Ferrite Rod Cores

Ferrite rods also have a colour code hence this article might be useful if you are recycling old parts and see a colour on the end of a ferrite rod this is from my memory of repairing vintage radios many years back. Ferrite is made in different formulas called mixes. Ferroceptor is an older alternative name for a ferrite rod aerial particularly used by philips where the ferrite core would be called a ferroxcube rod a brand name acquired by yageo from philips in the year 2000.

Ferrite rod cores.

Ferrite rod cores and strip cores are primarily used in radio antennas. Rod ferrite core r series is a cylindrical ferrite core can be easily assembly with a spring coil or wind wire directly. Since the tape doesn t always stick to the ferrite it is a good. There were many different colour codes by many different manufacturers but the general rule of thumb was that the aerial input stage coils had blue markings the high frequency.

It s widely used for radio antenna choke coil inductor dc power filter dc signal filter and transformer. The ferrite rod antenna is almost universally used in portable transistor broadcast receivers as well as many hi fi tuners where reception on the long medium and possibly the short wave bands is required. Mouser offers inventory pricing datasheets for ferrite toroids ferrite rings. The mix used will determine the best choking impedance for the desired frequency range.

The ferrite rod aerial or ferrite bar antenna is a form of rf antenna that is almost universally used in portable transistor broadcast receivers as well as many hi fi tuners where reception on the long medium and possibly the short wave bands is required. Winding coils on ferrite rods for example ferrite rod antennas in radio receivers is similar to winding air cored coils but since you can t drill through a ferrite rod you have to rely on the double sided tape or glue to hold the wire tightly. Ferrite toroids ferrite rings are available at mouser electronics. Ferrite cores for the high frequency power supply and high quality communication markets are produced in a variety of shapes and sizes for inductors pulse transformers high frequency transformers and noise filters.

Mixes 31 and 43 are best for hf use 31 is better for the low bands with mix 43 having a slight advantage from 14 to 30 mhz. Due to the open magnetic structure the core can. Notable characteristics of magnetics ferrite materials are high permeability good temperature properties and low. Po box 288 one commercial row wallkill ny 12589 888 fairrite 324 7748 845 895 2055.
