CCFL Transformers
FL3209 parts have been improved.
The new FL3209-5L and FL3209-6L are electrically
equivalent to the FL3209-1L, FL3209-2L, FL3209-3L
and FL3209-4L, and have an improved physical design. We will continue to support existing customers
of the superseded parts.
The FL Series of transformers is designed for use in cold
cathode fluorescent lamp (CCFL) power supplies at opTurns ratio

erating 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.

1. When ordering, please specify a packaging code:
FL2810-1LD
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.
2. Inductance is measured across both halves of the primary.
3. Vrms = continuous voltage.
4. Vinst = instantaneous voltage at startup.
5. Ambient operating temperature range −40°C to +85°C.
6. Electrical specifications at 25°C.
