NOTES: [1] Maximum of 4 mA is recommended at temperatures above 250 °F (121 °C). [2] Bias voltage increases with higher constant current. [3] Typical. [4] Conversion Factor 1g = 9.81 m/s². [5] 1Hz = 60 cpm (cycles per minute). [6] The high frequency tolerance is accurate within ±10% of the specified frequency. [7] Zero-based, least-squares, straight line method. [8] 1/4-28 has no equivalent in S.I. units. [9] See PCB Declaration of Conformance PS023 for details. [9]
