High-power chips offer far lower thermal resistance than traditional types

18-06-2015 | Stackpole | Passives

The new RHC2512 from Stackpole utilizes novel materials, design, and
processing to offer much lower thermal resistance than other high-power chip
resistors. When used with the recommended solder pad layout, the RHC will
typically show a heat rise of 60C per Watt compared to standard 2512 devices
that can experience more than 120C per Watt, says the company.

In addition to low thermal resistance, the RHC2512 is more stable at higher
power and higher temperatures. This improved stability is demonstrated by
the lower resistance shifts over load life and overload testing. This high
power performance is a popular choice for power electronic and control
applications such as buck converters, HUD systems, IR goggles, HVAC
controls, audio controls, and motor and pump controls.
