document 323 -1 specifications subject to change without notice. document 323-1 revised 03/07/03 coilcraft?s ser2310 series of flat wire power inductors offers extr emely low dc resistance and very high satura- tion current ratings (up to 50 amps) . the flat core allows for exceptional heat dissipation. these self-leaded inductors have a third mounting leg to ensure positive board adhesion. they are ideal for power supply applications where high current handling is essential and are perfect for low- voltage, high-current dc-dc converters. custom induc- tance values a re also possible. coilcraft designer?s kit c166 contains four samples each of the standard parts shown and four samples of each of our ser1590 high current inductors. contact coilcraft, or order on-line at http://order.coilcraft.com . inductance 2 dcr max srf typ 3 i sat 4 i rms 5 part number 1 20% (h) (ohms) (mhz) (a) (a) ser2310-301mx_ 0.3 0.002 375 50 30 ser2310-701mx_ 0.7 0.003 140 40 28 ser2310-132mx_ 1.3 0.004 86 30 24 smt power inductor - ser2310 series 1. specify packaging code: ser2310-132mx d packaging: d =13 machine-ready reel. eia-481 embossed plastic tape (250 parts per full reel). b = less than full reel. in tape, but not machine ready. to have a leader and trailer added ($25 charge), use code letter d instead. 2. inductance measured at 100 khz, 0.1 vrms, 0 adc using coilcraft smd-d fixture in agilent/hp 4284a impedance analyzer. 3. srf measured using agilent/hp 8753d network analyzer and coilcraft smd-d test fixture. 4. dc current at which the inductance drops 10% (typ) from its value without current. 5. average current for a 40c rise above 25c ambient. 6. operating temperature range -40c to +85c. 7. electrical specifications at 25c. see qualification standards section for environmental and test data.
