CADKDOC TG931 TG940 TG950 TG980 TG985 TG1010 TG1015
To meet the precision temperature stability requirements of high accuracy, high voltage systems, Caddock introduces the Type TG Low TC Precision High Voltage Resistors.
These resistors utilize our proven Tetrinox® resistance
system to achieve the unique combination of low temperature
coefficient with high stability performance at high operating
voltages.
The Type TG Low TC Precision High Voltage Resistors are designed to meet the demanding stability requirements of TWT power supplies, electron microscopes, X-ray systems, high resolution CRT displays, and geophysical instruments.
Type TG Low TC Precision High Voltage Resistors
All Type TG resistors are produced with Caddock's Non-inductive Serpentine Pattern.
The performance features of the Type TG Low TC Precision High Voltage Resistors are:
• Temperature Coefficient: 25 ppm/°C from -55°C to +125°C.
• Load Life Stability of 0.25% per 1,000 hours at +125°C.
• Resistance Tolerance from ±1.0% to ±0.1%.
• Resistance Range from 1 Megohm to 1,000 Megohms.
• Maximum Continuous Operating Temperature of +225°C.
• The low temperature coefficient minimizes the self-drift due to power dissipation warm-up.

Extended Maximum Continuous Operating Voltage Rating
Maximum continuous operating voltages up to 60% higher than the values listed
in the table can be achieved through special factory conditioning. To specify maximum continuous operating voltages above the values listed in the table, add a "-15" to the model number (Example: TG950-15). Note that the standard overload and overvoltage ratings do not apply to the "-15" resistors. Resistance range for "-15" resistors shown in the table are from "-15 Min." to "Max."
Combine Type TG and Type TK Resistors for Low Ratio TC Tracking
The Type TG Low TC Precision High Voltage Resistors can be
used in combination with the low Absolute Temperature Coefficient of
the Type TK Low TC Precision Radial-Lead Film Resistors
(Model TK133 with TC of 5 ppm/°C) to achieve 30 ppm/°C Ratio
TC without special matching.
With special matching, a Ratio TC of 10 ppm/°C can be achieved.
The low temperature coefficient for both the Type TG
and Type TK resistors will also minimize ratio drift due
to power dissipation warm-up.
Certain products shown in this catalog are covered by one or more patents, there are also patents pending.
