9C-35.328MAAJ-T

Crystals Overview

The 9C-35.328MAAJ-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, operating at a nominal frequency of 35.328 MHz. It utilizes an HC-49/US package and supports fundamental mode operation with a load capacitance of 18 pF. The component exhibits a frequency tolerance and stability of ±30 ppm at 25°C, with an equivalent series resistance (ESR) of 80 Ohms. It functions within an operating temperature range of -20°C to +70°C. The device is lead-free and RoHS compliant, designed for high-frequency pullability and low series resistance in compact electronic assemblies.

• Lead-free manufacturing process compliant with RoHS standards

Crystals Applications

• Personal computers and peripheral interfaces
• Set-top boxes and digital television receivers
• LCD monitors and display controllers
• Cable modems and broadband communication equipment

Crystals Procurement Notes

Verify that the specific order matches the 9C-35.328MAAJ-T designation, as this part number corresponds to a quartz crystal resonator rather than an active oscillator. Confirm the package type is HC-49/US SMD and the load capacitance requirement is 18 pF. Ensure the application circuit supports fundamental mode operation at 35.328 MHz. Check for updated datasheets regarding aging rates and drive level specifications before finalizing the design.

Crystals Selection Notes

Select this component when a standard surface-mount crystal is required for 35.328 MHz applications. The HC-49/US form factor provides a balance between size and electrical performance. Consider the ±30 ppm stability limit against system timing requirements. The 18 pF load capacitance must match the oscillator circuit's effective capacitance. This part is suitable for general-purpose digital logic clocking where ultra-low jitter is not critical.

Crystals Part Context

The 9C series represents TXC Corporation's line of miniature surface-mount quartz crystals. These components are engineered for mass production and offer high reliability in consumer electronics. The 9C-35.328MAAJ-T is part of a broader family offering various frequencies in the same footprint, facilitating inventory management for manufacturers producing multiple product variants with similar mechanical constraints.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/US SMD crystals with identical 35.328 MHz frequency, 18 pF load capacitance, and ±30 ppm stability. Cross-reference with parts from vendors such as ECS or Abracon that specify the same package dimensions and electrical parameters. Verify that any replacement maintains the fundamental mode of oscillation and compatible ESR values.
