1. When ordering, please specify termination and packaging codes:
1812DPS-473M
LC
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.
Core material Ferrite
Terminations RoHS compliant gold over nickel over moly-manga-
nese. Other terminations available at additional cost.
Weight 0.30 – 0.36 g
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

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 600/7
″reel; 2200/13″ 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
Coupled inductor optimized for xDSL filtering applications
