CF/CFM Series Stackpole Electronics, Inc. Carbon Film Resistor Resistive Product Solutions Repetitive Pulse Data: 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: 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”.
