Dimension "E":
This is a non-critical dimension that does not have a tolerance in the standard.
Range of diameters is from 0.547 inches (13.90 mm) to 1.500 inches (38.10 mm).
(1) Reference value only. The "A" dimension shall be governed by the overall length of the taped component.
The distance between flanges shall be 0.059 inches (1.50 mm) to 0.315 (8.00 mm) greater than the overall component.
(2) The given dimension "D" expresses the standard width spacing. A 26mm narrow spacing is available as option "N" packaging code.

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 2). 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.

“Conflict Metals” Commitment
Stackpole Electronics, Inc.
Resistive Product Solutions
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.
