Resonators Procurement Notes

Verify the specific ordering suffix 'TLF' against the manufacturer's current datasheet to ensure correct package and tape-and-reel specifications. Confirm that the ±0.3% tolerance meets the strict timing requirements of the target application. Check RoHS compliance status if environmental regulations apply to the end product.

Resonators Selection Notes

Select this component when a precise 4.91 MHz reference is required with minimal external components. The integrated capacitor reduces board space and simplifies layout compared to discrete crystal solutions. Ensure the 30 Ohm impedance matches the oscillator circuit design for optimal start-up reliability.

Resonators Part Context

This part belongs to the CRTC series of ceramic resonators from TGS. These devices are engineered as cost-effective alternatives to quartz crystals, offering good frequency stability in a smaller footprint. The series is widely used in consumer electronics and industrial applications where moderate precision is sufficient.

Resonators Replacement Considerations

Direct substitutes must match the 4.91 MHz frequency, 30 pF internal capacitance, and 3-SMD package dimensions. Verify that alternative manufacturers offer equivalent ±0.3% tolerance and compatible operating temperature ranges.
