TB0214B

Overview

The TST TB0214B is a Surface Acoustic Wave (SAW) intermediate frequency filter designed for general-purpose RF applications. It operates at a center frequency of 70 MHz with a bandwidth of 16 MHz. The component features an insertion loss of 14 dB and is housed in a 12-SMD, No Lead surface mount package measuring 13.3 x 6.5 mm. It supports operation within a temperature range of -40°C to +85°C and is available in Tape & Reel packaging.

Feature Summary

• Surface acoustic wave technology for stable intermediate frequency filtering
• Compact 12-SMD no-lead surface mount package design
• RoHS compliant construction

Applications

• General purpose RF signal processing
• Intermediate frequency stages in communication equipment
• Broadcast receiver circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration, as variations may exist between tape and reel or cut tape options. Confirm that the RoHS compliance status matches current regulatory requirements for your target market before finalizing procurement orders.

Selection Notes

Select this component when a 70 MHz center frequency with 16 MHz bandwidth is required for IF filtering. Ensure the system accommodates the specified 14 dB insertion loss. Verify that the 12-SMD footprint dimensions fit the PCB layout constraints and that the operating temperature range meets environmental specifications.

Part Context

This SAW filter belongs to the TST family of radio frequency components. It serves as a specialized passive device for signal conditioning in analog and digital radio systems. The part is distinct from broadband filters due to its narrow 16 MHz bandwidth centered precisely at 70 MHz.

Replacement Considerations

Consult official substitution lists for equivalent SAW filters with matching 70 MHz center frequency and 16 MHz bandwidth. Verify pin compatibility and package dimensions before replacing.
