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 SM 2-Terminal 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.

SM Series Engineering Attributes:

RESISTANCE RANGE: PRC's sub-miniature (SM) type precision power resistors offer the widest range of Ohmic values anywhere. You can select any Ohmic value or decimal part of an Ohm from .02Ω to 4MΩ (MegaOhm or MEG)
CUSTOM TOLERANCES: ±1% (Std) Also available: ±.5%, ±.25%, ±.1%, ±.05%
TCR CHARACTERISTICS
Standard:: For 100Ω & Above: 0±10ppm/°C.; For values below 100Ω: 0±15ppm/°C.
Special:: To 0±2ppm/°C.; *Please specify temperature span of operation.
INDUCTANCE: All standard SM series resistors are inductively wound. Non-inductive windings are available upon request, simply add suffix letter "N" to the part name when ordering.
TERMINALS: Solderable hot tinned pure copper leads are standard at PRC.
PROTECTIVE SEAL: SM type resistors are coated in a tough solvent resistant high temperature silicone formulation with indelible marking.
PRECISION POWER RATINGS: All standard ±1% tolerance type SM resistors are designed for continuous full load operation at +25°C Derating to zero wattage at +275°C. Derating is required for any tolerance below 1%. Refer to Derating Table seen here & Figure #5 at the bottom of the page.

Type SM Derating Table:*

For ± 1% resistance tolerance apply up to 100% of rated power at +25 Degrees Celsius, derated to zero power at +275 Degrees Celsius.

For ± Ω% (0.5%) resistance tolerance apply up to 80% of rated power at +25 Degrees Celsius, derated to zero power at +225 Degrees Celsius.

For ± _% (0.25%) resistance tolerance apply up to 60% of rated power at +25 Degrees Celsius, derated to zero power at +175 Degrees Celsius.

For ± 1/10% (0.1%) resistance tolerance apply up to 40% of rated power at +25 Degrees Celsius. derated to zero power at +125 Degrees Celsius.

For ± 1/20% (0.05%) resistance tolerance apply up to 20% of rated power at +25 Degrees Celsius, derated to zero power at +75 Degrees Celsius.
