Stackpole’s 2W 2512 Resistors Exhibit Improved Thermal Characteristics

\[October 3, 2003\] The RHC series of thick-film, high-power chip resistors can dissipate 2W in a 2512-size SMD package. Its unique design and specialized materials and processes yield a component that typically runs 30°C cooler than standard 2512 chips and has solder joint temperatures well below the industry standard of 105°C for circuit boards. Also, the maximum 5s overload power is 70% higher than standard 2512 chips, and the devices show no additional resistance shift for the EIA 575 standard short-time overload test at the elevated power rating. E24 values from 0.1Ω to 1 MΩ are available, with a continuous working voltage of 200V. The RHC series is RoHS-compliant and is available in 4000-piece tape-and-reel configuration, with samples available in three to four weeks. The resistors cost $0.12 each for 5% tolerance and $0.18 each for 1% tolerance. STACKPOLE ELECTRONICS INC., Raleigh, NC. (919) 850-9500.
