Wire-wound
Traditional design, consisting of resistance wire wrapped around a ceramic core. Robust, cheap, and with a relatively high element
mass, wire-wound elements provide excellent value due to their ability for withstanding high currents and absorption of large energy
pulses. These resistors are available in a variety of sizes and are suited to applications where high short term overload capacity or very
high power ratings are required.
Suitable Applications: Preferred Product Types:
• Load test simulation C • CFH • CJB • CJS • ER • ES • HS/THS
• Inrush limiting LOAD BANK • R5000 • SBC • SQ • TT/TE • YP
• Crowbar
• Pre-charge
• Capacitor discharge
Thick Film
Thick Film resistive elements consist of a metal and glass films printed onto a flat or tubular ceramic surface. Offering very low
inductance values, these elements can be manufactured with a wide resistance range then laser trimmed to a high degree of accuracy.
Benefits of this technology are the high thermal efficiencies allowing the resistor to have a higher power density compared with
conventional wire-wound elements.
Suitable Applications: Preferred Product Types:
• Balancing resistors BDS • HB • HH • HJ • HVR • MPC • MPT • RGP
• Snubbing
Thin Film
A sputtered film of metal alloy deposited onto a ceramic surface. Commonly used in the manufacturing of precision resistors.
Suited to high specification or technically demanding circuits whilst offering excellent thermal efficiency.
Suitable Applications: Preferred Product Types:
• Inrush limiting MPR • RGP • RR • ROX
• Snubbing
Foil
The element is formed by etching or punching a metal alloy into a serpentine shape which is then enclosed into a resistor package.
This technology has a high element mass enabling it to withstand high energy pulses whilst offering good thermal efficiency and low
inductance. Foil elements offer a robust solution but are limited in resistance value.
Suitable Applications: Preferred Product Types:
• Inrush limiting BDF • R5000
• Snubbing
Carbon Composition / Ceramic Composition
Consisting of either a bulk carbon or ceramic core, this technology is used when protection is required from high energy pulses.
Suitable Applications: Preferred Product Types:
• Inrush limiting CBT • CCR
• Protection
