MXTVBFI32K768

Crystals Overview

The MXTVBFI32K768 is a surface-mount tuning fork crystal manufactured by Meritek. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20ppm. The component features a load capacitance of 12.5pF and an equivalent series resistance (ESR) of 50 kOhms. It utilizes a 4-SOJ package with a 2.29mm pitch, measuring 9.60mm in length, 4.06mm in width, and having a maximum height of 3.60mm. The device supports fundamental mode operation and functions within a temperature range of -40°C to +85°C.

Crystals Procurement Notes

Verify the specific suffix 'B' or absence thereof against the target design requirements, as package dimensions vary between variants. Confirm RoHS compliance status prior to integration, as documentation indicates non-compliance for this series. Ensure the 12.5pF load capacitance matches the host circuit's oscillator specifications to maintain the stated ±20ppm accuracy. Validate that the 50 kOhm ESR is compatible with the driving circuit constraints.

Crystals Selection Notes

Select this component when a compact surface-mount solution is required for 32.768 kHz timing. The 4-SOJ form factor suits space-constrained PCB layouts compared to through-hole alternatives. Consider the ±20ppm tolerance sufficient for general consumer applications but potentially insufficient for high-precision metrology. Evaluate the operating temperature range against environmental conditions to ensure reliability across the specified -40°C to +85°C span.
