Pulse rated resistors provide an improvement for design engineers with pulse power requirements
RALEIGH, NC (May 1, 2007) – Stackpole Electronics, Inc. announces
the RPC series of surge withstanding SMD resistors as a better solution
than melf type resistors for applications with pulse requirements. The
RPC series is a thick film SMD chip resistor with improved surge
handling characteristics over standard commercial thick film chips as
well as SMD melf resistor types.
In the past, many design engineers chose SMD melf resistors because of
their relatively low cost and their higher pulse withstanding
capability. For a given resistor footprint, the cylindrical shape of the
melf provides more surface area for resistor as compared to the
equivalent size SMD thick film flat chip. This increased amount of
resistor material leads to better pulse power handling. The RPC series
has no calibration trim, thereby improving the pulse handling
capability. The RPC provides a part that is not only significantly
better than standard resistor chips, but also better than the equivalent
footprint melf resistors. In fact, the RPC pulse performance is
typically between 2 to 5 times better than that of the equivalent size melf.
The RPC is an ideal choice for various types of input or output power /
current limiting requirements. Switch mode power supplies and motor
controls will frequently need this type of current limiting device. The
small size and low price also make it very popular with a variety of
portable electronics including metering and diagnostic equipment,
medical devices, as well as industrial controls, and plasma and LCD
The RPC series is available in sizes 0805 through 2512, in values from
.27 through 22M, and in tolerances as low as 5 %. Packaging is standard
7” tape and reel, 5000 pcs each for 0805 and 1206, and 4000 pcs for the
