MAGNETIC CHARACTERISTICS over operating voltage range.

NOTES: 1. Magnetic flux density is measured at most sensitive area of device,

nominally located 0.014” (0.37 mm) below the branded face of the package.

2. Typical Data is at VCC = 12 V and TA = +25

°C and is for design information only.

3. As used here, negative flux densities are defined as less than zero (algebraic convention).
