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 | DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
6 | Ambient temperature range: | −40°C to +85°C |
7 | Storage temperature range: | Component: −40°C to +85°C Tape and reel packaging: −40°C to +80°C |
8 | 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. | |
9 | 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. |
|
10 | Electrical specifications at 25°C. | |
Refer to Soldering Coilcraft Components before soldering. | ||
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info | ||
