering characteristics within a compact form factor suitable for modern electronic assemblies.

Replacement Considerations

The TB0194A is listed as a parameter equivalent substitute from the same manufacturer.
