TB0318D

Overview

The TB0318D is a Surface Acoustic Wave (SAW) filter manufactured by TST, designed for intermediate frequency (IF) applications in RF systems. It operates at a center frequency of 40MHz with a bandwidth of 5MHz and provides an insertion loss of 12dB. The component is housed in a 10-SMD, no-lead package measuring 7.00mm x 5.00mm. It supports a wide operating temperature range from -40°C to +105°C, ensuring reliability in demanding environments.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise signal filtering
• Optimized for intermediate frequency RF applications
• Designed for surface mount assembly via 10-SMD no-lead package

Applications

• RF intermediate frequency filtering
• Pager receiver circuits
• Industrial communication equipment

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as Tape & Reel or Cut Tape, as these affect handling but not electrical performance. Confirm the manufacturer part number matches TST specifications exactly. Ensure the requested quantity aligns with available distribution channels. Check for any specific storage or handling requirements indicated in the official datasheet before procurement.

Selection Notes

Select this component when a 40MHz center frequency SAW filter is required for IF stages. The 5MHz bandwidth defines the passband characteristics. Consider the 10-SMD package dimensions for PCB layout constraints. Verify that the 12dB insertion loss meets system sensitivity requirements. Ensure the operating temperature range covers the intended environmental conditions.

Part Context

This component belongs to the TST SAW filter series, specifically engineered for RF signal processing. It is distinct from other models like the TB0362A which may have different frequency or bandwidth specifications. The TB0318D is part of a lineup focused on reliable surface acoustic wave filtering solutions for electronic devices requiring stable intermediate frequency performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching center frequency, bandwidth, insertion loss, and package dimensions. Consult official TST documentation or authorized distributors for verified alternatives.
