X-1r m i-h eg m Ultra High Resistance High Stability Hermetically Sealed features applications These Hi-Meg resistors are designed for use in electrometer circuits Glass sealed hermetric resistors Ultra high vacuum where a high order of performance Improved temperature stability Medical instrumentation is required. These resistors achieve Improved voltage stability Current pulse limiters a high degree of accuracy and stability, and operate at this high Metal oxide resistive elements Avionics performance level for an extended No outgassing period of time. By being vacuum RoHS compliant sealed in a glass envelope, these Hi-Megs are suitable for ultra-high Calibration available vacuum applications. characteristics Handling and Cleaning of RX-1M Resistors: Resistance 1M to Range 10,000,000M These glass encapsulated resistors, especially 0.5W at 25C those of higher resistance value, require extraor- Power Rating dinary cleanliness. These resistors should be Voltage Rating 1.0KV handled by the terminals, unless gloves are worn. Temperature as low as Fingerprints on the surface of the resistor will Coefficient 50PPM/C attract contaminants and moisture, which will cause a parallel resistance path, reducing the resistance value of the device. If cleaning should become necessary, use isopropyl alcohol and light- ly wipe dry with lint free tissues such as Kimwipes. dimensions 0.9 / 0.9 / 22.9 mm 22.9 mm min. min. 1.875 /47.63 mm max. 0.198 /5.0 mm 0.025 .002 dia. max. 0.64 mm ordering information RoHS RX-1M1006F E Compliant Tolerance Hi-Meg Ohms D= 0.5% Series First 3 digits are F= 1% significant 4th digit is G= 2% multiplier ( of zeroes J= 5% to follow).
