New ruthenium material, extended ultra-precision high-power high-voltage resistors (HI80) breakthrough 300W, precision narrowed to 0.1%.

DeMint electronic ultra-precision high-power high-voltage resistor (HI80) family series take advantage of new ultra-fine ruthenium material, 95% aluminum oxide ceramic rods, and thick film non-inductive Serpentine Pattern Design. Precision can be narrowed to ±0.1%, and power breakthrough 300W. (HI80) featuring heat-resistant, humidity-resistant, resisting electrical pulse, and stable and reliable long-term performance, is specifically designed for general purpose industrial high voltage system applications.

(HI80) family of high-voltage resistors includes conventional high-voltage resistors (HI80D), conventional miniaturized high-voltage resistors (HI80DS), high-power high-voltage resistors (HI80P), and ultra-precision high-voltage resistors (HI80T).

Conventional high voltage resistors (HI80D) have a wide resistance range of 200Ω ~ 10GΩ, rated power 2.5W ~ 20W, accuracy tolerance F (± 1%), J (± 5%), K (± 10%), the lowest temperature coefficient down to 50ppm on request, and the standard temperature coefficient of 100ppm.

(HI80DS) All-film conventional miniature high-voltage resistor relative to (hi80d), with small size, higher power 3W ~ 30W, withstand higher voltage, and none-inductance. The temperature coefficient of the lowest can reach 50ppm (25°c ~105°c), the standard temperature coefficient of 100ppm. Precision Tolerances F (±1%), J (±5%), K (±10%).

High power high voltage resistors (HI80P) have high rated power 20W ~ 300W, resistance range 1Ω ~ 1GΩ, precision tolerance D (± 0.5%), F (± 1%), J (± 5%), K (± 10% ), The temperature coefficient of up to 25ppm (on request), the standard temperature coefficient of 50ppm.

Ultra-precision high-voltage resistor (HI80T) characters 15ppm temperature coefficient, the standard temperature coefficient is 25ppm, the precision tolerance has B (± 0.1%), D (± 0.5%), F (± 1%), the resistance range 1Ω ~ 500MΩ, and the rated power 0.8W ~ 6W to choose from.

DeMint (HI80) Voltage Resistor series is able to absorb large amounts of energy at high voltage while remaining non-inductive and heavy load characteristics. The HI80 conforms to the RoHS directives and Lead-free. Customed design, and tighter tolerances are available on request.
