BR Series

Bare Element Current Sense Resistor

Stackpole Electronics, Inc.

Resistive Product Solutions

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.
