Popis

BS EN IEC 60444-11:2026


This standard BS EN IEC 60444-11:2026 Measurement of quartz crystal unit parameters is classified in these ICS categories:
  • 31.140 Piezoelectric devices
IEC 60444-11:2026 defines the standard method of measuring load resonance frequency fL at the nominal value of CL, and the determination of the effective load capacitance CLeff at the nominal frequency for crystals with the figure of merit M > 4. This edition includes the following significant technical changes with respect to the previous edition: a) key content of withdrawn IEC TR 60444-4 is reproduced as Annex A; b) some formulae in the first edition have been corrected.
