7 Please confirm technical specifications before you order and/or use. CF / CFM Series Carbon Film Resistor Stackpole Electronics, Inc. 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. 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: [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.

8 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 .
