WidebandTransformers
These wideband transformers are offered in tapped or
untappedconfigurationsinalow-profileDIP-styleplastic
case. They are available in a through-hole version com-
patible with standard DIP sockets and a surface mount
versionthatispackagedintapeandreel.Allpartsfeature
500Visolation,250 mAcurrenthandlingcapabilityanda
1/4 Watt RF power rating. (For a smaller package size,
see our WBC Series.)
Applications include impedance matching, voltage or
currenttransformation,DCisolation,balanced/unbalanced
mixing, matching, power splitting, coupling and signal
inversion.
Customwidebandtransformerswithspecialcombinations
of impedance ratio, insertion loss, frequency response
and current handling are also available.
Free evaluation samples are available by contacting
Coilcraft or by visiting www.coilcraft.com.

1. When ordering, please specify packaging code:
WB25-1LSD
2. Inductance measured at 100 kHz, 0.1 V, 0 Adc on an Agilent/
HP 4192 or equivalent.
3. DCR measured on a micro-ohmmeter.
4. DC imbalance is the maximum difference in current measured at pins
1 and 3 with the source at pin 2. Inductance drop is 15% at maximum
imbalance.
5. Operating temperature range -40°C to +85°C.
6. Electrical specifications at 25°C.
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (500 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.
