Current Sense Transformers CST2010
Document 1100-1
Document 1100-1 Revised 04/25/16
1. When ordering, please specify
packaging code:
CST2010-200LD
Packaging: D = 13
″ machine-ready reel. EIA-481 embossed plastic
tape (300 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. Inductance measured between secondary pins at 1 kHz, 0.1 Vrms,
0 Adc.
3. Maximum volt-time product is for the secondary, based on 2000 Gauss.
4. Primary current of 40 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).
5. Terminating resistance (RT) value is based on 1 Volt output with 40 Amps
flowing through the primary. Varying terminating resistance increases or
decreases output Voltage/Ampere according to the following equation:
RT = Vout × Nsec/
Iin.
6 Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Core material Ferrite
Terminations RoHS compliant tin-silver over tin over nickel over phos
bronze
Weight 4.13 g
Ambient temperature –40°C to +125°C
Maximum part temperature +165°C (ambient + temp rise)
Storage temperature Component: –40°C to +125°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 300/13
″ reel; Plastic tape: 32 mm wide, 0.5 mm thick,
20 mm pocket spacing, 10.6 mm pocket depth
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.
