CAN'T FIND THE PART TO MATCH YOUR SPECS?

Then let PRC custom manufacture your wire wound resistor, sensor, or shunt with some of the shortest lead times in the industry. Engineering samples can be supplied at no cost to you in 7-10 days for most jobs. Computer tracking charts are available for reference with certain part types. If you need a specific marking on your part(s) we will custom print your order with the marking you desire & at no additional cost to you. If needed, you can interchange the size, shape, lead dimension, wattage, voltage, current, Ω value, tolerance, & TCR characteristics with most part types. Visit our High Precision SX Series & see if one of our other parts from the same series will satisfy all your requirements. If you still do not find a part that meets the exact specifications your application requires, simply follow the link Contact/Request For Quote & fill in all known spec fields. One of our highly trained engineers will review your objectives and see if we can modify one of our standard parts to satisfy all your requirements. If you are unsure how to accurately complete this form, give us a call & someone from our sales department will be more than happy to assist you.

SX Series Engineering Attributes:

RESISTANCE & TOLERANCES
You can select any Ohmic value or decimal part of an Ohm from .01Ω to 6MΩ (MegaOhm or MEG) with tolerances to ±.05%. For closer resistance tolerances refer to the Ultra Precision HR Series
TCR CHARACTERISTIC
Standard:0±10ppm/°C. for 100Ω & higher.
Standard: 0±15ppm/°C. for values below 100Ω
*TCR is calculated between +25°C. & +100°C.
-For lower specific TCRs to ±1ppm/°C., please refer to the Ultra Precision HR Series to satisfy your specifications.
-For higher specific TCRs to ±6000ppm/°C., please refer to the Compensator Series to satisfy your specifications.
POWER VS. AMBIENT TEMPERATURE
All SX High Precision Resistors are designed for full load based upon ±1% resistance tolerance providing the ambient temp (+) the rise in temp. due to self-heating, does not exceed +125°C. Derated to zero power @ +125°C. Refer to Derating Table shown below.
STABILITY VS. TIME
To ±.005%/yr. @ 25°C. with no Load.
REDUCTION OF THERMAL EMF USING COPPER TERMINALS:
Less than ±3 microvolts/°C. emitted.
PROTECTIVE COATING SEAL
Stress free solvent resistant silicone/epoxy seal.
MARKING (Identification)
PRC stamp, part type & name, Ω value & tolerance, physical size permitting.
INDUCTANCE
Standard SX series resistors are inductively wound. Non-inductive windings are available, simply add suffix letter "N" in the part name.
 
*Please specify the ambient temperature span of your operation when placing your order.
