Due to the toroidal construction, they 21.5 (0.846) Max. exhibit a very low EMI as stray fl ux is kept to a minimum. Typical applications include switching regulators, and power line fi ltering. 0.75 (0.030) 18.0 (0.709) 24.0 (0.945) Max. 1 2 32331C 1.50 (0.059) 10.0 (0.394) XYYWW 4 3 12.7 (0.5) 0.75 (0.030) 4.1±0.5 (0.161±0.020) 5.08±0.3 (0.199±0.012) Package weight: See selection guide.
