Wirewound unregulated resistors of type FPT (Fixed Painted Tubular Resistors) series, dissipation power 100W, rated resistance from 3.9 Ohm to 100 kOhm. Similar series of resistors are RX20, RXG, RXHG. Resistors are designed for using in AC and DC circuits, providing current limitation and voltage distribution. Resistors with a specific rated power can also be manufactured to individual order.
Structurally, the resistor consists of a tubular ceramic core on which a constantan (low resistance resistor) or nichrome (high resistance resistor) wire is wound. Resistors are coated with heat-resistant and moisture-resistant insulating paint.
Contacts, resistor leads are rigid, tape type with screw holes or for soldering conductors. Kind of mounting is hinged. Mounting of resistors on the panel is provided by a set of fasteners. Resistance tolerance is ±5%, ±10%.
The maximum operating voltage at AC is 1000V, at DC – 1400V. Operating elevated ambient temperature does not exceed +155°C (at the same time the power is reduced to 60% of the nominal power), the limit temperature up to +250°C. The insulation resistance of wire resistors is at least 1000 MOhm. Working time – at least 15000 hours.
Using the calculator, it is convenient to calculate the total resistance when the resistors are connected in parallel or in series, and the resistor resistance in the circuit.
Comparative characteristics of wire tube resistors, cement resistors and resistors in aluminium housing are presented in the comparative table.
