What electronic component is abbreviated "RA"?

I saw a circuit board today with a component I haven't seen before and can't find online. It looks like a cross between an IC and a capacitor. It had 8 pins all in one line and there were black ones and red ones.

Resistor array, probably. It's probably 7 resistors with one common pin, or 4 resistors with no common point..

The component is a resistor array. SIP package is used for network with a common node for all resistors. The pin with the red dot is the common pin. Each of the other seven pins is for one resistor. Thus there are total of seven resistors in the array.

That sounds very much like a resistor ceramic pack: several resistors, connected together is some configuration and encapsulated in a ceramic / plastic dip. The internal configuration is often the equivalent of several resistors connected in a star arrangement with their common inter-connect point brought out to one pin; the ends of all the other resistors are individually brought out to separate pins.
All of that is ever so easy to explain in a drawing - but difficult in words - as is so often the case in 'engineering'.
Oh, and yes . . . "RA" . . . 'resistor assembly' . . . . I nearly forgot!
