Ohmite 100 & 200 Series Bulk Ceramic Axial Lead Resistors

Ohmite 100 and 200 Series Bulk Ceramic Axial Lead Resistors perform excellently where high peak power or high-energy pulses must be handled in a small size. These resistors feature bulk construction, high power dissipation, large peak energy in small size, and uniform energy distribution throughout the resistor body. The bulk construction produces an inherently non-inductive resistor allowing energy and power to be uniformly distributed through the entire body of the ceramic resistor.

The Ohmite 100 and 200 series axial lead resistors are built using three distinctly different ceramic materials to meet the most demanding requirements. The Type SP lead resistors can withstand high operating temperatures resulting in high power dissipation. These resistors are suitable for use in oil without an oil-resistant coating. The Type AS lead resistors feature a maximum continuous operating temperature of +230°C and are suitable for high energy and voltage pulse applications. These resistors must have a standard dielectric coating while using in air and oil-resistant coating while using in oil. The Type SP and Type AS resistors are ideal for use in RC snubber circuits, spark-gap limiters, pulse waveform, RF dummy load circuits, and capacitor dump circuits.

The Type BA resistors are suitable for high energy and voltage pulse applications where the required resistance value is above Type SP and AS resistors' values. These resistors feature a maximum continuous operating temperature of +230°C. The Type BA resistors require a standard dielectric coating for use in air and an oil-resistant coating for use in oil. Typical applications include voltage balancing, voltage divider, filter, snubber, crowbar, measuring, and test loads.
