Surface Mount Resistors (SMR) are best suited for commercial industrial andautomotive applications. Chip Resistors are suitable for a wide range of solder processes, and are ideal for high-speed electronic assembly equipment. Chip Resistor body sizes range from 0201 to 2512. Seven-inch reels are standard, but eleven and thirteen-inch reels sizes are available. Paper carrier tape is standard for Chip Resistors. Zero-Ohm Resistors are also available. Zero-Ohm Chip Resistors have a copper wire internally. This creates a short condition. Zero-Ohm Chip Resistors can be used to check for continuity after soldering.
Lead-Free Surface Mount Resistors (SMR) are now available with 100% tin terminations, which is recommended for solder attachment applications due to the barrier’s increased ability to resist silver leaching that can occur after prolonged exposure to soldering temperatures.

- Surface mount resistors come packaged on paper carrier tape and 7" reels (larger quantities available upon request).
- Plastic carrier tape is non-standard for surface mount resistors.
- PA = paper tape.
- Add a “B” to the end of the part number for bulk.
- Add a “C” to the end of the part number for bulk cassette feeder.
- The numeric section of the part number refers to the physical body size (in inches) of the component. For example: Part number 0402SMR-PA has a body size of .04" length by .02" width.
- Chip resistor arrays are available.
- Lead-free parts are available with 100% Sn alloy.
