PLT Series Chip Resistors Vishay / Thin Film PLT Series Chip Resistors are ideal for precision applications that require low noise, stability, ultra low temperature coefficient of resistance, and low voltage coefficient. The surface mountable PLT Series resistors from Vishay Thin Film have a TCR of ±5ppm/°C as standard and tolerances to ±0.01%. In addition, these halogen-free, RoHS-compliant resistors offer anti-corrosion resistant film with (SPM) special passivation method and stable film and performance characteristics.
