Resistance Code
NOTE: Land pattern dimensions are based on
design rules established by the Institute for Inter-
connecting and Packaging Electronic Circuits in
IPC-SM-782.
• First 2 digits are significant
• Third digit represents the
number of zeros to follow.
Resistance Tolerance
• Blank = 2 ꢁ (see ꢂResistance Tolerance” on
next page for resistance range)
• F = 1 ꢁ (100 ohms - 1 megohm)
• D = 0.5 ꢁ (100 ohms - 1 megohm)
Terminations
• All electrical configurations EXCEPT T03:
LF = Tin-plated (RoHS compliant)
• ONLY electrical configuration T03:
L = Tin-plated (RoHS compliant)
• Blank = TinꢀLead-plated
*For tube packaging, use T01, T02, T03 or T04.
Consult factory for other available options.
*RoHS Directive 2002/95/EC Jan 27 2003 including Annex
Specifications are subject to change without notice.
Customers should verify actual device performance in their specific applications.
