Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less. Specifications are subject to change without notice. The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time. Users should verify actual device performance in their specific applications. 0.9 (.035) DIMENSIONS: 4.3 (.169) MM (INCHES) Applications ■ DC/DC converters ■ Notebook computers ■ Digital video cameras ■ HDDs ■ Cellphones ■ Televisions, LCD displays SRF0504 Filter SRN4012 Series Series -- Line Semi-shielded Power Inductors L vs. IDC 32 0.96 12 0.6 24 0.72 9 0.48 6 0.24 3 0 2.4 3.2 0 0 4.0 0 0.56 SRN4012-2R2M 7.2 1.2 4.8 0.6 2.4 0 0.76 1.14 1.52 0 1.90 11.2 2.4 8.4 1.6 5.6 0.8 2.8 0 0 0.34 5.4 10.2 3.6 6.8 1.8 3.4 0 0.78 1.04 0 1.3 Inductance (μH) 13.6 DC Current (A) 0.44 0.68 1.02 1.36 0 1.70 14.4 8.4 10.8 5.6 7.2 2.8 3.6 0 0.44 0.66 DC Current (A) 0 2.20 17.0 13.6 3.6 10.2 2.4 6.8 1.2 3.4 0 0 0.3 0.9 0.6 1.2 0 1.5 DC Current (A) 11.2 0.22 1.76 4.8 0.88 0 1.10 SRN4012-220M 28.0 18.0 0 1.32 0.88 SRN4012-4R7M 6.0 SRN4012-100M 14.0 Temperature Rise (°C) Inductance (μH) 7.2 0.52 0 DC Current (A) 17.0 0.28 4 DC Current (A) 3.2 SRN4012-6R8M 0 8 0.6 0 14.0 DC Current (A) 9.0 0 2.80 Inductance (μH) 1.8 Inductance (μH) 9.6 Temperature Rise (°C) Inductance (μH) 2.4 0.38 2.24 1.2 SRN4012-3R3M 4.0 12.0 0 1.68 12 DC Current (A) DC Current (A) 3.0 1.12 1.8 Inductance (μH) 1.6 Temperature Rise (°C) 0.8 Temperature Rise (°C) 0 16 Temperature Rise (°C) 8 20 2.4 12.0 22.4 9.6 16.8 7.2 11.2 4.8 5.6 2.4 0 0 0.124 0.248 0.372 0.496 0 0.620 DC Current (A) Specifications are subject to change without notice.
