Electrical Specifications
RESISTANCE AND TOLERANCES:
0.001 ohm to 100 ohms in any specified value or decimal part of an ohm - to ±0.005% - see Figure 2 below.
TCR CHARACTERISTICS:
0±15 PPM/°C (std.) to ±10 PPM/°C upon request.
POWER RATINGS:
All resistance values at full power are based upon ±1% resistance tolerance at 25°C. Derating is required for higher temperatures and/or closer tolerances.
PROTECTIVE ENCAPSULATION:
High temperature epoxy.
TERMINALS:
Heavy-duty commercially pure copper test leads match current rating of shunt selected. Also Four(4) low EMF copper terminals are available for very accurate current-sensing applications.
MARKING:
PRC symbol, type, resistance value, tolerance and terminals. Custom marking, if specified. e.g. MS-40A = 0.001 ohm (to 40 amps).
PURCHASING INFORMATION:
Please specify (where they apply): Quantity, PRC type or resistance value, resistance tolerance, DC current, wattage, TCR characteristic, and temperature span of operation and terminals required.
REMEMBER: If you are looking for an easy and inexpensive method to test for high current in charging systems for motorcycles, ATVs, personal water crafts & other recreational type vehicles, then PRC's popular MS-40 Meter Shunts (which include heavy-duty test leads) are ideal for these types of applications & readily available for delivery within one week.
CUSTOMIZED SHUNTS: We can also customize any of our MS shunts to your specs ... in any ohmic value from 0.001 ohm to 100 ohms ... with several 2 & 4 terminal designs for power or current-sensing applications. All of which are reasonably priced with quick deliveries. ... And, yes we accept VISA & MasterCard!
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. You can check our Online Store or visit our Shunt Page & see if one of our other parts 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 & our sales department will be pleased to assist you.
