• Compliant with RoHS directives with leaded glass exemption

Crystals Applications

• Portable USB interface cards
• Personal Digital Assistants (PDAs)
• Digital cameras
• Laptop computers

Crystals Procurement Notes

This component is officially discontinued and no longer manufactured by TXC Corporation. Verification of current availability should focus on authorized distributors or surplus suppliers. Buyers must confirm the authenticity of stock through official channels due to the end-of-life status. Replacement planning is recommended as primary sourcing from the manufacturer is unavailable.

Crystals Selection Notes

Engineers selecting this part should verify compatibility with circuits requiring a 13 MHz clock signal and 18 pF load capacitance. The ±30 ppm tolerance suits general consumer electronics but may be insufficient for high-precision timing applications. Consider the 5x3.2mm footprint constraints during PCB layout. Alternative solutions within the same series or newer generations should be evaluated for long-term supply chain stability.

Crystals Part Context

The 7A-13.000MAHJ-T belongs to the TXC 7A series of surface-mount quartz crystals. This series is characterized by its 5x3.2mm package size and glass-sealing technology, which provides superior protection against humidity and mechanical stress compared to resin-sealed alternatives. The series targets compact electronic devices requiring reliable timing sources.
