Resistors SP5-21 - variable adjustment wire resistors, potentiometers, power of 3 W with a linear dependence of A and an adjustment range of 100 ohms - 15 ohms. SP5-21 Resistors are multi-turn resistors with a circular movement of the mobile system. Admissible resistance tolerance of ± 5% deviation from linearity of ± 0.3% to ± 1%. Resistors have the acceptance of "OTC" and "PP". Working elevated temperature does not exceed + 155 ° C, reduced - up to -60 ° C. Durability - up to 50 000 cycles moving the slider. Variable resistors SP5-21 resistant to vibration loads ranging 1-3000Gts (acceleration amplitude of 150 m / s2) frequencies single mechanical shock (acceleration 1,500 m / s2) and repeated operation (acceleration of 350 m / s2). Designed for use in AC or DC circuits (frequency up to 400 Hz), providing current limiting and voltage distribution.
Marking resistors SP5-21: SP 5 - 21 - 2 SP - Trimmer with a circular movement of the mobile system. 5 - wire type resistor. 21 - part type resistor. B - type on the durability of the resistor. 2 - The number of sections.
