MR / MRS / TMR Series Low Resistance Value Resistor – Molded 2 and 4 Leads Stackpole Electronics, Inc. Resistive Product Solutions RoHS Compliance Stackpole Electronics has joined the worldwide effort to reduce the amount of lead in electronic components and to meet the v arious regulatory requirements now prevalent, such as the European Union’s directive regarding “Restrictions on Hazardous Substance s” (RoHS 3). As part of this ongoing program, we periodically update this document with the status regarding the availability o f our compliant components. All our standard part numbers are compliant to EU Directive 2011/65/EU of the European Parliament a s 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 ex tent 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. Packaging Specifications RoHS Compliance Status (1) (2) The given dimension "D" expresses the standard width spacing. A 26 mm narrow spacing is available as option "N" packaging code. Dimension "E": This is a non-critical dimension that does not have a tolerance in the standard. Reference value only. The "A" dimension shall be governed by the overall length of the taped component.
