Power Resistor Thick Film Technology

FEATURES

• 50 W at 25 °C case temperature heatsink

mounted

• Direct mounting ceramic on heatsink

• Broad resistance range: 0.010  to 550 k

• Non inductive

• TO-220 package: Compact and easy to mount

• Material categorization: For definitions of compliance

please see www.vishay.com/doc?99912

LTO series are the extension of RTO types. We used the

direct ceramic mounting design (no metal tab) of our RCH

power resistors applied to semiconductor packages.
