Low Profile Surface Mount Chokes For Data Line Protection

These small footprint common mode chokes reduce a wide frequency range of unwanted radiated and common mode conducted emissions on balanced twisted pair transmission lines, while passing wanted differential mode DC currents and signals.

With inductance values ranging from 5uH to 4.7mH, identified by laser marking, Datatronic has provided EMI noise suppression for a wide band of problem frequencies. Typical applications include modems, instrumentation, telephone switching equipment and more.

The new DR332 Series features an inductance range of 5 to 4.7 mH with custom values available. The current range is 2.5 to 0.2 amps. The operating temperature range is -40°C to +85°C with a storage temperature range of -40°C to +125°C.

The DR332 Series choke operates over a wide frequency range to more than 100MHz. It also features environmentally friendly laser part marking. The compact surface mount DR332 Series features a small footprint that is 9.15mm long –x- 6.0mm wide x 5.2mm high for the DR332-1 and 4.8mm high for the DR332-2. There are compatible with high-speed assembly equipment, and they are also suitable for high-temperature soldering.

Custom designed DR332 Series chokes can be specified to meet unique circuit requirements. The DR332-1 is priced from $0.26 each and the DR332-2 is priced from $0.21 each in typical production volumes. Lead-time is stock to six weeks. Volume OEM pricing is available upon request.
