Apparatus and a method of installing feed through capacitors for automotive radio frequency suppression applications, in which a number of the capacitors are employed, each interposed between a power supply terminal and an electrically powered device. The method includes the step of assembling the capacitor components to an insulated wire, which is of the required length to extend from the power supply terminal to the powered device, eliminating the need for separately connected leads to and from the capacitor. Also included is a contact disc clip retainer crimped to the insulated wire to anchor the capacitor components thereto. The capacitor windings are also received over the insulated wire and positioned with one end face in abutment against the contact disc clip retainer disposed within a metallic capacitor housing. A D-clip engages the opposite face of the capacitor windings and in turn engages the interior metallic fastener housing which is grounded. The invention is particularly adapted to installations requiring a number of varying lead lengths, such that a number of different lengths of insulated wire are employed.

An EEPROM constructed in accordance with our invention includes a voltage multiplier for generating an erase voltage and a voltage regulator circuit for controlling the magnitude of the erase voltage. The voltage regulator circuit includes means for providing a first voltage proportional to the erase voltage, means for providing a reference voltage on a reference voltage lead, and means for controlling the voltage multiplier circuit so that if the first voltage is less than the reference voltage, the voltage multiplier circuit will increase the erase voltage, but if the first voltage is greater than the reference voltage, the voltage multiplier will not continue to increase the erase voltage. The voltage multiplier includes novel capacitors and transistors constructed using standard EEPROM processing to withstand high voltages without breaking down.

An EHT power supply, for example for a cathode ray tube, having a voltage multiplier of a multi-stage Cockroft-Walton type, in which the capacitors of each stage are formed by layers of conducting material juxtaposed on either side of a layer of dielectric material, the layers of dielectric material forming an integral part of the mechanical structure of the multiplier and physically supporting the rectifier diodes of the multiplier. In one embodiment of the invention, the multiplier is formed as a closely-spaced stack in which each stage comprises a separate layer of dielectric material, and in another embodiment the capacitors of the AC side of the multiplier are formed on one layer of material and the capacitors of the DC side of the multiplier are formed on another layer, the two layers being disposable on opposite sides of the neck of a cathode ray tube with the successive stages being longitudinally disposed along the neck.

A high-voltage device having a measuring resistor, also called a bleeder, is plunged into an electrical field whose voltage varies in the same way as the voltage along the bleeder. To achieve this, the capacitive elements are distributed in two rows, each row defining a plane. Along each row, the potentials are growing. The space between the two rows is sufficient for the bleeder to be placed therein. The bleeder is formed either by series-connected resistors or by a screen-printed resistor.
