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.
Vp = K√P x R x T/t
lp = K√P/R x T/t
Pp = K2 x P x T/t
Where: Vp:

Coefficient: 0.8
Rated Voltage (V), Ir: Rated Current (A)]
Note 1: If T > 10 → T = 10 (sec.), T / t > 1000 → T / t = 1000.
Note 2: If T > 10 and T / t > 1000, “Pulse Limiting power (single pulse) is applied.
Note 3: If Vp < Vr (lp < lr or Pp < P), Vr (lr, P) is Vp (lp, Pp).
Note 4: 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”.
Note 5: Please assure sufficient margin for use period and conditions for “Pulse limiting voltage”.
Note 6: If the pulse waveform is not square wave, please judge after transform the waveform into square
wave according to the “Waveform Transformation to Square Wave”.

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 26 mm 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 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.
