Notes
  1. When ordering, please specify termination code: e.g. DO3340H-105KLD
  2. Inductance tested at 10 kHz, 0.1 Vrms, 0 A using an Agilent/HP 4263B LCR meter or equivalent.
  3. SRF measured using Agilent/HP 8753D network analyzer.
  4. Isat: DC current at which inductance drops 30% (typ) from its value without current. For other operating temperatures, use this DCR at Temperature calculator.
  5. Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

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

Packaging:

  • D = 13" reel, machine-ready 
    EIA-481 embossed plastic tape (350 per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
Environmental
Environmental:
RoHS compliant
Ambient temperature range:
−40°C to +85°C with Irms current
Storage temperature range:
Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
Maximum part temperature:
+125°C (Ambient + temperature rise)
Failures in Time (FIT) / Mean Time Between Failures (MTBF):
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332

Soldering/Washing

Moisture Sensitivity Level (MSL):
1 (unlimited floor life at <30°C / 85% relative humidity)
Resistance to soldering heat:
Max three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
