7M-25.000MEIV-T

Crystals Overview

The 7M-25.000MEIV-T is a surface-mount quartz crystal oscillator manufactured by FTS, operating at a fundamental frequency of 25 MHz. It features a compact 3.2 mm x 2.5 mm x 0.7 mm SMD package with four solder pads. The component exhibits a frequency tolerance of ±10 ppm at 25°C and ±20 ppm over the industrial temperature range of -40°C to +85°C. It utilizes an 8 pF load capacitance and has an equivalent series resistance (ESR) of 50 Ohms. The device is RoHS compliant and lead-free.

Crystals Procurement Notes

Verify manufacturer authenticity through official channels. Confirm RoHS compliance status matches current regulatory requirements. Ensure ESD handling protocols are followed during storage and assembly. Cross-reference datasheet specifications against design requirements before final procurement decisions.

Crystals Selection Notes

Select this component when a 25 MHz reference with ±10 ppm initial accuracy is required. The 8 pF load capacitance must match the oscillator circuit design. Consider the 50 Ohm ESR for drive level compatibility. The 3.2x2.5 mm footprint suits space-constrained PCB layouts requiring surface mount technology.

Crystals Part Context

This part belongs to the 7M series of surface-mount crystals from FTS. The series offers various frequency options in a standardized small outline package. The MEIV suffix typically denotes specific tolerance and load capacitance configurations within the product line, distinguishing it from other variants like METE or MAHJ.

Crystals Replacement Considerations

Direct substitutes include 7M-25.000MAHJ-T (TXC, 18pF/30ppm) and 7M-25.000METE-T (FTS, 12pF/10ppm). Verify load capacitance and tolerance differences impact circuit performance before substitution.
