Notes

Output of the auxiliary winding is 16 V, 20 mA.
Inductance measured at 100 kHz, 1.1 Vrms, 0 Adc using an Agilent/ HP 4263B impedance analyzer or equivalent.
DCR for the secondary is with the windings connected in parallel
3000 Vrms primary and auxiliary to secondary isolation.

Termination:

L = RoHS compliant tin-silver over tin over copper.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)
