| An expensive product that's probably just one component in a box......... |

It is not your grandfa's axial resistor in the 50 Ohm cal standard. Also, try disassembling an industrial cal standard and let us know how easy it was. |

I remember one: Was looking at a faulty manifold pressure sensor in a racing plane and why it failed. Opened it and found that it's basically a through hole part from ST in a milled little box (4-wire - power supply and diff out). The part cost was 10€, but since the sensor was FAA certified, the sensor costs some ~300-400€. Go figure... Maybe I'm in the wrong business :) To be fair, certification is kinda expensive. EDIT: Found the sensor. It seems the price went down a little. https://www.aircraftspruce.com/catalog/inpages/jpimanifoldpresssense.php |

And one of the parts must have had an aerospace connector on it right? |

On a FAA cert part in an acrobatic/racing plane. I thought it was a joke. |
