High Voltage Thick Film Dividers (HI83)

Thick Film Planar Dividers, Through-Hole, High Voltage Resistors (HI83)

Through-hole (HI83) thick film planar divider, high voltage resistor series is a new generation of Direct Electronic Technology Co., Ltd. Taking advantage of high-quality ruthenium oxide resistance material to 96% alumina planar ceramic matrix, dividers (HI83) features good thermal conductivity, small size, and high reliability. Custom dividers available with leadwire terminals or with leadless conductive pads.

The planar thick film divider resistor (HI83) provides stable performance over a wide range of resistance values with a voltage rating up to 35KV. The maximum resistance ratio is 1000: 1 (ratio greater than 1000: 1, such as 2000: 1, 4000: 1, and 5000: 1 is available on request) with a minimum resistance ratio of 40: 1.

Low temperature coefficient can be used for high stability circuit applications. Space-saving planar packages provide an alternative to traditional high-voltage resistors. (HI83) is mainly used in precision instruments, drive circuits, power supplies, transformers, high voltage power equipment, and any need to operate in high voltage electrical appliances and other fields.

The main structure of the planar thick film voltage divider (HI83): The terminal connecting conductor and the ruthenium oxide resistive material were printed on the surface of the 96% alumina substrate in a non-inductive pattern. Then apply the screen printing protection, after connect the terminals. Phosphor bronze solder is welded to the lead frame terminal and is immersed in SnAgCu to meet the following IEC weldability requirements.

Thick film (HI83) voltage dividers are RoHS compliant and 100% lead free. For conventional parameters, specifications outside the parameters, or technical requirements, please contact Direct.
