Bourns® Sensors & Controls Division
Announces Model 3540 Series Material Change
Bourns® Sensors and Controls Division will be changing the plastic material used in molding the terminal
block of our Models 3540, 3541, 3543 and 3545. The change from Fortron 6165A4 to Thermocomp®
OF-1008 is due to a phase out of the Fortron material at our current supplier and the lack of availability
from other suppliers.
Thermocomp® material is equivalent to the Fortron material
and has been qualified for use in the standard 3540 series
product. Please reference the adjacent photo identifying the
terminal block. There is no change in fit, form or function on
any of the models listed.
The transition to Thermocomp® material is currently in
progress for standard catalog part numbers. Thermocomp®
plastic is a UL rated (V-0) engineering material. Attached you
will find data sheets for both Fortron and Thermocomp®
plastics for your review. The UL certification for Thermocomp®
is QMFZ2.E45195 and is available on the UL website at
www.ul.com
.
Thermocomp® is a registered trademark of General Electric Custom Engineered Products Division.

FORTRON 6165A4 | PPS-X65 | Mineral / Glass Reinforced
Description
Fortron 6165A4 offers a unique balance of properties based on a high mineral and glass reinforced composition.
The heat resistance under load bearing conditions is excellent for this product. As with all Fortron grades this
product is inherently flame-retardant. Applications include electronic components (i.e. lamp houses, connection
parts and sockets) and components in industry (i.e. pumps and pistons).
