AV-37.050MAHV-T

Crystals Overview

The AV-37.050MAHV-T is a quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 37.05 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a frequency tolerance of ±30 ppm and stability of ±30 ppm at 25°C, expanding to ±50 ppm across the industrial temperature range of -40°C to +85°C. It utilizes a glass-sealed ceramic package measuring 3.2 mm x 2.5 mm x 0.8 mm and holds AEC-Q200 automotive qualification.

Crystals Procurement Notes

Verify the specific suffix 'HV' against the manufacturer's current datasheet to confirm pin configuration and sealing method. Ensure the selected variant meets the required AEC-Q200 grade for your target application. Cross-reference the ESR value of 60 Ohms with your oscillator circuit design to guarantee proper startup conditions. Confirm RoHS compliance status if restricted substances are a project constraint.

Crystals Selection Notes

Select this component when a fundamental frequency crystal is required for automotive-grade timing applications. The 8 pF load capacitance suits standard CMOS oscillator loads. The 60 Ohm ESR provides a balance between phase noise and drive level sensitivity. Consider the 3.2mm x 2.5mm package size for PCB space constraints in dense automotive assemblies.

Crystals Part Context

This part belongs to the AV series of automotive crystals from TXC Corporation. The series is characterized by glass-sealed packages offering superior humidity resistance compared to standard epoxy-sealed alternatives. The AV series is specifically engineered to meet the rigorous thermal and mechanical shock requirements defined by AEC-Q200 for passenger vehicle electronics.

Crystals Replacement Considerations

Direct substitutes include other AEC-Q200 qualified 37.05 MHz crystals with identical 8 pF load capacitance and similar physical dimensions. Verify that alternative parts maintain the same 60 Ohm ESR and glass-seal technology to ensure equivalent performance in automotive environments.
