Axial Leaded High Voltage Ceramic Resistors

100 & 200 Series Axial Leaded Non-Inductive Bulk Ceramic Resistors provide excellent performance where high peak power or high-energy pulses must be handled in a small size. The advantage of the bulk construction is that it produces an inherently noninductive resistor; and it allows energy and power to be uniformly distributed through the entire ceramic resistor body — there is no film or wire to fail. We offer a full line of rugged, reliable ceramic resistors — including custom designs. Three distinctly different ceramic materials are available in each size to afford the designer with unique components to meet the most demanding requirements. As alternatives to hard to find carbon composition resistors, composition resistors can be used as drop-in replacements for 1 and 2 watt sizes. Much larger sizes, up to 70 watts in a single component, are available for new or re-designs where an array of smaller resistors may have been previously required.

Features:

  • Replacement of Carbon Composition Resistors
  • Large peak energy in small size
  • High power dissipation (Type SP)
  • High voltage and energy absorption (Type AS)

1. @ 40°C Ambient. Derate linearly to 0 Watts at 230°C for Type AS and BA. Derate linearly to 0 Watts at 350 °C for Type SP.

2. Allowable peak energy/voltage will depend on the resistance value and pulse width. Energy ratings are based on pulse <10 milliseconds. Type SP rating can be substantially greater for longer pulses. Consult factory.

3. Peak Current Ratings presume energy approaching rated peak energy values. Allowable current can be higher for lower energy values. Consult factory.

4. Excludes caps/leads and coating.
