(2) The saturation current (Isat) is the current at which the inductance will be decreased by 20% from its initial (zero DC) value. (3) The heating current is the DC current, which causes the component temperature to increase by approximately 50°C. This current is determined by soldering the component on a typical application PCB, and then applying the current to the device for 30 minutes. (4) Core Loss approximation is based on published core data: Core Loss (Pfe) = K1 * (f)1.338 * (K2∆I)2.2546 Where: core loss in watt f = frequency in kHz K1 and K2 = core loss factor ∆I = delta I across the component in Amp. K2∆I = one half of the peak to peak flux density across the component in Gauss Packaging Standard: Embossed Tape & Reel Reel: Diameter: = Capacity: Case size 10,20,25,30,31,32,33,34 = Case size 35,40,43,45,50,60 = www.bitechnologies.com 13” (330.2mm) 500 Units 400 Units 2009/10 EDITION MAGNETIC COMPONENTS SELECTOR GUIDE We reserve the right to change specifications without prior notice. 87 Electrical Characteristics @ 25°C (A) Case size 10, 20, 25, 30 & 40 Inductance vs. Current Characteristics Inductance Rolloffvs. Current Characteristics (B) Case size 50 & 60 Inductance vs. Current Characteristics Inductance Rolloffvs. Current Characteristics 88 MAGNETIC COMPONENTS SELECTOR GUIDE 2009/10 EDITION We reserve the right to change specifications without prior notice. www.bitechnologies.com Outline Dimensions (mm) Figure 1 Top View Figure 2 Bottom View Top View Recommended Solder Pad Layout Bottom View Note: (1) Dummy terminal should not be used for any electrical connection.
