Toroid Power Inductors – SPT Series

• Toroid winding eliminates stray electromagnetic emissions

• Two versions: Standard, current ratings up to 8 Amps; High

current, with ratings up to 12.2 Amp

Core material

Powered iron

Core and winding loss

See www.coilcraft.com/coreloss

Terminations

RoHS compliant tin-silver over copper. Other

terminations available at additional cost.

Ambient temperature

–40°C to +85°C

Maximum part temperature:

The part temperature should not

exceed +85°C (ambient + self-heating). Prolonged operation above

+85°C may result in a permanent increase in core loss and part failure

due to thermal aging of the core material.

Storage temperature

Component: –40°C to +85°C.

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

PCB washing

Tested with pure water or alcohol only. For other solvents,

see Doc787_PCB_Washing.pdf.

1. When ordering, specify

termination

and

packaging

codes:

SPT20L-112MLD

Termination: L

= RoHS compliant tin-silver over copper.

Special order:

= RoHS tin-silver-copper (95.5/4/0.5) or

= non-RoHS tin-lead (63/37).

Packaging: D

13″ machine-ready reel

EIA-481 embossed plastic tape.

Body size 1:

750 per full reel.

Body sizes 2–3: 350 per full reel.

Body size 4:

300 per full reel.

Body sizes 5–6: 250 per full reel.

Body sizes 7–8: 200 per full reel.

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 tested at 100 kHz, 0.1 Vrms on Agilent/

HP 4192A.

3. SRF measured on Agilent/HP 8753ES network analyzer.

4. DC current that causes the specified inductance drop

from its value without current.

5. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before
