High-Voltage Thick Film ResistorsHigh-Voltage Thick Film Resistors - Riedon’s HTE series uses thick film technology in a non-inductive cylindrical construction for through-hole mounting. They provide resistance values from 1 kΩ to 100 MΩ, while also achieving non-inductive performance and a TCR rating of ±100 ppm.  More...

MSR Series Ultra-Low Ohm, Current Sense, Through-Hole ResistorMSR Series Ultra-Low Ohm, Current Sense, Through-Hole Resistor - The MSR series from Riedon uses a bare metal element in an all-welded construction for through-hole circuit board mounting to provide resistance values from 5 mΩ to 100 mΩ, while also achieving low inductance (<10 nH) and low TCR (±20 ppm/°C). MSR resistors are available in 1 W, 3 W, and 5 W power ratings with tolerances of ±1% or ±5%.  More...
