7B-8.000MAAJ-T

Crystals Overview

The 7B-8.000MAAJ-T is a surface-mount quartz crystal manufactured by TXC Corporation, operating at a fundamental frequency of 8 MHz. It features a frequency tolerance and stability of ±30 ppm at 25°C and across the -20°C to +70°C operating temperature range. The component utilizes an 18 pF load capacitance and exhibits a maximum equivalent series resistance (ESR) of 100 Ohms for the 8–12 MHz band. Housed in a compact 4-SMD no-lead package measuring 5.00 mm x 3.20 mm with a maximum height of 1.05 mm, it supports base harmonic operation modes.

Crystals Feature Summary
