A jumper chip component is designed to be mounted onto a printed board. The jumper chip component includes a base, a conductor, and an end face electrode. The base has electrical insulation properties. The conductor is disposed on a lower surface, facing the printed board, of the base to extend from a first end of the lower surface through a second end, facing the first end, of the lower surface. The end face electrode is disposed on at least a side surface of the base and arranged to be electrically connected to the conductor.

A voltage divider circuit assembly includes resistors, an external electrostatic shield, and internal electrostatic shield(s). The resistors are in series with each other between input terminals that receive an input voltage. An external resistor is disposed between sensing terminals that conduct an output voltage that is the input voltage divided by the resistors in the series. The external shield is conductively coupled with the series of the resistors with the external resistor disposed outside of the external shield and the other resistor(s) inside the external shield. The internal shield(s) are conductively coupled with the resistors and disposed inside the external shield. A first internal resistor is disposed inside the external shield and outside of the internal shield(s). One or more remaining resistors are inside the internal shield(s). The shields divide parasitic capacitances to enable the measurement of dynamically changing high voltage input signals.
