The ROHS compliant DR217 Radial Leaded Inductors provide superior protection against challenging EMI/RFI problems in current handling applications up to 8.4 Amps. The proven, affordable DR217 Series offers extended life in temperatures ranging from -20 to +80°C.

The DR217 series is designed for EMI filters and switching power supplies. Combining durability with high performance, the DR217 series is ideal for commercial and industrial equipment including computers, telecom equipment, power supplies, industrial machinery, factory automation equipment, instrumentation and more.

Depending on the specific model, the DR217 Series Inductors feature an inductance range from 1.0?H to 150 mH. The DCR is specified from 0.008 to 520 Ohms maximum over a maximum current rating from 8.4 to 0.045 Amps. The DR217-0 through DR217-7 Series have minimum Q specifications based on test frequencies from 25.2 kHz to 7.96 MHz.

With their through-hole wirewound coil design, the DR217 Series Inductors come in round packages sized from 0.196 inch (5.0 mm) diameter to 0.551 inch (14.0 mm) diameter, with lead spacing from 0.78 inch (2.0 mm) to 0.295 inch (7.5 mm) depending on the specific model. They are compatible with high-speed assembly equipment, and they are suitable for high-temperature soldering. Tinned leads with leaded solder are also available.

Model DR217 Series Inductors are priced from $0.075 to $0.22 each in typical production volumes. Lead-time is 6 to 8 weeks. Volume OEM pricing is available upon request. Custom designed DR217 Series Radial Leaded Inductors can be specified to meet unique circuit requirements.
