Precision Resistor Co., Inc. T.C.R Compensator Precision Wire Wound Resistor AT Series

Body Dimensions: H-Height 3.18mm (.125") L-Length 9.14mm (.360") W-Width 3.18mm (.125") Lead dimensions: .02" x 1" long (min.) Compensator Attributes: LINEAR COMPENSATION PRC's type PT/ST (+) TCR Characteristics +3500 PPM/°C. linear tracking temperature sensitive resistors help you develop the desired compensation for true RMS measurements...and can offset errors in dB output circuits. TOLERANCE FOR (+) 3500 PPM/°C. > ±100 PPM/°C from +25°C. to 100°C. For example, If you are looking for a systems offset of +3350 PPM/°C to 3450 PPM/°C...try a few engineering samples of our (std.) off-the-shelf compensators. We are confident you can achieve dramatic results. The element wire used on our type PT/ST, as a rule, is very close to +3350 PPM/°C. @ 25°C. & lower than +3450 PPM/°C. @ 100°C. See figure #4 shown below. OFF THE SHELF FOR IMMEDIATE DELIVERY Thru-hole & SMD designs are available for evaluation & testing. We have our PT series for 2 terminal type or our AT35 for 4 terminal type. If you have plans for SMT our type ST35 is a drop in replacement for the thru-hole part w/ interchangeable specs. All our (std.) 1000ω ±1% +3500 PPM Compensators are in stock! CUSTOM COMPENSATORS We can customize any of our compensators to fit your specs in any Ohmic value from 1ω to 50Kω We have pure metals, alloys, & composite windings available. All of which are extremely linear, reasonably priced & delivered quickly. TRACKING CHART Constant temperature oil bath computer tracking charts are available to match your temperature span & behavior specs exactly. COMPENSATORS VS. POWER PRC's positive (+) TCR resistors are used to offset negative (-) ambient temperature changes or counter self-generating shifts in resistance w/ an excitation of power to .25W @ +125°C. (Derated to 0W @ +150°C.) STABILITY (No Load) Standard: ±.05%/year @ 25°C.; Special: < ±.01%/year @ 25°C. TCR CHARACTERISTICS AVAILABLE Temperature Coefficient of Resistance (TCR*) +80 ppm/°C +3930 ppm/°C +140 ppm/°C +4300 ppm/°C +400 ppm/°C +4500 ppm/°C +1400 ppm/°C +5000 ppm/°C +3500 ppm/°C +6000 ppm/°C
