The SQ series resistors are wound or deposited on a fine non - alkali ceramic core then embodied in a ceramic case and sealed with an inorganic silica filler. This design provides a resistor with high insulation resistance, low surface temperature, excellent TCR, and entirely fire proof construction. These resistors are ideally suited to a range of areas where low cost, and efficient thermal performance are important design criteria. Metal film cores adjusted by laser spiral are used where the resistor value is above that suited to wire. Similar performance is obtained although short time overload is slightly derated.

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: • Load test simulation • Inrush limiting • Crowbar • Pre-charge • Capacitor discharge Preferred Product Types: C • CFH • CJB • CJS • ER • ES • HS/THS LOAD BANK • R5000 • SBC • SQ • TT/TE • YP 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: • Balancing resistors • Snubbing Preferred Product Types: BDS • HB • HH • HJ • HVR • MPC • MPT • RGP 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: • Inrush limiting • Snubbing Preferred Product Types: MPR • RGP • RR • ROX 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: • Inrush limiting • Snubbing Preferred Product Types: BDF • R5000 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: • Inrush limiting • Protection Preferred Product Types: CBT • CCR 36 Literature No. 4-1773460-6 Issued 3-11 Dimensions are in millimeters and inches unless otherwise specified.

The resistor limits the inrush current during charging of the DC coupling capacitor. This capacitor sits across the DC voltage source to keep the line voltage constant when the input voltage drops low. The resistor must be able to absorb high energy from a single pulse, over a short time. • Key Feature: Short-term overload capability Capacitor Discharge Resistor The resistor is fitted across the capacitor terminals to provide a safety function. When the voltage to the capacitor is removed, the resistor discharges any residual voltage in the capacitor making it safe to touch. The resistor must handle continuous power as it dissipates power continuously when the capacitor is connected to a voltage source. • Key Feature: Continuous power dissipation Inrush Limiting Resistor Similar to precharge resistor, but offers protection to the rectifier section of circuit. • Key Feature: Short-term overload capability Crowbar Resistor The resistor is used to drop the voltage to earth safely, generating a zero voltage in the circuit when a fault has been detected. • Key Feature: Ability to absorb large short-term energy and voltage overloads, with a high insulation resistance Balancing Resistor The resistor is used to balance the voltage across critical components (such as IGBTs) when they are connected in series. This is to ensure that each component has equal voltage stress during operation. • Key Feature: Tight tolerance, low power and high ohmic value Current Sense Resistor A low ohmic resistor creates a small voltage drop in the circuit. As the current in the circuit changes the voltage drop will vary. The change in voltage drop is used to measure the current to or from the circuit. This current can be monitored allowing an action in the control software. • Key Feature: Low ohmic value, high accuracy Snubber Resistor The resistor is used to absorb transient high voltage spikes produced by switching a solid state switch (like relays, IGBTs, GTOs, etc.). It is connected in series with a capacitor across the switch. These switching operations can be very high frequency therefore the resistor must have a low inductance, so that the transient spike is not transferred back into the switch. • Key Feature: Dissipation of repetitive energy pulses, low inductance Filter Resistor This resistor makes up a RC network which is used to reduce the noise on power lines. The resistor is fitted inline with a capacitor with one side connected to earth enabling it bleed overvoltage to ground. These resistors must be able to handle continuous power as they are in circuit constantly as the frequency of noise is high enough to be considered constant. • Key Feature: Continuous power dissipation Note: Partial Discharge A resistor with low partial discharge is a requirement of many of the applications above. Partial discharge is a form of high voltage test that can be used to measure the life of the component. It measures the amount and size of voids in the insulation and therefore the quality of it. 37 Literature No. 4-1773460-6 Issued 3-11 Dimensions are in millimeters and inches unless otherwise specified.
