TB0474A

Overview

The TB0474A is a Surface Acoustic Wave (SAW) band-pass filter manufactured by TST. It operates at a center frequency of 70 MHz with a bandwidth of 35 MHz. The component features an insertion loss of 20 dB and is designed for general-purpose RF applications. It utilizes a 12-SMD, no-lead package with a maximum height of 1.80 mm, suitable for surface mount technology.

Feature Summary

• Surface acoustic wave construction for precise frequency selection
• Band-pass filtering capability centered at 70 MHz
• Compact surface-mount package design

Applications

• General purpose RF signal processing
• Intermediate frequency filtering in communication systems
• RF front-end modules requiring 70 MHz selectivity

Procurement Notes

Verify the manufacturer designation as Tai-Saw Technology Co., Ltd. or TST when sourcing. Confirm the package type is SM13365-12PAD. Ensure the datasheet specifies the 70 MHz center frequency and 35 MHz bandwidth to match system requirements. Check for active status availability from authorized distributors.

Selection Notes

Select this component for applications requiring a fixed 70 MHz center frequency. The 35 MHz bandwidth defines the passband characteristics. Consider the 20 dB insertion loss impact on signal strength. The surface-mount form factor dictates PCB layout constraints. Verify compatibility with existing RF circuit impedance matching networks.

Part Context

This part belongs to the SAW filter category produced by Tai-Saw Technology. These components are typically used in radio frequency circuits where size and performance are critical. The TB0474A represents a specific configuration within their portfolio for intermediate frequency applications.

Replacement Considerations

Cross-reference with other 70 MHz SAW filters from Tai-Saw Technology. Verify pinout compatibility if substituting with similar packages. Ensure bandwidth and insertion loss specifications meet the original design intent before replacing.
