High-temperature performance (up to +275°C).
Very low inductance 0.5nH to 5nH.
Excellent frequency response.
Stable high frequency characteristic with reduced
lead inductance and excellent frequency response.
Low thermal EMF (<1μV/°C).
Pure tin plating provides compatibility with lead
(Pb) free and lead containing soldering processes.
Excellent stability (|ΔR/R| = + 0.5% for 1000hr
at 100°C) different environmental conditions.
