Notes
  1. When ordering, please specify packaging code: e.g. SPT20L-112MLD
  2. Inductance tested at 100 kHz, 0.1 Vrms on an Agilent/HP 4192A impedance analyzer.
  3. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using Agilent/HP8753ES network analyzer.
  5. Isat: DC current at which the inductance drops the specified amount from its value without current.
  6. Irms: Current that causes the specified temperature rise from 25°C ambient.

Termination:

  • L = RoHS compliant tin-silver over copper.
  • T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

  • 13" reel, machine-ready
    EIA-481 embossed plastic tape.
  • B = Less than full reel
    On tape not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
Environmental
Environmental:
RoHS compliant
Ambient temperature range:
40°C to +85°C
Storage temperature range:
Component: –40°C to +85°C.
Packaging: –40°C to +80°C
Maximum part temperature:
The part temperature should not exceed +85°C (ambient + self-heating). Prolonged operation above +85°C may result in a permanent increase in core loss and part failure due to thermal aging of the core material.
Failures in Time (FIT) / Mean Time Between Failures (MTBF):
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
