CSRF Series Foil on Ceramic Current Sensing Chip Resistor Stackpole Electronics, Inc. Resistive Product Solutions Soldering Recommendations:

  • Peak reflow temperatures and durations: o IR Reflow Peak = 260°C max for 10 seconds o Wave Solder = 260°C max for 10 seconds
  • Compatible with lead and lead-free solder reflow process
  • Recommended IR Reflow Profile: 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 ºC for the CSS / CSSH series and 70 ºC 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 105ºC. At first glance this wouldn’t seem too difficult, however the graph below shows typical heat rise for the CSR1206 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.

CSRF Series Foil on Ceramic Current Sensing Chip Resistor Stackpole Electronics, Inc. Resistive Product Solutions The 102ºC heat rise shown here would indicate there will be additional thermal reduction techniques needed to keep this part under 105 ºC 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 woul d have a heat rise of around 72 ºC. This additional heat rise may be dealt with using wider conductor traces, larger solder pads and land patterns under th e solder mask, heavier copper in the conductors, vias 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 simpl y 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 wi th the status regarding the availability of our compliant components. All our standard part numbers are compliant to EU Directive 2011/65/EU of t he 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 s upply 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.
