The RT1220 series thin film trimmable chip resistors from Susumu offer the designer patented trimming method (Patent# 1921853) which guarantees precision trimming, post trimming stability and short trimming time. The Susumu RT1220 series initial resistance values from 33Ω to 100kΩ and the maximum resistance valves when the parts have been trimmed from 4.7kΩ, to 220kΩ. The power rating is 0.1W with a maximum voltage of 100V and the initial tolerance value of ±20% with a chip size of 0805.
