FSP150KB-39R

Through-hole resistors Circuit Breaker & Axial Lead Type Fiberglass Cement Resistors Normal Style [ FSP Series ] FEATURES Power Rating 1.2W, 1.5W, 2W, 2.5W, 3W, 4W, 6W Resistance Tolerance ±5%, ±10% T.C.R. -80~+500ppm/°C DERATING CURVE TEMPERATURE RISE INTRODUCTION 150 The FSP Series Fiberglass Cement Resistors are wound on fibre glass core, have a special internal direct contact to virtually eliminate resistance changes caused by varying, often high temperatures. It offers a circuit-breaker function when overload is applied. 25 120 150 250 200 300 400 600 150 °C Temperature Rise Rated Load (%) 100 80 60 40 20 100 50 (°C) 20 40 60 80 0 100 120 140 160 2 4 6 8 10 12 14 Power Rating Ambient Temperature (°C) DIMENSIONS 16 [W] Unit: mm +0,2 2 10,000M Solderability IEC 60115-1 4.17 245±5°C for 3±0.5 Sec. 95% Min. coverage Solvent Resistance of Marking IEC 60115-1 4.30 IPA for 5±0.5 Min. with ultrasonic No deterioration of coatings and markings Robustness of Terminations IEC 60115-1 4.16 Direct load for 10 Sec. in the direction of the terminal leads ≥50N Periodic-pulse Overload IEC 60115-1 4.39 4 times RCWV 10,000 cycles (1 Sec. on, 25 Sec. off) ±2.0%+0.05Ω Damp Heat Steady State IEC 60115-1 4.24 40±2°C, 90-95% RH for 56 days, loaded with 0.1 times RCWV ±2.0%+0.05Ω Endurance at 70°C IEC 60115-1 4.25 70±2°C at RCWV (or Umax., Whichever less) for 1,000 Hr.
