GENERAL ORDERING
INFORMATION
I. ORDERING INFORMATION
Contact the sales office or distributor in your area for ordering information. Visit www.linear.com/contact for a
complete list.
Apply for credit and purchase through Linear Express at www.linear.com/purchase or buy directly on-line with a
credit card.
II. RoHS COMPLIANCE AND LEAD (Pb) FREE PRODUCTS
Visit www.linear.com/leadfree for more information.
a.
In compliance with international Reduction of Hazardous Substances (RoHS) mandates, Linear Technology
supplies Lead-Free Matte Tin terminal plated products on all Plastic Packages (Excluding Hermetic
Packages). Devices with Lead Free terminal plating will have the same basic part numbers with the suffix
#PBF (lead-free) or #TRPBF (tape-and-reel lead-free)) on the container labels. Matte Tin is LTC's standard
terminal finish, although solder plated products will continue to be available for the foreseeable future.
b.
Lead (Pb) Free ordering examples.
Example 1.
Ordering a part in shipping tubes with a Lead (Pb) Free lead finish:
Lead (Pb) Free Part
LT3481EMSE#PBF
Solder Plated Part
LT3481EMSE
Example 2.
Ordering a part in tape and reel with a Lead (Pb) Free lead finish:
Lead (Pb) Free Part
LT3481EMSE#TRPBF
c.
Solder Plated Part
LT3481EMSE#TR
Lead (Pb) Free Markings
JEDEC Standard JESD97 defines various Lead (Pb) Free categories with symbols e1 through e7. The
symbol e3 applies to products with a Matte Tin (Sn) terminal finish. Since LTC Lead (Pb) Free products
have a Matte Tin (Sn) terminal finish, the symbol e3 is added to the product top marking of larger packages,
where space permits. On packages that are too small to accommodate the e3, a "<" symbol is added to the
device at the pin 1 location. Lead (Pb) free 2mm x 2mm and 3mm x 2mm packages are identified by
rearranging the trace code marking of the device. These Lead (Pb) Free marking indicators were
implemented starting with datecode 0514. However, we will continue to ship Pb-Free product, from our
existing stock, which was marked prior to 0514 without the indicator.

VI. TAPE AND REEL
For more information visit www.linear.com/tapeandreel
Tape and Reel packaging is ordered with a ‘#TRPBF’ suffix for lead free finish parts, or a ‘#TR’ suffix for lead
based finish parts. See the Tape and Reel document for reel quantities by package type. Some packages are
available in 500 unit reels through designated sales channels. These packages are noted in the document. 500
unit reels are ordered with a ‘#TRMPBF’ or ‘#TRM’ suffix.
