Product Description:
Okuma's E4809-032-470-B resistor is a crucial component of the E4809 CNC Boards family, which are used in OPUS 5000 ECP Card 2 systems.
This resistor finds essential use in CNC systems to provide dependable resistance in electronic control circuits for current regulation and component protection while maintaining stable electrical performance. It delivers reliable operation as it has 470 ohms of resistance and ±10% tolerance, which enables it to work for general-purpose current limiting and voltage division as well as signal conditioning applications. This device maintains operational safety features in power circuits below 0.25W (1/4 watt) that operate typically in control boards and logic-level interfaces. This resistor element shows a temperature coefficient measurement of ±200ppm/°C, which proves its resistance stays stable throughout diverse temperature intervals. The resistor operates at 250V maximum voltage, but still functions safely at overload voltages reaching 500V, which protects against sudden voltage spikes. The ceramic body resistor exhibits both high thermal resistance and electrical-insulating properties because of its material composition for through-hole mounting applications.
The product contains tin-plated copper connections that extend 0.6 mm and deliver outstanding solderability with lengthy resistance to corrosion. The E4809-032-470-B fits into dense circuit boards due to its dimensions of 6.3 mm in length and 2.3 mm in diameter. It also functions well in extremely high working temperatures, with dependable performance for industrial applications between -55°C and +155°C. RoHS regulations, which stand for environmental and safety criteria involving hazardous elements, are met by the equipment. When combined with other parts, this component, which weighs a total of 0.85 lbs (0.39 kg), is essential to ensuring the OPUS 5000 CNC control system operates steadily.
