The device features an equivalent series resistance (ESR) of 40 Ohms and supports a load capacitance of 18pF. It is housed in a compact 2-SMD, No Lead package with dimensions of 5.0 x 3.2mm. The component is designed for high-frequency stability in portable electronic applications.

Crystals Feature Summary

• Fundamental mode operation for precise frequency generation
• Compact surface-mount design suitable for space-constrained PCBs
• Low equivalent series resistance for efficient circuit integration

Crystals Applications

• Portable wireless communication devices
• Mobile test equipment
• Consumer electronics requiring stable clock signals

Crystals Procurement Notes

Verify the specific load capacitance and ESR requirements against your circuit design before procurement. Ensure the 2-SMD package footprint matches your PCB layout. Confirm that the ±50ppm tolerance meets your system's frequency accuracy needs. Check for moisture sensitivity levels if reflow soldering is planned. Validate part status as active to ensure supply continuity.

Crystals Selection Notes

Select this component when a 29.7 MHz fundamental frequency is required with moderate stability. Consider the 40 Ohm ESR for impedance matching. The 18pF load capacitance must align with the oscillator circuit's specifications. Evaluate the 5.0x3.2mm package size against available board space. Compare performance against higher tolerance options if stricter stability is needed.

Crystals Part Context

This part belongs to the CS53B series of surface-mount crystals from Transko Electronics. The series offers various frequencies and package sizes. The CS53B designation indicates a specific form factor and electrical characteristic set. It is distinct from TCXO or VCTCXO series which offer temperature compensation.

Crystals Replacement Considerations

Transko offers the CS63B as a drop-in replacement for discontinued Citizen Finetech CS10 models. For other discontinuations, Transko provides TMM oscillators or OX-P series OCXOs depending on application needs. Verify fit, form, and function compatibility before substitution.
