Tubular Non-Inductive High Voltage Precision Divider Resistors (HI80M)
DeMint Electronics is further expanding its solutions for challenging applications and introducing thick-film precision resistor dividers for high-voltage measurement circuits. The new (HI80M) was introduced to meet the growing demand in the medical, energy, industrial and instrumentation markets.
Thick film technology allows high resistance values to be printed on flat or cylindrical substrates. Not only can high resistance be obtained, but a high voltage can be applied to the thick film product with almost no change in resistance value. Many thick film resistors are printed using a serpentine pattern. This pattern helps reduce inductance and is the first choice for stable frequency applications.
As new industries expand, so does the demand for such components. Applications such as portable defibrillators, high-voltage PSUs, on-board instruments, TWT power supplies, radar systems, X-ray systems, analytical equipment, and high resolution CRT displays require components with tight tolerances, leading temperature coefficient (TCR), load life stability and extremely high impedance values to provide optimum space, weight and cost combinations. Package.
The Cylindrical (HI80M) of high quality, high voltage, versatile, non-inductive, thick film precision dividers available from DeMint Electronics. The (HI80M) divider features with voltage handling capability of up to 80 KVdc and has an operating temperature range of -55°C to +125°C, wide resistance range 2MΩ to 1GΩ with Resistive Ratio R2/(R1+R2) 1:1000 to 1:20000, and power up to 41W.
The (HI80M) conforms to the RoHS directives and Lead-free. To assist with your specifying high voltage divider application, please contact DeMint Electronics. We can offer high voltage divider combinations and solutions based on high voltage resistor sector in the catalog, or use our sophisticated features to provide higher accuracy in matching resistor sets. Customed design, and tighter tolerances are available on request.
