Frequently Asked Questions
What is the load capacitance specification of the HCM49-12.000MABJ-UT crystal?
The HCM49-12.000MABJ-UT has a specified load capacitance of 18 pF. This value must be matched by the two shunt capacitors in the Pierce oscillator circuit to ensure the crystal oscillates at its nominal 12 MHz frequency with the correct accuracy.
Which microcontroller and communication designs can use this 12 MHz crystal?
The 12 MHz frequency of the HCM49-12.000MABJ-UT suits a wide range of microcontrollers including 8051, PIC, AVR, and ARM Cortex-M devices that accept a 12 MHz external clock input. It is also used in USB Full Speed interfaces and UART clock circuits that derive 9600 to 115200 baud rates from a 12 MHz reference.
How does the SMD HC-49/US package of this crystal compare to the through-hole HC-49 variant?
The HC-49/US SMD package used in the HCM49-12.000MABJ-UT is a low-profile surface-mount version measuring approximately 11.35 mm x 4.65 mm, compared to the taller through-hole HC-49 package. SMD mounting allows reflow soldering and reduces the overall PCB height, which is critical in compact electronic assemblies.
Is the HCM49-12.000MABJ-UT compliant with RoHS environmental directives?
Yes, the HCM49-12.000MABJ-UT is lead-free and RoHS compliant as indicated by the UT suffix in the part number. It is suitable for use in environmentally regulated product designs targeting the EU, Japan, and other markets with lead-free requirements. Operating temperature typically spans -20°C to +70°C for standard commercial grade.
