| Fixed Inductors for Cellular Phone D310F Inductance Range: 1.0~47H DIMENSIONS 3.8 Max. 1.0 Max. 1.0 Recommended patterns 3.6 0.6 1.4 0.4 2.4 (Unit: mm) Resist Zone (Unit: mm) FEATURES * Low profile (3.8mm Max. square and 1.0mm Max. height). * Clear free-fall drop tests in which it is dropped onto a concrete floor from a height of 1.5m, thus meeting requirements specified for use in cellular phones. * Features an open magnetic circuit, but its thin dimensions result in minimum leakage flux and result in minimum electromagnetic interference generated. * RoHS compliant. * * * * SELECTION GUIDE FOR STANDARD COILS TYPE D310F (Quantity/reel; 0,000 PCS) TOKO Part Number 1033AS-1R0N 1033AS-3R3M 1033AS-4R7M 1033AS-6R8M 1033AS-8R2M 1033AS-100M 1033AS-120M 1033AS-150M 1033AS-220M 1033AS-330M 1033AS-470M Inductance (1) (H) 1.0 3.3 4.7 6.8 8.2 10.0 12.0 15.0 22.0 33.0 47.0 Tolerance (%) 30 20 20 20 20 20 20 20 20 20 20 DC Resistance (2) () Max.

(2) DC resistance is measured with a Digital Multimeter TR6871 (Advantest) or equivalent. (3) Maximum allowable DC current is that which causes a 30% inductance reduction from the initial value, or coil temperature to rise by 40C, whichever is smaller.
