When ordering, please specify packaging code: 2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms. 3. Peak primary current drawn at minimum input voltage. C1174-ALD 4. DCR for secondary is with windings connected in parallel. Packaging: D = 13 machine ready reel. EIA-481 embossed plastic 5. Leakage inductance for the primary is with the secondary and drive tape (200 per full reel). Quantities less than full reel windings shorted leakage inductance for the drive winding is with the available: in tape (not machine ready) or with leader secondary windings shorted. and trailer ( 25 charge). 6. Turns ratio is with both secondary windings connected in parallel. B = Less than full reel. In an effort to simplify our part 7. Output of the secondary is with the windings connected in parallel. Bias numbering system, Coilcraft is eliminating the need winding output is 10 V, 20 mA. for multiple packaging codes. When ordering, simply 8.
