1. When ordering, please specify termination and packaging codes:
PWB-3010-1LD
Termination: L = RoHS compliant tin-silver-copper over tin over nickel over phos bronze.
Special order: S = non-RoHS tin-lead (63/37).
Packaging: C = 7″ machine ready reel. EIA-481 embossed plastic tape, 250 parts per full reel. Quantities less than full reel available: in tape (not
machine ready) or with leader and trailer ($25 charge).
D = 13″ machine ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes.
When ordering, simply change the last letter of your part number from B to C.
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. Measurements are referenced to 50 Ohms.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
