CORPUS CHRISTI, TX (March 2007) – Providing power electronics engineers with more options in resistive devices that meet new power supply and voltage requirements, TT electronics IRC Advanced Film Division has extended the resistance range and voltage rating of their high power dissipation surface mount chip resistors. The SC-3 series resistors now feature resistance values up to 100K ( and voltage ratings to 100V.
According to Gary Bleasdell, thick film business unit director for IRC's Advanced Film Division, there has been an increasing demand from customers for the higher specifications. “Previously, the resistance range only went to 200O and the voltage rating to 50V, limiting customers in the use of this device,” said Bleasdell. “The extended ranges allow customers to replace more expensive and bulky molded wirewound devices in motor and laser drive circuits, inverters, medical electronics and automotive applications.”
Additional applications for the SC-3 Series resistor include power supply bleeders, series voltage drop resistors, pulse applications, and voltage dividers. The SC-3 Series chip resistors feature resistance ranges from 1 to 100K, with a maximum voltage rating of 100V and absolute tolerance to ±1%. The resistor dissipates to 3W @ 70° C and features a TCR of ±100ppm/° C. The operating temperature range is from -55° C to +150° C. The chip resistors feature leach-resistant 60/40 tin/lead or 100% matte tin over nickel plated wrap-around terminations. IRC will also produce devices outside these specifications to meet customer requirements.
