As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example: ABS plastic contains styrene PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP) electrolytic capacitors can contain Ethylene glycol Brass can contain Lead flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA) Aluminum alloys can contain Chromium To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching! |

second test: not an Amidon T-50-2 substitute | |
| I put these toroids in a 4.9 MHz six watt transmitter for the output network. they got real warm, almost hot. I had to retune the network, since the inductance changed after heating up. I took the wire off and wound this same wire onto some Amidon T-50-2 cores. These just got a little warm as usual. So these cores may be a low permeability ferrite. ????? not good for a RF tuned circuit with a little power running through them. | ||

yes, Close to T-50-2 in specs | |
| I ordered these since I read from a review that these are similar to a T-50-2. So I did some measurements to confirm this. I have one of these toroids wound with wire for 7 µH and installed in my 5 watt transmitter at around 5 MHz. It is working as the Amidon powdered iron type T-50-2. So I will order more of these next time as they are useful for me. | ||

Close to T-50-2 in specs | |
| I wound a few turns on one of these and measured the inductance with an LC meter. With 6 turns I got about 0.5 uh, just about the same inductance as 6 turns on a T50-2 core. So these are powdered iron, not Ferrite. Still useful, but Ive stored them in a different bin than I thought I would. | ||
