BS EN 60444-8:2017 PDF

What is BS EN 60444-8 - Measurement of quartz crystal unit parameters about? BS EN 60444-8 is the eighth part of a multi-series that covers the measurement of quartz crystal unit parameters. BS EN 60444-8 describes test fixtures suitable for leadless surface-mounted quartz crystal units in enclosures as defined in IEC 61837 . These fixtures allow the measurement of resonance frequency, resonance resistance, and equivalent electrical circuit parameters L1, C1, and C0 using the measurement techniques specified in IEC 60444-5 and for determining load resonance frequency and load resonance resistance according to IEC TR 60444-4...
