If T > 10 and T / t > 1000, “Pulse Limiting power (Single pulse) is applied.
If Vp < Vr (lp < lr or Pp < P), Vr (lr, P) is Vp (lp, Pp).
Pulse limiting voltage (Current, Wattage) is applied at less than rated ambient temperature. If ambient
temperature is more than the rated temperature (70°C), please decrease power rating according to “Power
Derating Curve”.
Please assure sufficient margin for use period and conditions for “Pulse limiting voltage”.
If the pulse waveform is not square wave, please judge after transform the waveform into square wave
according to “Waveform Transformation to Square Wave” information.

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 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 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 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.
