In contrast, /I/ think that it is thermal foam ('gap pad'), and that the board is designed to be mounted flush against a metal surface. But I can only imagine the mounting system: you haven't given us a picture.

I would guess it is NXP BGA7130, an RF power amp. I can't find anything about package marking in the datasheet, but you could ask NXP support to verify.

A manufacturer with a matching logo is Nanjing Micro One. (Here's a link showing their logo on LCSC.) Updated: Further investigation shows that your device with top marking V1TF is the Nanjing Micro One ME6209A33M3G 3.3 V LDO, which has a maximum input voltage listed in its datasheet (both maximum operational and absolute maximum) of 18 V. The top code is ...

The closest I can appear to come is the RAA214401 from Renesas. The logo appears similar to what you've drawn as well but as winny has requested in the comments it would be more helpful if you could post an actual photo of the IC in question and if you happen to know what pins perform what function (i.e. GND, V+, Vin) which is something you should be able ...

I suggest many of these choices for an LDO 3.3V will be suitable for replacement. https://www.mouser.com/Semiconductors/Power-Management-ICs/Voltage-Regulators-Voltage-Controllers/LDO-Voltage-Regulators/_/N-5cgac?P=1z0wa2eZ1z0z5la

Those connectors are known as KNX or EIB connectors. They are quite popular in smart home applications. They allow the user to insert the cable directly inside the connector: Img Src: KNX Association - KNX Basics Course There's no matching connector or receptacle for KNX/EIB connectors. Just insert the stripped cable inside.

According to IC Master 1984, SFC2741 (made by Thomson-CSF) is an alternative for the μA741 op amp, and SFC710 is an alternative for the μA710 comparator. ETA: found a cross-reference that confirms these chips are equivalent:- SGS THOMSON-CSF (SESCOSEM) Linear integrated circuits ( Circuits intégrés linéaires) 1976

It looks like the part you're asking about may be a TLV700 200mA LDO Regulator the pins matchup with the drawings and the ODM top marking shows on a couple of variants:

I was looking for the same IC and found the WS9002. I've checked the pin out and it is correct. Use Google to help with the datasheet: https://datasheetspdf.com/pdf-file/1351316/Winsemi/WS9002/1 Please, reply if you find any replacement or a easy way of dimming it.

Looks like an obsolete Bourns Pot. 10k. the shafts are plastic now. But you need to define the bottom pins , stereo, linear or log etc 1/4" 26 or 32 tpi Most are metric now You can find an equiv on D-K site or Mouser https://www.mouser.com/ProductDetail/Bourns/PTV112-4220A-B103?qs=h2IHEVivlqBiDxqtaFbOxg%3D%3D Compare dimensions on datasheet with ...

Lots of these connectors but that one appears to be keyed, possibly a GPU. Molex Micro-fit

That looks to be a very standard computer power connector, of the type originally made by Molex (under the series name Mini-Fit Jr), and now made by several manufacturers. Many people simply call them Molex connectors. Here's a large selection of them. (image source)

Kind of a blind shot here, but that seems to be a SOD package. So in this case it would be some kind of diode. Not sure how to decode the label.

As Spehro explained, it looks like a thermistor touching (i.e. thermally-coupled to) the resistor next to it (R20) (notice the diagonal line on the silkscreen between the two components, also suggesting a coupling between them). However there is one more piece of evidence not yet mentioned, which adds extra confirmation. Notice the reference designator next ...

I agree that this is probably a thermistor and it appears to be thermally coupled to the 1.78K 1% resistor beside it (which in itself would not normally change much with temperature- perhaps 100ppm/°C for a metal-film resistor). This old device is pretty low drift (I think max 0.1% for 10°C max overall drift- which is 100ppm/°C) -- they may have tweaked it ...

These seem way too expensive for what they are, but it is the product you asked for: https://www.newark.com/pomona/4115/shorting-bar-for-binding-posts/dp/20H0132

The only ones I've been able to find are here, but looking for 'Shorting Links' and the like doesn't seem to lead to much else.

you know how some transformers are 9-0-9 v transformers, yeah, what's this? It's got a primary winding (red wires) rated at 220 volts and 50 Hz It's got two secondary windings (isolated from each other) of: - 8.2 volts at a full load current of 3 amps (Black wires) 9.2 volts at a full load current of 1.5 amps (Blue wires)
