7B-36.000MAAE-T

Crystals Overview

The TXC Corporation 7B-36.000MAAE-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 36.000 MHz. It features a load capacitance of 12 pF and a frequency tolerance of ±30 ppm at 25°C. The component utilizes a 4-SMD, no-lead package with dimensions of 5.00 mm in length, 3.20 mm in width, and a maximum height of 1.05 mm. Designed for base mode operation, it supports an operating temperature range of -20°C to +70°C. The equivalent series resistance (ESR) is specified at 40 Ohms, ensuring stable oscillation within the designated commercial grade applications.

Crystals Feature Summary

• High frequency stability with ±30 ppm tolerance across the operating temperature range
• Optimized electromagnetic interference characteristics suitable for wireless communication environments

Crystals Applications

• Bluetooth portable devices
• Wireless communication equipment
• Mobile phones and PDAs
• USB interface cards

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this variant specifies 12 pF compared to other 7B series options that may use 18 pF. Confirm that the commercial temperature range of -20°C to +70°C aligns with the operational environment requirements. Ensure the 4-SMD footprint matches the board layout constraints. Check RoHS compliance status if required by regional regulations.

Crystals Selection Notes

Select this component when a compact SMD crystal is needed for 36 MHz applications requiring moderate stability. The 12 pF load capacitance requires specific matching capacitors in the oscillator circuit. Consider the ESR value for drive level sensitivity. This part is suitable for consumer electronics where size reduction is critical but industrial-grade wide temperature performance is not mandatory.

Crystals Part Context

This part belongs to the TXC 7B series of surface-mount crystals. The series offers various frequencies and package sizes, typically ranging from 5x3.2mm to smaller footprints. The 7B series is characterized by its small form factor and reliability for high-volume consumer electronics manufacturing, distinguishing it from larger through-hole or wider temperature range industrial variants.

Crystals Replacement Considerations

The 7B-36.000MAAJ-T is a similar 7B series crystal but specifies an 18 pF load capacitance instead of 12 pF. Direct substitution requires verification of the oscillator circuit's external capacitor values to ensure proper frequency accuracy and start-up conditions.
