CCFL Transformers
The FL Series of transformers is designed for use in
cold cathode fluorescent lamp (CCFL) power supplies at
operating frequencies up to 100 kHz. With output power
from 3.5 to 6.0 Watts, these transformers are ideal for
LCD backlight applications. They are available in two
different gull wing, surface mount packages and one inboard configuration for height restricted designs.
Free evaluation samples are available by contacting
Coilcraft or ordering them on-line at www.coilcraft.com.

Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape.
Package 1: 400 parts per full reel.
Package 4: 750 parts per full reel.
Package 5: 1000 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.
Inductance is measured across both halves of the primary.
Vrms = continuous voltage.
Vinst = instantaneous voltage at startup.
Ambient temperature range: −40°C to +85°C.
Storage temperature range: Component: –40°C to +85°C
Tape and reel packaging: –40°C to +80°C
Electrical specifications at 25°C.
