X252040MMB4SI AI Analysis:
Datasheet, Specs, Alternatives & ECAD

It features a 40MHz frequency, 10pF load capacitance, ±10ppm frequency tolerance, and ±20ppm stability over a -40°C to +85°C temperature range.

It is primarily used in smart wearables, TWS (True Wireless Stereo) earbuds, and various IoT applications requiring compact, stable frequency control.

Engineers should review the PCB layout guidelines for crystal placement to minimize parasitic capacitance and ensure the load capacitance matches the driving circuit.

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.
