9B-20.000MBBK-B

Crystals Overview

The TXC Corporation 9B-20.000MBBK-B is a fundamental mode quartz crystal resonator operating at 20 MHz. It features a frequency tolerance of ±50ppm and stability of ±50ppm. The component utilizes a 20pF load capacitance and exhibits an equivalent series resistance (ESR) of 30 Ohms maximum. It is housed in a 2-pin HC-49/S through-hole package, designed for bulk packaging.

Crystals Feature Summary

• Fundamental resonance mode operation ensures stable oscillation characteristics.
• HC-49/S through-hole package facilitates standard PCB mounting processes.
• Low equivalent series resistance supports efficient circuit driving.

Crystals Applications

• General purpose clock signal generation
• Microcontroller system timing references
• Digital logic circuit synchronization

Crystals Procurement Notes

Verify the specific suffix B against official datasheets to confirm package type and tolerance levels. Ensure the ordering code matches the required 20MHz frequency and 20pF load capacitance specifications. Confirm RoHS compliance status with the manufacturer prior to final procurement decisions.

Crystals Selection Notes

Select this component when fundamental mode stability is required for 20MHz applications. The HC-49/S package suits designs requiring through-hole assembly. Verify that the 30 Ohm ESR aligns with the oscillator circuit's drive level requirements to prevent frequency instability or crystal damage.

Crystals Part Context

This part belongs to the 9B series of fundamental crystals from TXC Corporation. The series typically offers standard commercial-grade performance with through-hole packaging options. It serves as a basic timing element for digital systems requiring reliable frequency references without active oscillator circuitry.

Crystals Replacement Considerations

Substitutes must match the 20MHz frequency, 20pF load capacitance, and HC-49/S package dimensions. Verify equivalent ESR values and stability ratings to maintain circuit performance. Check for pin compatibility and mounting hole spacing alignment.
