Repetitive Pulse Information
(This information is for reference only and is not guaranteed performance.)
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.
Where: Vp: Pulse limiting voltage (V)
lp: Pulse limiting current (A)
Pp: Pulse limiting wattage (W)
P: Power rating (W)
R: Nominal resistance (ohm)
T: Repetitive period (sec)
t: Pulse duration (sec)
K: Coefficient by resistors type (refer to below matrix)
[Vr: 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”.

Part Marking Specifications
The thermal resistance of the RMCP will be similar to the RMCF. For example, the RMCF2512 and the RMCP2512 will have similar
surface temperatures at 1W; the RMCP is designed to withstand higher temperatures associated with high power levels.
A two-digit number is assigned to each standard R-Value (E96) as shown in the chart below.
This is followed by one alpha character which is used as a multiplier. Each letter “Y” – “F” represents a specific
multiplier as follows:
For shared E24/E96 values, 1% tolerance product may be marked with three digit marking instead of the standard four digit
marking for all other E96 values. All E24 values available in 1% tolerance are also marked with three digit marking.
5% Marking
The nominal resistance is marked on
the surface of the overcoating with the
use of 3 digit markings.
0201 and 0402 are not marked.
1% Marking
The nominal resistance is marked on
the surface of the overcoating with the
use of 4 digit markings.
0201 and 0402 are not marked.

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.
