Specification Notes
[1] Zero-based, least-squares, straight line method.
[2] Typical.
[3] Transverse sensitivity is typically ≤ 3%.
[4] When used with off ground washer, high frequency specification is typically 2 kHz less on 10% and 3 dB points.
[5] Only when using off ground washer.
[6] See PCB Declaration of Conformance PS023 for details.
