Surface Mount Power Inductors
- Magnetically shielded
- Saturation current rating up to 3.72 Amps
- Low DC resistance for greater efficiency
- For high-temperature, AEC-Q200 Grade 1 qualified parts, consider the MSS7341T.
- For a lower profile part with the same footprint, see MSS7331
- AEC-Q200 Grade 3 (−40°C to +85°C)
- RoHS-compliant. 260°C compatible. RoHS compliant matte tin over nickel over phos bronze terminations (current production) or gold over nickel over phos bronze terminations (prior production)
- COTS Plus tin-silver-copper and tin-lead terminations available

| 1 | When ordering, please specify termination and packaging codes: e.g. MSS7341-104MLD | |
| Termination: | L = RoHS compliant matte tin over nickel over phos bronze (current production) or gold over nickel over phos bronze (prior production) Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over gold over nickel over phos bronze or S = non-RoHS tin-lead (63/37) over gold over nickel over phos bronze. |
|
| Packaging: | D = 13" reel, machine-ready EIA-481 embossed plastic tape (1200 parts per full reel). C = 7" reel, machine-ready EIA-481 embossed plastic tape. Special order (300 parts per full reel). B = Less than full reel In tape, 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 using an Agilent/HP 4263B LCR meter or equivalent. | |
| 3 | Tolerances in bold are stocked for immediate shipment. | |
| 4 | DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 5 | SRF measured using an Agilent/HP 8573D network analyzer and a Coilcraft SMD-D test fixture. Details | |
| 6 | Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves. |
|
| 7 | Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves. | |
| 8 | Ambient temperature range: | −40°C to +85°C with (40°C rise) Irms Derating curves |
| 9 | Storage temperature range: | Component: −40°C to +125°C Tape and reel packaging: −40°C to +80°C |
| 10 | Maximum part temperature: +125°C (Ambient + temperature rise) | |
| 11 | Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. | |
| 12 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
| PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info. | ||
