| Wire Wound Chip Inductors LLB2520 (Previous name FSLB2520) Inductance Range: 1~47H (E-6) FEATURES * Small size fixed inductor of the surface mounted type with a wire-wound structure characterized by a low DC resistance. * It is the most suitable for the decoupling inductor for a small current. * Low profile 1.7mm Max. (1.6mm Typ.) * Wide inductance range from 1 to 47H. * Low DC resistance, about half of TOKO's LLM2520 type with same package size. * Superior solderability and high heat-resistance for reflow soldering. * Excellent environmental and mechanical stability. * RoHS compliant. * * * * * * * * DIMENSIONS Recommended patterns 0.4 2.0 1.7 Max. 1.4 2.5 Inductance ID Type & Rotation ID Tolerance 0.2 0.4 0.5 (Unit: mm) 1.2 1.5 1.2 (Unit: mm) ELECTRICAL CHARACTERISTICS 1~47H (E-6) M ; 20% (1~6.8H) K ; 10% (10~47H) * Inductance Temperature Coefficient 750ppm/C Max. * Operating Temperature Range - 40C~+85C * Storage Temperature Range - 40C~+85C (In case of taping used) (- 40C~+60C) * Inductance Range * Inductance Tolerance * * * * * continued on next page 1.5 Wire Wound Chip Inductors continued from previous page F vs. IMPEDANCE CHARACTERISTICS Notes R : Resistance X : Reactance Z : Impedance #FSLB2520-1R0M (1H) 100000 (Agilent Technologies 4291A + 16192A) #FSLB2520-100K (10H) 100000 (Agilent Technologies 4291A + 16192A) Impedance() 10000 1000 100 10 1 1 10 100 1000 Impedance() 10000 1000 100 10 1 1 10 100 1000 X X Z R Z R Frequency(MHz) Frequency(MHz) #FSLB2520-220K (22H) 100000 (Agilent Technologies 4291A + 16192A) 100000 #FSLB2520-470K (47H) (Agilent Technologies 4291A + 16192A) Impedance() 10000 1000 100 10 1 1 10 100 1000 Impedance() 10000 1000 100 10 1 1 10 100 1000 X Z R X Z R Frequency(MHz) Frequency(MHz) SELECTION GUIDE FOR STANDARD COILS TYPE LLB2520 (Previous name FSLB2520, Quantity/reel; 2,000 PCS) TOKO Part Number #FSLB2520-1R0M #FSLB2520-1R5M #FSLB2520-2R2M #FSLB2520-3R3M #FSLB2520-4R7M #FSLB2520-6R8M #FSLB2520-100K #FSLB2520-150K #FSLB2520-220K #FSLB2520-330K #FSLB2520-470K Inductance (1) Lo (H) 1.0 1.5 2.2 3.3 4.7 6.8 10.0 15.0 22.0 33.0 47.0 Tolerance 20 20 20 20 20 20 10 10 10 10 10 DC Resistance (2) () Max. 0.30 0.38 0.44 0.57 0.68 0.89 1.10 1.70 2.50 3.80 5.40 Rated DC Current (3) (mA) Max. 480 435 390 340 310 295 220 180 160 130 100 Self-resonant Frequency (MHz) Min. 130 95 75 60 50 40 33 28 23 18 15 (1)Inductance is measured with a LCR meter 4291A () Test frequency at 1.0MHz. (2)DC resistance is measured with a Digital Multimeter TR6871 (Advantest) or equivalent. (3)Maximum allowable DC current is that which causes a 10% inductance reduction from the initial value, or coil temperature to rise by 20C, whichever is smaller.
