FAQ
Yes, but the PCB footprint must be redesigned. Smaller crystals usually have higher ESR, so ensure the MCU driving capability is sufficient.
Technically yes, but it takes more PCB space and longer leads may introduce parasitic capacitance in high-frequency applications.
Ultra-small sizes (e.g., 1612, 1210) require advanced cutting and packaging processes with lower yield rates.
They are usually connected to the metal lid. It is recommended to ground them for EMI shielding and mechanical stability.
Focus on frequency, load capacitance (CL), maximum ESR, and drive level.
Yes. But commercial grade cannot replace industrial grade due to possible instability at extreme temperatures.
Typically refers to crystals operating at -40~+125°C or higher, used in automotive and industrial applications.
Generally yes if key parameters (CL, ESR, PPM) match, but high-reliability applications require validation.
An automotive standard ensuring high reliability, including vibration and temperature resistance.
Ceramic SMD packages are suitable for automation; metal packages (e.g., HC-49S) are cheaper but larger and less suitable for high frequency.
A key parameter for oscillation. Mismatch causes frequency deviation.
C1 = C2 = 2 × (CL - Cs), where Cs is parasitic capacitance (typically 3–5pF).
