1. When ordering, please specify termination and packaging codes:
TTWB-1-ALD
Termination: L = RoHS compliant tin-silver-copper over silver-platinum-glass frit.
Special order: S = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic tape, 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. Impedance ratio is for the full primary winding to the full secondary winding.
3. Inductance tested at 130 kHz, 0.1 Vrms, 0 Adc.
4. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Specifications subject to change without notice.
Please check our website for latest information.
