9B-12.000MAAE-B

Crystals Overview

The 9B-12.000MAAE-B is a fundamental quartz crystal oscillator manufactured by TXC Corporation, designed for through-hole mounting in the HC-49/S package. It operates at a nominal frequency of 12 MHz with a load capacitance of 12 pF and a frequency tolerance of ±30 ppm. The component supports an equivalent series resistance (ESR) of 40 Ohms and functions within a temperature range of -20°C to +70°C. With dimensions of 11.5 mm length, 5 mm width, and 3.68 mm height, it utilizes radial termination for circuit integration.

Crystals Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and distributors may not stock new units. Verify current lifecycle status and source availability carefully before finalizing designs, as replacement parts may be required for production continuity.

Crystals Selection Notes

Select this part only if through-hole assembly and HC-49/S packaging are mandatory for the mechanical layout. Ensure the circuit design accommodates the specific 12 pF load capacitance and 40 Ohm ESR requirements. Consider surface-mount alternatives if space constraints or automated SMT processes are preferred over manual or wave soldering methods.

Crystals Part Context

The 9B series represents a line of fundamental quartz crystals from TXC Corporation, typically utilizing the HC-49/S package. This specific model belongs to that family, distinguished by its 12 MHz frequency and through-hole configuration. It serves as a legacy component for applications requiring robust, standardized crystal oscillators in older or specialized hardware architectures.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz HC-49/S crystals from TXC such as 9B-12.000MAAJ-B, provided electrical parameters match. Cross-manufacturer replacements must verify identical package dimensions, load capacitance, and frequency stability to ensure circuit compatibility.
