I don't know who actually makes them but I wish they'd stop: I've had plenty of these fail in recent years. Some are useless-from-new: I had a bandolier of 330pF ones where both the wires were connected to the same foil !
Yes it was. I don't know the manufacturer, but never had a problem with them before. I used to think that silver mica types were practically blameless, but have had to replace one some while back. The interesting thing about this was that it measured correctly on the bridge, but I think there must have been a bit of variable leakage which was dependent upon the applied pressure.
