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 recom mended without exceeding mounting torque of 8 in-lbs (0.9 N-m) to avoid package

damage. For cl ip m ounting use of a rou nd or sm ooth c lip in c ontact are a is rec omm ended to av oid a c oncentrated

hot spot on package.

(2) TR50/100 must be mounted to heat sink using proper mounting clip for efficient heat dissipation.

“Conf lic t 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.

Complianc e 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. W e are committed to the prevention of all forms

of pollution.
