- 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.
- PROTECTIVE SEAL
Standard: Conformal silicone or epoxy case. Special: Thermal conductive insulating coatings or un-coated.
- MARKING
PRC stamp, part type, resistance value, tolerance & TCR characteristics (physical size permitting).
