The 7M25000014 from TXC Corporation is a 7M-series surface-mount quartz crystal featuring a nominal frequency of 25MHz, an initial frequency tolerance of ±10ppm, frequency stability of ±10ppm, and a load capacitance of 18pF. As a passive crystal resonator, it operates with an internal or external oscillator circuit to provide a stable clock reference for microcontrollers, communication ICs, networking equipment, and digital systems.
The device is supplied in a compact 3.2 × 2.5mm 4-pad ceramic SMD package with an approximate height of 0.7mm. The TXC 7M series uses a ceramic seam-sealed construction designed for compact, high-density PCB applications requiring stable frequency performance.
At 25MHz, the crystal has a maximum equivalent series resistance of 50Ω, a typical drive level of 100μW, and a maximum shunt capacitance of 3pF. This specific part supports an operating temperature range from -10°C to +70°C.
The component is supplied in tape-and-reel packaging with a standard factory quantity of 3,000 pieces per reel. It is suitable for automated surface-mount assembly and reflow soldering and is RoHS compliant and lead-free.
