Document 383-1 SMT Power Inductors –MSS7341 Series The MSS7341 series is ideal for applications requiring high power and high efficiency such as notebook computers, wireless phones, PDAs and other handheld products. It provides excellent current handling capability in a rugged, low cost part. These magnetically shielded power inductors are designed for high-density mounting and are available on tape and reel for auto-insertion. They are offered in 18 inductance values from 3.3 to 100 µH including values not available in our other power inductor series. Coilcraft Designer’s Kit C185 contains samples of all values shown.

When ordering, please specify packaging code: MSS7341-104MXD Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (1200 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 a Coilcraft SMD-A fixture in an Agilent/HP 4284A impedance analyzer. 3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 4. DC current at which the inductance drops 25% (typ) from its value without current. 5. Average current for temperature rise above 25°C ambient. 6. Storage and ambient operating temperature range −40°C to +85°C. 7. Electrical specifications at 25°C. See Qualification Standards section for environmental and test data. Specifications subject to change without notice.
