AEP Components Products

HVR High Voltage, Non Inductive, Ceramic Carbon Linear Resistors are manufactured (to ISO 9001-2000 Standards) from a carefully blended mixture of clays, alumina and carbon.

After mixing and granulating, the material is pressed to the required shape, with diameters ranging from 3 to 152mm.

The resistors are then fired, at very high temperatures, in a tunnel kiln with a controlled reducing atmosphere. This produces a Bulk Ceramic Carbon Resistor which is 100% Active Material, and therefore of Minimum Size.

Typically aluminium is then flame sprayed onto the flat surfaces of the Ceramic Resistor to provide reliable electrical contact and an anti-track coating is applied to the edges to improve dielectric withstand.

The Ceramic Carbon Resistor Technology enables the manufacture of a Wide Variety of Geometries in a Wide Resistivity Range, with constant mechanical strength. They are Robust, good in compression and capable of absorbing transmitted mechanical shock, provided direct impact is avoided.

Linear Disc

HVR Linear Disc Resistors are manufactured from a carefully blended mixture of clays, alumina and carbon. After blending, the material is pressed to the required shape, with diameters ranging from 3 to 150mm. The Resistors are then fired at high temperature in a tunnel kiln with controlled atmosphere. This produces a Ceramic Carbon Resistor which is 100% active material and therefore of minimum size. Aluminium is then flame-sprayed onto the flat surfaces of the resistor to provide electrical contact, and an anti-track coating is applied to the periphery to improve dielectric withstand. With the capability of sustaining energies ranging from Joules to Mega-Joules, at frequencies up to Mega-Hz, HVR Linear Disc Resistors can be used in even the most demanding applications such as electrical transmission, traction, AC/DC drives, pulse power, dummy loads, induction heating and pulse forming networks.

SR Surge

The SR Series of Surge Resistors for PCB mounting are manufactured from a carefully selected mixture of clays, alumina and carbon. After blending, the material is pressed to the required shape and then fired, in a controlled atmosphere, at high temperature. This sintering process produces a Ceramic Carbon Resistor which is 100% active material and therefore of minimum size. The SR Series feature Gold Plated Brass spring pin terminations for ease of assembly into Printed Circuit Boards (PCB’s). Dielectric withstand and mechanical robustness are enhanced by the UL94 V-0 approved epoxy resin coating. Compact in size and with high surge energy rating, the modular SR Series is designed to provide the optimum solution to many Power Electronics applications; notably soft starting the DC link capacitors in Switch Mode Power Supplies. Inherently non-inductive and capable of withstanding transient high voltage impulses, the SR Series is similarly effective with respect to overvoltage protection and crowbar discharge applications.

H.V. Compact Series

HVR’s range of High Voltage Resistors for Compact Circuitry are manufactured from a carefully selected mixture of clays, alumina and carbon. After blending, the material is pressed to the required shape and then fired, in a controlled atmosphere, at high temperature. This sintering process produces a Ceramic Carbon resistor which is 100% active material and therefore of minimum size.¬†The H.V. Resistors¬† for Compact Circuitry range feature radial lead terminations and a high quality epoxy resin coating to improve both dielectric withstand and mechanical robustness. Inherently non-inductive and capable of withstanding transient high voltage impulses, this range is ideally suited to charging, discharge, snubber, voltage divider and overvoltage protection applications. These typical applications feature within high voltage power supplies, lasers, radar, medical and military equipment.
