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 cur-

rent ratings up to 50 Amps. Winding to core isolation

is 300 Vrms.

1. When ordering, please specify

termination and packaging codes:

SER1590-102MLD

Termination: L = RoHS compliant tin-silver over copper.

Special order: T = RoHS tin-silver-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).

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 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 Coil-

craft 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

Irms is greater than Isat, Isat is the more critical specification, and Irms

page.

7. Electrical specifications at 25°C.

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

Terminations RoHS tin silver (96.5/3.5) 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)

Irms 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.
