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 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 6. Electrical specifications at 25°C.

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 in- board configuration for height restricted designs.
