7A-49.152MAAJ-T

Crystals Overview

The TXC Corporation 7A-49.152MAAJ-T is a surface-mount quartz crystal resonator operating at a nominal frequency of 49.152 MHz. It features an 18 pF load capacitance and a maximum equivalent series resistance (ESR) of 50 Ohms. The component utilizes a 2-SMD, no lead package with dimensions of 5.0 mm in length, 3.2 mm in width, and 1.2 mm in height. It supports a drive level up to 100 uW and offers a frequency tolerance of ±30 ppm within the -20°C to +70°C operating temperature range.

Crystals Feature Summary

• Glass-sealed construction provides enhanced resistance to moisture and environmental stress compared to standard ceramic or resin packages.
• Designed for compatibility with standard SMT assembly processes and reflow soldering profiles.
• RoHS compliant with specific exemptions for glass seal materials.

Crystals Applications

• Portable USB data acquisition cards
• NFC readers
• Small-size IoT devices

Crystals Procurement Notes

Verify current availability status as the component may be subject to discontinuation or limited supply constraints. Confirm RoHS compliance details regarding glass seal exemptions during procurement. Ensure ordering quantities align with manufacturer packaging standards. Validate datasheet specifications against final design requirements before purchase.

Crystals Selection Notes

Select this component when high reliability under thermal cycling is required due to its glass-sealed structure. Suitable for applications where standard ceramic packages exhibit frequency drift after reflow. Ideal for compact designs requiring 3225 footprint dimensions. Consider custom tolerance options if tighter frequency stability than ±30 ppm is necessary for specific clock applications.

Crystals Part Context

This part belongs to the TXC 7A series, which specializes in 5x3.2mm SMD glass-sealed quartz crystals. The series is engineered for robust performance in consumer electronics and industrial applications. It addresses common failure modes associated with humidity ingress and mechanical stress in standard packaged crystals.
