TC0597A

Overview

The TC0597A is a Surface Acoustic Wave (SAW) resonator manufactured by TST. It operates at a center frequency of 640 MHz with a nominal impedance of 50 Ohms and a frequency tolerance of ±35kHz. The component utilizes a 6-SMD, No Lead package with dimensions of 3.00mm x 3.00mm x 1.40mm. It supports a surface mount installation type and functions within an operating temperature range of -40°C to +85°C. The device is RoHS3 compliant and classified under ECCN EAR99.

Feature Summary

• Utilizes Surface Acoustic Wave technology for stable resonance
• Designed for surface mount integration in compact layouts
• Operates reliably across extended industrial temperature ranges

Applications

• RF signal generation circuits
• Frequency reference modules
• Wireless communication transceivers

Procurement Notes

Verify the specific ordering suffix required for your packaging preference, such as Tape and Reel, Cut Tape, or Digi-Reel. Confirm that the 6-SMD footprint matches your PCB design constraints. Ensure the 640 MHz frequency aligns with system requirements. Check RoHS3 compliance documentation if environmental regulations apply. Validate the -40°C to +85°C thermal rating against your operational environment.

Selection Notes

Select this component when a precise 640 MHz reference is needed in a small form factor. The 50 Ohm impedance suits standard RF transmission lines. Consider the ±35kHz tolerance for frequency stability needs. The wide temperature range allows use in harsh environments. Verify that the SAW technology meets phase noise and Q-factor requirements for the specific application.

Part Context

This part belongs to the TST SAW resonator family, designed for high-frequency applications. It serves as a passive frequency-determining element in electronic circuits. The SM3030-6PAD package offers a balance between performance and board space efficiency. It is distinct from oscillators as it requires external circuitry to generate signals.

Replacement Considerations

Direct substitutes must match the 640 MHz frequency, 50 Ohm impedance, and 6-SMD package. Verify equivalent tolerance and temperature ratings. Cross-reference pinout compatibility if available. Consult manufacturer databases for updated series replacements.
