(2) DCR Typ. is only for 755 series while 128 series is of DCR Max. (3) I is the saturation current at which inductance rolls off approximately 30% from its initial (zero DC) value. sat (4) I is the approximate current at which T = 40C. rms Outline Dimensions (mm) Top View Side View Bottom View Recommended Solder Pad Layout Case Size A B C D E F G H I J K L M N P Q R S 128 12.5 12.5 8.05 7.0 5.0 2.5 1.7 4.2 5.5 4.5 2.0 12.8 4.2 4.5 2.0 4.2 5.5 4.5 755 7.7 7.7 4.8 4.1 2.7 1.45 0.80 2.2 2.8 3.1 1.0 7.5 2.2 3.1 1.0 2.2 2.8 3.1 Packaging Embossed Tape and Reel Reel: Diameter: = 13 (330.2mm) Standard: Capacity: Case size 128 = 500 Units Case size 755 = 1,000 Units Ordering Information HM78D - 128 4R7 M LF TR Model Series Tape & Reel Packing Case Size: Lead-Free 128, 755 Inductance Tolerance Inductance Code: K = 10% First 2 digits are significant.
