What is a Conical Inductor?

Courtesy of Coilcraft : What is a  Conical Inductor?

What are broadband conical inductors and how do they function?

Off-the-shelf “flying lead” and surface mount broadband conical inductors, Figure 1 andFigure 2, are a special type of broadband RF choke that are used to filter radio frequency (RF) and microwave frequency interference from electronic circuits. At high frequency, the RF choke becomes a high impedance element used to isolate noise or DC from desired signals.

How does a conical inductor function?

An inductor placed in series (in line) with a wire or circuit board trace will impede changes in current, such as AC noise current, by temporarily storing energy in a magnetic field and then releasing it back into the circuit. As current through the inductor changes over time (di/dt) the energy stored in the magnetic field of the inductor creates a voltage (V = L × di/dt) that opposes (impedes) a further change in the current. Regardless of whether the current through the inductor is increasing or decreasing, the magnetic field slows the current’s rate of change. Similar to mechanical energy being damped by a shock absorber, the electrical energy of a noise current “spike” in an RF choke is dispersed over time to reduce its impact. Conical inductors provide high impedance over a very wide range of frequencies.

Why does the inductor have a conical shape?

The conical shape limits the effects of stray capacitance and effectively creates a series of narrow band inductors, resulting in high impedance over a very wide bandwidth. A single conical inductor can replace a series of many narrow band inductors.

What applications are appropriate for conical inductors?

Blocking “noise” in RF circuits

The Federal Communications Commission (FCC) has created standards and certifies electronic devices sold or manufactured in the United States meet the electromagnetic interference (EMI) requirements. Worldwide electromagnetic compatibility (EMC) standards organizations include CISPR, IEC, ISO, and EN. FCC regulations are mandatory and apply to devices such as computer, switched-mode power supplies, television receivers, transmitters, and industrial, scientific, and medical (ISM) devices that emit RF radiation. RF chokes, such as conical inductors, are employed in electrical circuits to reduce EMI by attenuating high-frequency noise in order to meet EMC emission and immunity requirements.

RF chokes, such as conical inductors, are employed in electrical circuits to reduce EMI by attenuating high-frequency noise in order to meet EMC emission and immunity requirements.

Isolating RF signals from a DC bias / broadband filtering

A broadband (wideband) conical bias choke placed in line with the DC bias of an amplifier blocks a wide range of high frequencies from reaching the DC source. In this way, the bias choke injects the DC bias while isolating the AC signal from distortion by any stray AC noise. The critical determination when choosing an RF choke for a bias tee is the frequency range that needs to be blocked. Other key parameters are DC resistance, current requirements, size and cost. This application note from Coilcraft explains how to successfully apply a DC bias onto the RF line of a Bias Tee using broadband chokes.

What Types of RF Chokes Does Coilcraft Manufacture?

Coilcraft has designed and manufactured off-the-shelf surface mount (BCR  Series) and “flying lead” thru-hole mount(BCL Series) broadband conical inductors for ultra-wideband Bias Tee applications up to 40 GHz:

  • The surface mount BCR versions can be automatically pick-and-placed onto a PCB.
  • The “flying lead” BCL style allows precise positioning of the mounting angle. The optimal mounting angle is application-specific. Generally, larger angles result in better higher-frequency performance.
  • Both the BCR and BCL series have a flat bandwidth with high impedance up to 40 GHz and are ideal for bias tees.

For higher current, lower frequency applications, the 4310LC series of wideband bias chokes are available off-the-shelf. The 4310LC Wideband Bias Chokes are used in high current Bias Tee applications up to 6 GHz.

They feature terminals that elevate the inductor body 1.5 mm from the printed circuit board surface and measure just 7.1 mm square with a maximum height of 3.2 mm. This allows standard power management IC packages (e.g., QFN/VQFN) to be mounted beneath the inductor in a 3-D packaging arrangement, reducing overall board space. The XAR7030 is available with inductance values ranging from 0.16 to 10 µH and offers extremely low DCR – as low as 1.26 mOhms.

Cary, IL, USA — Coilcraft offers a broad range of wirewound ferrite beads in standard package sizes from 0201 (0603) to 1812 (4532). Superior attenuation and frequency performance enable smaller solution sizes compared to traditional thick-film chip ferrite beads.

They provide extremely low DCR while maintaining high filtering impedance across a wide bandwidth – up to GHz band.

These features enhance the performance of the choke circuit while potentially reducing board space by replacing a larger chip ferrite bead with an equivalent, or higher-performing wirewound ferrite bead. Coilcraft offers 11 families of wirewound ferrite beads, all of which are RoHS-compliant and halogen free. Three models (the 0603LS0805LS and 1008LS) are qualified to AEC-Q200 Grade 3 standards (-40° to +85°C ambient), making them suitable for automotive and other harsh-environment applications.
