9B12000013

Crystals Overview

The TXC Corporation 9B12000013 is a through-hole quartz crystal resonator with a nominal frequency of 12 MHz. It features an 18 pF load capacitance and a maximum equivalent series resistance (ESR) of 40 Ohms. The component operates within a temperature range of -40°C to +85°C and maintains a frequency tolerance of ±30 ppm across the full operating range. The unit utilizes the HC-49/S package style, designed for standard wave or manual soldering processes on printed circuit boards.

Crystals Feature Summary

• Through-hole mounting configuration compatible with HC-49/S packages
• Frequency stability maintained at ±30 ppm over the industrial temperature range
• Low equivalent series resistance of 40 Ohms for efficient oscillator drive

Crystals Applications

• Microcontroller clock source generation
• Industrial communication interface timing
• Consumer electronics control circuits

Crystals Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current documentation before procurement. Confirm that the HC-49/S lead form matches the target PCB footprint requirements. Ensure the selected supplier provides traceable RoHS compliance certificates. Cross-reference the datasheet version to confirm the active status of the 18pF load capacitance specification.

Crystals Selection Notes

Select this component when a robust through-hole solution is required for 12 MHz timing applications. The 40 Ohm ESR limit supports standard CMOS oscillator circuits without excessive drive level constraints. Verify that the 18pF load capacitance aligns with the host oscillator circuit design to achieve the specified ±30 ppm accuracy.

Crystals Part Context

This part belongs to the TXC 9B series of general-purpose quartz crystals. The series is characterized by stable performance in standard industrial environments. The HC-49/S package provides mechanical durability suitable for high-vibration applications compared to surface-mount alternatives.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 18pF load capacitance, and HC-49/S package dimensions. Verify that any replacement offers equal or better frequency stability and ESR specifications.
