For Linear Technology LT1725

Isolated Flyback Controller

SMT Power Transformer

• Can be used in isolated and nonisolated designs

• Operates with 36 – 72 Volts input; can be used for PoE.

• 1500 Vrms isolation between the primary and the secondary

Core material Ferrite

Terminations RoHS tin-silver over tin over nickel over phos

bronze. Other terminations available at additional cost.

Weight 5.1 g

Ambient temperature –40°C to +125°C

Storage temperature Component: –40°C to +125°C.

Packaging: –40°C to +80°C

Resistance to soldering heat Max three 40 second reflows at

+260°C, parts cooled to room temperature between cycles

Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /

85% relative humidity)

Failures in Time (FIT) / Mean Time Between Failures (MTBF)

38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332

Packaging 200 per 13″ reel Plastic tape: 44 mm wide,

0.35 mm thick, 28 mm pocket spacing, 9.6 mm pocket depth

1. When ordering, please specify packaging code:

C1048-ALD

4. DCR is for both windings of the secondary connected in parallel.

5. Leakage inductance is for the primary winding with the secondary

windings shorted.

6. Turns ratio is with the secondary windings connected in parallel.

7. Output is with the secondary windings connected in parallel. Output of

the bias winding with a 15 V, 0.2 A.

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

tape (200 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.

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

9. Electrical specifications at 25°C.

2. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.

3. Peak primary current drawn at minimum input voltage.

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