1. When ordering, please specify

packaging code:

CST4835-150EC

Packaging: C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (500 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 C instead.

D = 13

″ machine-ready reel. EIA-481 embossed plastic

tape (2200 parts per full reel).

2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms,

0 Adc.

3. Maximum volt-time product is for the secondary, based on 2000 Gauss.

4. Primary current of 7 A causes less than 25°C temperature rise from

25°C ambient. Higher current causes a greater temperature rise (see

Temperature Rise vs Current curve).

flowing through the primary. Varying terminating resistance increases or

decreases output Voltage/Ampere according to the following equation:

Core material Ferrite

Environmental RoHS compliant, halogen free

Terminations RoHS compliant silver over nickel over phos bronze.

Weight 115 – 122 mg

Ambient temperature –40°C to +125°C

Maximum part temperature +165°C (ambient + temp rise)

Storage temperature Component: –40°C to +165°C.

Tape and reel 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 500/7

″ reel; 2200/13″ reel; Plastic tape: 12 mm wide,

0.35 mm thick, 8 mm pocket spacing, 3.6 mm pocket depth

PCB washing Tested to MIL-STD-202 Method 215 plus an additional

aqueous wash. See Doc787_PCB_Washing.pdf.
