12M20P2/49SMT

Crystals Overview

The YIC 12M20P2/49SMT is a surface-mount quartz crystal oscillator operating at a nominal frequency of 12 MHz. It features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 50 Ohms. The component exhibits a frequency tolerance of ±30 ppm and operates within a temperature range of -20°C to +70°C. It utilizes the HC-49SMD package, measuring approximately 11.40mm in length and 4.80mm in width. This active component is designed for precise timing applications requiring stable frequency generation.

Crystals Procurement Notes

Verify the specific suffix '49SMT' against official YIC documentation to confirm surface-mount compatibility and pin configuration. Ensure the load capacitance requirement of your circuit matches the 20pF specification. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the ESR value of 50 Ohms with your oscillator circuit design constraints.

Crystals Selection Notes

Select this component when a 12 MHz surface-mount crystal is required with ±30 ppm stability. Consider the HC-49SMD package dimensions for PCB layout constraints. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare the 20pF load capacitance with existing circuit designs to ensure proper oscillation startup and stability.

Crystals Part Context

This part belongs to the 49SMT series of surface-mount crystals from YIC. It shares the physical form factor with other members of the series but differs in frequency and tolerance specifications. The series supports frequencies ranging from 3.000 MHz to 80.000 MHz. It is distinct from through-hole variants like the HC-49US.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 20pF load capacitance, 50 Ohm ESR, and HC-49SMD package. Verify that alternative manufacturers offer the same ±30 ppm tolerance and -20°C to +70°C temperature range. Check for identical pinout and mechanical dimensions to ensure board compatibility.
