DO1607B Series Backlight Inductors

  • Low profile design - just 0.098" high
  • Designed for backlighting applications
  • High breakdown voltages
  • Flat top for reliable surface mounting
  • Robust temperature deflection prevents damage during solder reflow
  • Custom versions available
  • AEC-Q200 Grade 3 (−40°C to +85°C)
  • RoHS-compliant. 260°C compatible. Electroplated gold (<50 µin) over nickel over moly-manganese terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available
  • Samples of all values are available in Coilcraft Designer's Kit C335

1 When ordering, please specify termination and packaging codes: e.g. DO1607B-685MLC
  Termination: L = Gold over nickel over moly-manganese
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
= non-RoHS tin-lead (63/37).
  Packaging: C = 7" machine-ready reel
EIA-481 embossed plastic tape (750 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" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (2500 per full reel).
2 Inductance tested at 100 kHz, 0.1 Vrms  using an Agilent/HP 4263B LCR meter or equivalent.
3 DCR tested at 25°C on a Cambridge Technology 510-A with Coilcraft CCF859 fixture. For other operating temperatures, use this DCR at Temperature calculator.
4 Isat: DC current at 25°C that causes a 10% (typ.) inductance drop from its value without current.
Temperature derating curves.
5 Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
6 Ambient temperature range: −40°C to +85°C with Irms current.
7 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise)
9 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
10 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
