1210PoC Series
Power Injection Chokes for PoC

  • Optimized for AEC-Q200 power over coax (PoC) applications
  • Small size to reduce board area of overall system solutions
  • AEC-Q200 Grade 1 (−40°C to +125°C)
  • High impedance (≥ 1kOhm) maintained over a wide band frequency range
    to isolate AC signal from the DC power
  • RoHS-compliant matte tin over nickel over silver platinum-glass frit.

1 When ordering, please specify packaging code: e.g. 1210POC-223MRC
Packaging: C = 7" machine-ready reel
EIA-481 embossed plastic tape. 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.
2 Inductance tested at 100 kHz, 0.1 Vrms, 200 mA DC using HP4263 w/SMD-B test fixture or equivalent.
3

DCR measured  at 25°C using a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.

4 SRF measured using an Agilent/HP 5071C network analyzer and a Coilcraft SMD-D test fixture.
5 Isat: DC current that causes 30% inductance drop from its initial value at 200 mA at specified temperature.
Temperature derating curves.
6 Irms: Current that causes a 40°C rise at 25°C. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
7 Irms: Current that causes a 40°C rise at 85°C. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
8 Irms: Current that causes a 15°C rise at 125°C. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
9 Ambient temperature range: −40°C to +125°C with (15°C rise) Irms Derating curves
10 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
11 Maximum part temperature: +140°C (Ambient + temperature rise)
12 Resistance to soldering heat: Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles.
13 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
