Repetitive Pulse Information:
If repetitive pulses are applied to resistors, pulse wave form must be less than “pulse limiting voltage”, “pulse limiting
current” or “pulse limiting wattage” calculated by the formula below.

lp = K√P/R x T/t
Pp = K2 x P x T/t

If T > 10 → T = 10 (sec), T / t > 1000 → T / t = 1000
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), decrease power rating according to
“Power Derating Curve”
Assure sufficient margin for use period and conditions for “pulse limiting voltage”
If the pulse waveform is not square wave, judge after transform the waveform into square
wave according to the “Waveform Transformation to Square Wave”.

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
