Banggood 50 ohm BNC feed-through terminator - a quick review

<< < (10/15) > >>

Hydron:
I bought four and changed one to 4*200R, mostly for added power handling. Not worried about use over a few hundred MHz so parasitics aren't likely to be a problem.

Just a warning - be careful not to heat them up too much, the plastic softens easily.

If anyone decides that they want something nicer, then RS has some own-brand ones for about £10 which are silver plated and much better made (at least externally).

bjcuizon:
Yeah, just but be careful with the RS one. I've bought one of those and the male bnc's locking mechanism went loose right away after mating it once with a bnc jack. And also, they specified the VSWR on its online datasheet to be 1.7:1 @ 300MHz :(...Oh well, it should work to maybe around a couple of hundred megahertz.

MF-jockey:
On 18.Dez.2018 I have ordered two of this feed-through terminators:
https://www.ebay.de/itm/2PCS-P7001-BNC-Device-Q9-Adapter-Feed-Through-Terminator-Wholesale/312203578748
On 28.Dez.2018 I received it, but both were broken. From center to shell both have infinitely resistance.
I told the seller and ask for good parts, but he wants to give me a refund.


exe:
I bought similar terminators, one had 50Ohms, another one was 75. I open the latter, it was made of three 150Ohms resistos. Apparently one didn't make a contact, but visual inspection didn't find any problems at all. Soldering looked good, it's still a mystery what happened. Occasionally the broken part was measuring 50 Ohms. So, I suspect there is an internal crack or something. If/when I have time, I'll try to inspect it with a microscope (I don't remember if I did that before).

Microcheap:
I got a pair of these feed through terminators https://www.aliexpress.com/item/P7001-2PCS-High-quality-BNC-to-BNC-Female-seat-50KY-50-ohm-matching-device-Q9-adapter/32661228102.html

It has 3x 150 ohms resistors. You may note the wrong footprints on the PCB, that's because they are reusing the PCB from another product (20:1 attenuator)
