Termination: L = RoHS tin-silver over tin over nickel over phos bronze.

Special order: T = RoHS tin-silver-copper (95.5/4/0.5)

or S = non-RoHS tin-lead (63/37).

Pri

Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic

tape (175 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.

Bias

Sync

2. Inductance is measured at 250 kHz, 0.2 Vrms, 0 Adc.

3. DCR for the primary and secondary is with the windings connected in

parallel.

4. Leakage inductance is for the primary windings with the secondary

windings shorted.

5. Turns ratio is with the primary windings and the secondary windings

connected in parallel.

6. These inductors are recommended for 30% ripple current. Ripple less

than 30% may require the use of physically larger inductors. Allowing

higher ripple current to make use of smaller inductors may create a risk

of discontinuous output current.

The primary windings and the

secondary windings are to be

connected in parallel on the

PC board.

7. Operating temperature range –40°C to +125°C.

8. Electrical speciﬁcations at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
