RNF / RNMF Series Stackpole Electronics, Inc. General Purpose Metal Film Resistor Resistive Product Solutions 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: 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: RNF / RNMF Coefficient: 0.7 [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), decrease power rating according to “Power Derating Curve” Note 5: Assure sufficient margin for use period and conditions for “pulse limiting voltage” Note 6: If the pulse waveform is not square wave, judge after transform the waveform into square wave according to the “Waveform Transformation to Square Wave”. Waveform Transformation to Square Wave 1. Discharge curve wave with time constant “t” → Square wave 2. Damping oscillation wave with time constant of envelope “t” → Square wave Rev Date: 08/24/2020 3 www.seielect.com This specification may be changed at any time without prior notice marketing@seielect.com Please confirm technical specifications before you order and/or use.

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.
