CSR/CSRN Series
Thick Film Current Sensing Resistor
Stackpole Electronics, Inc.
Resistive Product Solutions
High Power Chip Resistors and Thermal Management
Stackpole has developed several surface mount resistor series in addition to our current sense resistors, which have had
higher power ratings than standard resistor chips. This has caused some uncertainty and even confusion by users as to
how to reliably use these resistors at the higher power ratings in their designs.
The data sheets for the RHC, RMCP, RNCP, CSR, CSRN, CSRF, CSS, and CSSH state that the rated power assumes
an ambient temperature of no more than 100°C for the CSS / CSSH series and 70°C for all other high power resistor
series. In addition, IPC and UL best practices dictate that the combined temperature on any resistor due to power
dissipated and ambient air shall be no more than 105°C. At first glance this wouldn’t seem too difficult, however the graph
below shows typical heat rise for the CSR ½ 100 milliohm at full rated power. The heat rise for the RMCP and RNCP
would be similar. The RHC with its unique materials, design, and processes would have less heat rise and therefore
would be easier to implement for any given customer.
The 102°C heat rise shown here would indicate there will be additional thermal reduction techniques needed to keep this
part under 105°C total hot spot temperature if this part is to be used at 0.75 watts of power. However, this same part at
the usual power rating for this size would have a heat rise of around 72°C. This additional heat rise may be dealt with
using wider conductor traces, larger solder pads and land patterns under the solder mask, heavier copper in the
conductors, via through PCB, air movement, and heat sinks, among many other techniques. Because of the variety of
methods customers can use to lower the effective heat rise of the circuit, resistor manufacturers simply specify power
ratings with the limitations on ambient air temperature and total hot spot temperatures and leave the details of how to best
accomplish this to the design engineers. Design guidelines for products in various market segments can vary widely so
it would be unnecessarily constraining for a resistor manufacturer to recommend the use of any of these methods over
another.
Note: The final resistance value can be affected by the board layout and assembly process, especially the size of the
mounting pads and the amount of solder used. This is especially notable for resistance values 50mΩ.
This should be taken into account when designing.

RoHS Compliance
Stackpole Electronics has joined the worldwide effort to reduce the amount of lead in electronic components and to meet the various
regulatory requirements now prevalent, such as the European Union’s directive regarding “Restrictions on Hazardous Substances”
(RoHS 3). As part of this ongoing program, we periodically update this document with the status regarding the availability of our
compliant components. All our standard part numbers are compliant to EU Directive 2011/65/EU of the European Parliament as
amended by Directive (EU) 2015/863/EU as regards the list of restricted substances.
“Conflict Metals” Commitment
We at Stackpole Electronics, Inc. are joined with our industry in opposing the use of metals mined in the “conflict region” of the eastern
Democratic Republic of the Congo (DRC) in our products. Recognizing that the supply chain for metals used in the electronics industry
is very complex, we work closely with our own suppliers to verify to the extent possible that the materials and products we supply do
not contain metals sourced from this conflict region. As such, we are in compliance with the requirements of Dodd-Frank Act regarding
Conflict Minerals.
Compliance to “REACH”
We certify that all passive components supplied by Stackpole Electronics, Inc. are SVHC (Substances of Very High Concern) free and
compliant with the requirements of EU Directive 1907/2006/EC, “The Registration, Evaluation, Authorization and Restriction of
Chemicals”, otherwise referred to as REACH. Contact us for complete list of REACH Substance Candidate List.
Environmental Policy
It is the policy of Stackpole Electronics, Inc. (SEI) to protect the environment in all localities in which we operate. We continually strive
to improve our effect on the environment. We observe all applicable laws and regulations regarding the protection of our environment
and all requests related to the environment to which we have agreed. We are committed to the prevention of all forms of pollution.
