• Coupled inductor optimized for xDSL filtering applications
• Can be used as a common mode choke, 1:1 transformer
or in SEPIC applications
Core material Ferrite
Terminations RoHS compliant gold over nickel over moly-manganese.
Other terminations available at additional cost.

Ambient temperature –40°C to +85°C with Irms current, +85°C to
+125°C with derated current
Storage temperature Component: –40°C to +125°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
Packaging 500/7″reel; 2000/13″ reel Plastic tape: 12 mm wide,
0.25 mm thick, 8 mm pocket spacing, 3.9 mm pocket depth
PCB washing Only pure water or alcohol recommended
1. When ordering, please specify termination and packaging codes:
1812DPS-473MLC
Termination: L = Silver-palladium-platinum-glass frit terminations
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 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 C instead.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (2200 parts per full reel).
2. Per winding. Tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. Q measured at 1 MHz.
4. DC current at which the inductance drops 10% (typ) from its value
without current.
5. Current that causes a 40°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
