Mounting Note:
(1) When mounting ensure entire ceramic portion of case is mounted on a clean, flat heat sink with an appropriate
thermal interface, such as thermal grease. For screw mounting use of a compression washer at a force of 150 to
300lbs (665 to 1330N) is recommended without exceeding mounting torque of 8 in-lbs (0.9 N-m) to avoid package
damage. For clip mounting use of a round or smooth clip in contact area is recommended to avoid a concentrated
hot spot on package.
(2) TR50/100 must be mounted to heat sink using proper mounting clip for efficient heat dissipation.

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
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.
