These chip resistors are available in both “top side” and
“wraparound” termination styles in a variety of sizes. They
incorporate self passivated, enhanced Tantalum Nitride
films, to give superior performance on moisture resistance,
voltage coefficient, power handling and resistance stability.
The terminations consist of an adhesion layer, a leach
resistant nickel barrier, and solder coating. This product will
• 100 % visual inspected per MIL-PRF-55342
• Very low noise and voltage coefficient (< - 30 dB)
• Non-inductive
• Laser-trimmed tolerances to 0.1 %
• Wraparound resistance less than 10 mΩ
• Epoxy bondable termination available
• Compliant to RoHS directive 2002/95/EC
out-perform all requirements of characteristic
MIL-PRF-55342.
