1. When ordering, please specify

termination and packaging codes:

DT1608C-106MLC

Termination: L = RoHS compliant gold over nickel over moly-manganese.

Special order:

T = RoHS tin-silver-copper (95.5/4/0.5)

or

S = non-RoHS tin-lead (63/37).

Packaging: C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (750 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 C instead.

D = 13

″ machine-ready reel. EIA-481 embossed plastic

tape (2500 parts per full reel).

2. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc.

3. Measured at the rated current. Refer to L vs Current curves for details.

4. Average maximum allowable current. DT Series inductors are designed

for current spikes as high as twice the current rating.

5.

Ambient temperature range: –40°C to +85°C

6.

Storage temperature range: Component: –40°C to +85°C

Tape and reel packaging: –45°C to +80°C

7.

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.

8. Electrical specifications at 25°C.

See Color Coding section for part marking information.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

The Coilcraft DT1608 Series is magnetically shielded

and the materials used provide natural heat sinking. This

allows these parts to be used at relatively high currents.

Even at 150% of rated current, the temperature rise is

less than 15°C.

Because of their “swinging” inductance vs current char-

acteristics, the DT1608 Series can be used as ultra high

L inductors at zero or low current.

For new designs, consider the LPS4018 as an alternative

to this series. The LPS4018 series is more cost effec-

tive, features a smaller footprint, lower profile and better

current handling. We will continue to manufacture and

support the DT1608C indefinitely.
