Scope

This document specifies the measurement fixtures applicable to leadless surface-mount quartz crystal components defined in IEC 61837 (all parts). These measurement fixtures use the measurement techniques specified in IEC 604445 to measure the (series) resonance frequency, (series) resonance resistance, and equivalent circuit parameters L1, C1, and C0. The load resonance frequency and load resonance resistance are determined in IEC 60444-4 and IEC 60444-11.
