This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the relative strength of the fi eld is indicated
by the absolute value of B, and the sign indicates the polarity of the fi eld (for example, a –100 G fi eld and a 100 G fi eld have equivalent strength, but
opposite polarity).

Maximum voltage must be adjusted for power dissipation and junction temperature, see Power Derating section.
C
Maximum current limit is equal to the maximum I
Magnetic fl ux density, B, is indicated as a negative value for north-polarity magnetic fi elds, and as a positive value for south-polarity magnetic fi elds.
S
= oscilloscope probe capacitance.
