## **– Shielded Power Inductors SER1590** 

Designed for high current, low voltage power supply applications, the SER1590 Series offers unmatched electrical performance in an extremely robust package. 

With their heavy flat wire windings, these inductors have exceptionally low DC resistance and offer saturation current ratings up to 50 Amps. Winding to core isolation is 300 Vrms.

1. When ordering, please specify **termination** and **packaging** codes: | ~~————__~~ 

**SER1590-152MLD** 

- **Termination:  L** = RoHS compliant tin-silver-copper over copper. **Special order: T** = RoHS tin-silver-copper over copper (95.5/4/0.5) or **S** = non-RoHS tin-lead (63/37). 

- **Packaging: D** = 13″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge). 

   - **B** = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D. 

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/ HP 4284A LCR meter or equivalent. 

3. DCR measured on a Keithley 580 micro-ohmmeter. 

4. SRF measured using an Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture. 

5. DC current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information. 

6. Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information . When I rms is greater than I sat, I sat is the more critical specification, and I rms is shown in gray type. See Temperature Rise vs Current curve on next page. 

**Designer’s Kit C366** contains 4 of each value **Core material** Ferrite 

**Core and winding loss** See www.coilcraft.com/coreloss 

**Terminations** RoHS tin silver copper over copper. Other terminations available at additional cost. 

**Weight** 4.14 – 5.2 g 

**Ambient temperature** –40°C to +85°C with (40°C rise) I rms current. **Maximum part temperature** +125°C (ambient + temp rise). Derating. **Storage temperature** Component: –40°C to +125°C. Tape and reel packaging: –40°C to +80°C 

**Resistance to soldering heat** Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles 

**Moisture Sensitivity Level (MSL)** 1 (unlimited floor life at <30°C / 85% relative humidity) 

**Failures in Time (FIT) / Mean Time Between Failures (MTBF)** 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 **Packaging** 250 per 13″ reel; Plastic tape: 32 mm wide, 0.4 mm thick, 32 mm pocket spacing, 10.4 mm pocket depth 

**PCB washing** Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. See Doc787_PCB_Washing.pdf. 

7. Electrical specifications at 25°C. 

Refer to Doc 362 “Soldering Surface Mount Components” before soldering
