Procurement Notes

Verify the specific suffix 'S033' against the manufacturer's official documentation to confirm the exact package dimensions and pin configuration. Ensure that the required operating temperature range aligns with the specified -25°C to +85°C limits for your application environment. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a cost-effective alternative to quartz crystals is needed with moderate stability requirements. The built-in capacitor eliminates external components, reducing board space. Consider the 40 Ohm impedance match with the oscillator circuit to ensure reliable startup. Verify that the SMD3213 footprint fits within the available PCB area constraints.

Part Context

This ceramic resonator belongs to TGS's standard passive component lineup, designed for general-purpose timing applications. It serves as a middle-ground solution between less stable RC oscillators and higher-cost precision quartz crystals. The product line focuses on providing reliable frequency generation for consumer electronics and industrial control systems where size and cost are critical factors.

Replacement Considerations

Direct substitutes must match the 12.5 MHz frequency, 33 pF capacitance, and SMD3213 package. Verify equivalent electrical parameters such as series resistance and tolerance from competing manufacturers like Murata or Abracon before implementation.
