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.

Notes
- Surface mount resistors come packaged on paper carrier tape and 7"
reels (larger quantities are available upon request). - Plastic carrier tape is non-standard for surface mount resistors.
- 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 (call for availability).
- Resistors are now only available standard lead-free with
100% Sn over Ni.
