PDFDatasheet PDF for Fixed Power Resistors.

PDFThe resistance values of resistors follow the E24 series.

Resistors are designed for using in AC and DC circuits, providing current limitation and voltage distribution. 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.

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.

Fixed value resistors have a defined ohmic resistance and are not adjustable.

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%.

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.

Detailed resistor specifications, overall and mounting dimensions, mounting kit, installation and operation recommendations are given on the page below.

Installation methods of tube resistors

At influence of mechanical factors for resistors the hinged way of installation is applied. The resistors are fixed to the mounting plates by mounting hardware:

  • resistor power from 3 to 25 Watt – cantilever or on two brackets at the ends of the mounting studs
  • resistor power from 50 to 160 Watt – only on two brackets at the ends of the mounting studs

Guide for using and operation of resistors:

  • Solder the wires to the resistor leads in specially designed holes.
  • When installing resistors in equipment recommended to use Sn40Pb60 solder. Soldering iron core temperature is 300°C. Soldering iron power is 65W. The flux should consist of 25% by weight of rosin and 75% by weight of isopropyl or ethyl alcohol. Soldering time 5 s.
  • The voltage that can be supplied to the resistor must not exceed the value calculated on the basis of the nominal (or allowable) power Pnom and nominal resistance Rnom according to the formula:
    Vmax = (Pnom × Rnom)0.5
  • Resonant frequency value - 1500 Hz.
  • 95-percent work resource - 30 000 hours.
  • It is allowed to operate resistors under the influence of gas media of this composition (without the formation of an explosive mixture):
    • nitrogen – up to 96%;
    • oxygen – up to 50%;
    • carbon dioxide – up to 3%;
    • hydrogen – up to 20%;
    • helium – up to 1%;
    • argon – up to 1,5%.
  • Operation of resistors during and after exposure to atmospheric pressure reduced to 10~5 mm Hg is allowed.
  • In electrical circuits with voltages above 500V resistors must be used with additional insulation at the mounting points.
  • When using resistors in equipment with vibration loads from 1 to 2500 Hz with an acceleration of 176.6 m/s2 (18g), the resistor leads must be soldered with a 0.5 mm2 wire cross-section with insulation by a polychlorovinyl tube Ø4 mm and length of 15-20 mm – for resistors 5-25 W, and Ø5 mm and length of 15-20 mm – for resistors 50-100 W.
  • Tensile force value should be 20N (2 kgf).
  • The upper frequency of the range in which there should be no resonant frequencies – 1000 Hz.
  • Maximum surface temperature of the resistor is not more than 250°C.

Graph of the resistor power reduction:

The load power should be reduced based on the derating curve once the ambient temperature exceeds the rated values.

I'm Gizem, I'm a chemical engineer. I'm interested in making ceramic stuffs as a hobby. Would you please give some explanation about my questions below;
1) If I only mix SiO2 and Fe2O3 (3:1), can i get a suitable product without using other components?
2) Can i use water as fastener? or would you suggest me another fastener?
3) At which temperature should i mix them?
Thank you for your interest, Kind Regards
Aleksander 26.01.2021 at 14:43
Hello, Gizem. The mass of ceramic is produced by grinding and mixing with water of different components: clay, feldspar, sand, kaolin. The proportions of these materials are different percentages, depending on what and with what characteristics you need to get a ceramic mass.
Each manufacturer of ceramic mass has its own recipes and its own raw materials, which are available in its region.
There are also books on ceramics that specify the chemical composition and approximate recipes for ceramic masses.
