FL Series
CCFL Transformers
| New RoHS part numbers are shown. Lead was removed from terminations. The second to the last character is now L to indicate RoHS compliance. (View old data sheet.) |
 |
| 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 We will continue to support existing customers of the superseded parts. (View data sheet with superseded parts.) |
- Designed for Cold Cathode Fluorescent Lamp power supplies operating up to 100 kHz.

- Designs for Royer and full-bridge topologies
- Three different SMT packages
- Package 5 provides in-board mounting for height restricted designs
- RoHS-compliant. 260°C compatible.

| 1 | When ordering, please specify packaging code: e.g. FL2810-1LD | |
| Packaging: |
D = 13″ machine ready reel. EIA-481 embossed plastic tape. Package 1: 400 parts per full reel. Package 4: 800 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 temperature range: | –40°C to +85°C |
| 6 | Storage temperature range: | Component: –40°C to +85°C T&R packaging: –40°C to +80°C |
| 7 | Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. | |
| 8 | Windings to core isolation is 1500 Vrms for all parts. Isolation is tested for one minute. For Schematic B, primary is not isolated from the secondary. |
|
| 9 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
