Measured the resistance, 50.0 ohms, can't get much closer than that! Metal construction, certainly durable. Would buy again. Well done!

Works, good price, image is misleading

Five bucks for a 50 Ohm terminator is a great deal. Handy to keep a couple around. I took off one star because the Amazon image shows "50Ω" etched into the body of the terminator but the ones I received were unlabeled. I added a Brother label to each to make up for the deficiency.

Good value for decent budget level 50 Ω feed through terminators

Reviewed in the United States on December 24, 2023

Verified Purchase

Swept each of these (2 in a pack) up to 1.5 GHz and they held up well. The ones I received should be usable approaching 23cm territory. These are only good for low voltages and low power applications.
Really, they are only mediocre terminators. The high rating is for the bang for the buck. Haven't found any better that are not also an order of magnitude more expensive.

Returned the black plastic cheap version of these as they were wildly out of claimed specification and had a very poor response on the VNA useful up to maybe 500MHz. Using those proceeds to order another set of these.

These 50 Ohm BNC(M/F) through terminations (ASIN B07G566JC7) are pretty good for the price. Of course like anything BNC I recommend you use them below 3 GHz or so. Also I'm guessing these will handle one Watt or less. I checked S11 and S21 through 2 GHz and they look OK.

Great value

Reviewed in the United States on January 13, 2024

Verified Purchase

These 50 ohm feed-through terminators work nearly as well as those from Pomona at less than a tenth of the cost. Measured with an HP VNA with one end open, the S11 return loss was better than -20 dB up to 680 MHz and better than -10 dB up to 1500 MHz -- and very smooth. See attached test setup photo and S11 chart. This is worse by just a few dB than the Pomona 4119-50 below 1 GHz.

Note that the proper way to test a 50 ohm feed-through terminator is to leave one end open, as was done here. Don't connect it to an oscilloscope input when characterizing its performance, even if that's how it will be actually be used: above a few tens of MHz, a typical 1 Mohm (nominal) scope input's capacitance (generally around 18 pF) will dominate, and not even the best feed-through terminator in the world would look good on the VNA.

Wrong Value Sent! Check each one!

Reviewed in the United States on April 19, 2024

Verified Purchase

Please be sure to double check the value of ALL units received. I purchased four of these units. Three of them have the correct value of 50 ohms. The fourth has a value of 100 ohms (checked with a calibrated high-precision meter). Because these feed-through terminators are no longer laser etched, it is possible someone packaged the wrong one. If you didn't check each terminator, you could cause significant damage to a device under test not realizing the terminated value is not as expected. It is too much hassle to try and return this for what equates to a $5 part.

Update: The seller offered a refund with no hassle without me asking. Really love customer service like that! I have two others ordered previously that are in spec. They offer great performance for price. If you can get a good pair, it is an unbeatable value.
