A cement resistor is a type of wirewound resistor that is a relatively high-power resistor that allows a large current to pass.Its function is the same as the general resistance, but it can be used in the case of large current, such as series connection with the motor, limiting the starting current of the motor, and the resistance is generally small.Cement resistors are usually used for high power and high current.There are 2W, 3W, 5W, 10W or even more power.For example, air conditioners, TV sets, etc.which use power above 100W, basically use cement resistance.
Character:
1.Shock resistance, moisture resistance, heat resistance and good heat dissipation, low price and other characteristics.
2. Fully insulated, suitable for printed circuit boards.
3. The wire is wound on the porcelain rod and then welded to the joint to produce accurate resistance value and prolong life.
4. The high resistance value is made by using a metal oxide film body (MO) instead of a winding method.
5. Excellent heat resistance, small temperature coefficient of resistance, a linear change.
6. Short-time overload, low noise, resistance has not changed over the years.
7. The explosion-proof performance is good, play a protective role.

Ho misurato la resistenza di ciascun resistore con un multimetro Proster VC99 (che non sarà un Rohde & Schwarz HMC8012, ma, nella sua fascia di prezzo, funziona bene ...) ottenendo questi valori: 980, 982, 982, 982, 982, 983, 983, 984, 984, 984, 984, 985, 985, 986, 986, 986, 987, 988, 988, 988 Ohm. Nel grafico allegato ne riporto la differenza con il valore di targa 1000 Ohm. La media e' 984.4 Ohm; la varianza è 5.31. Mi sarei aspettato che i valori fossero distribuiti gaussianamente intorno a quello di targa (in soldoni, qualcuno maggiore e qualcuno minore ...) così da poter mettere gli elementi in serie e in parallelo, nel caso mi occorresse una maggiore prossimità al valore teorico. Per la stragrande maggioranza delle applicazioni la circostanza non è fonte del minimo problema (siamo ampiamente entro le tolleranze), ma nel caso qualcuno avesse la necessità di "lavorare più finemente" è bene che ne tenga conto prima di acquistare.
