RC Series
Carbon Composition Resistor
Technical Guide:
Stackpole Electronics, Inc.
Resistive Product Solutions
1. Storage Conditions:
Temperature:
5 to 35ºC (40 to 95ºF)
Humidity:
25 – 60% relative humidity
Term:
Two years in factory poly-bag with desiccant. If parts are removed from the poly-bag,
they should be used immediately or resealed in the bag.
Environment:
Clean, dry environment, free of corrosive gases
2. Application precautions:
Lead forming:
Forming is recommended at least 2mm of farther from the base of the lead
Soldering:
Soldering is recommended at least 4mm or farther from the base of the lead
3. Washing:
Carbon composition resistors are highly hygroscopic and changes in resistance value can occur if too much
moisture is absorbed. For this reason it is recommended not to use water or water-soluble solvents to clean these
components. Alcohol or hydrocarbon solvents are recommended for rinsing.
4. Soldering Recommendations:
Note: The conditions shown below are for reference. Please perform a mounting evaluation to assure compatibility.
a. Flow soldering (recommended profile for Sn and Sn/Pb solders)
b. Soldering iron (recommended for Sn and Sn/Pb solders)
Temperature of soldering tip:
300ºC, duration: 10 sec. max.
Temperature of soldering tip:
350ºC, duration: 3 sec. max.
Other:
1. Evaluate and confirm the compatibility of your assembly process with this product.
2. Refer to the catalog, the product news, and the specifications for details on the RC series resistors.
3. If you have any questions, please contact our sales staff.
