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 PVS Shunt 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.

Electrical & Physical Specifications:

PVS Series Engineering Attributes:

RESISTANCE & TOLERANCES

Select any Ohmic value (Ω) or decimal part of an Ohm from .001Ω to 100KΩ with micro-ohm/micro-volt accuracies to ±.005%. See Figure #2 shown below for the minimum resistance vs. tolerance requirements. PRC's unique single-joint design on the four (4) terminal parts make tab identification academic.

TCR CHARACTERISTICS

0±15 PPM/°C is the standard for this part type. Add LTC in the part name for a lower TCR of 0±10 PPM/°C. This Low Temperature Coefficient (LTC) is only sustainable if the combined temperature of self-heating and ambient (surrounding environment) operating temperature does not exceed +150°C. Please specify temp. span of operation.

STABILITY VS. TIME

To ±.001%/yr. @ 25°C. with no load.

PRECISION POWER

Min. Res. @ Max Watts is based upon ±1% resistance tolerances @ +25°C. Derating is required for higher temperatures, closer tolerances & lower resistance values. See Figure #3 shown below for derating requirements.

PROTECTIVE SEAL

Rectangular solvent-resistant epoxy case is solder heat resistant & offers excellent thermal transfer to base.

TERMINALS

Solderable hot-tinned pure copper (ETP/OFHC) tab terminals & low EMF construction reduces thermal effects usually associated with low value resistors.

MARKING (Identification)

PRC stamp, part type & name, Ω value & tolerance, physical size permitting.

TAPE & REEL

Have your parts delivered to you in tape & reel form by simply specifying Tape & Reel instead of bulk when placing your order. For detailed information on all the individual specifications for the tape & reel delivery option, click the Tape & Reel Chart
