Revised 03/23/06
Available in a variety of impedance versions, Coilcraft’s
WBT Series chip transformers provide wide band pass
performance in a small surface mount package.
The transformers are built on an 1812 size ferrite body
with a ceramic base. They feature 50 V isolation and a
1/4 Watt RF input power rating. The top is a high
temperature material that creates a flat surface for auto
insertion. The parts are packaged in tape and reel for
easy dispensing.
Applications include impedance matching, voltage or
current transformation, DC isolation, balanced/unbal-
anced mixing, matching, power splitting, coupling and
signal inversion.

1. When ordering, please specify termination and packaging codes:
1812WBT1.5-4
LC
Termination: L = RoHS compliant gold over nickel over moly-manganese
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. Factory order only, not stocked (2200 parts per full reel).
2. Inductance is per winding
3. Operating temperature range -40°C to +85°C.
4. Electrical specifications at 25°C. Measurements are referenced to 50 Ohms.
