TC0632A

Overview

The TC0632A is a Surface Acoustic Wave (SAW) resonator manufactured by TST, designed for precision frequency control in RF and wireless applications. It operates at a nominal frequency of 500 MHz with a characteristic impedance of 50 Ohms. The component is housed in a surface-mount package measuring 5.0 x 3.5 mm, specifically identified as SM5035-4PAD. It supports a wide operating temperature range from -40°C to +85°C, ensuring reliability in diverse environmental conditions. This single-port resonator serves as a critical passive element for stabilizing oscillator circuits in high-frequency communication systems.

Procurement Notes

Verify the specific package variant SM5035-4PAD against schematic footprints before ordering. Confirm that the 500 MHz frequency aligns with system requirements. Ensure the -40°C to +85°C temperature range meets operational constraints. Cross-reference the manufacturer part number TC0632A with official TST documentation to avoid substitution errors. Validate impedance matching for 50 Ohm systems during design integration.

Selection Notes

Select this component when a 500 MHz SAW resonator is required for compact RF designs. Consider the 50 Ohm impedance for direct interface with standard transmission lines. Evaluate the surface-mount profile for automated assembly compatibility. Assess the temperature range suitability for the intended deployment environment. Compare against crystal alternatives if higher Q-factor or lower phase noise is necessary.
