7B-25.000MAHJ-T

Crystals Overview

The 7B-25.000MAHJ-T is a parallel fundamental quartz crystal manufactured by TXC Corporation, operating at a nominal frequency of 25 MHz. It features a frequency tolerance and stability of ±30 ppm at 25°C and over the operating temperature range. The component utilizes an 18 pF load capacitance and exhibits an equivalent series resistance (ESR) of 60 Ohms. Designed for surface-mount applications, it is housed in a compact 4-SMD, no-lead package measuring 3.2 mm x 2.5 mm with a maximum height of 0.90 mm. The device supports a drive level of 1 µW and functions within a temperature range of -40°C to +85°C.

Crystals Procurement Notes

Verify the specific ordering suffix against official TXC documentation to confirm exact electrical parameters such as load capacitance and tolerance. Ensure compatibility with target circuit impedance requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Cross-reference datasheet revisions to validate current specifications against production batches.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required in space-constrained designs. The 18 pF load capacitance must match the oscillator circuit's external capacitors. Consider the 60 Ohm ESR for driving capability limits. The wide temperature range suits industrial environments. Verify that the 1 µW drive level prevents frequency pulling or aging issues in the specific application context.
