Precision Anti-Corrosive Chip Resistors

PR

Tokenchina introduces PR Series of anti-corrosive precision chip resistors to eliminate moisture concerns associated with typical nickel chromium precision surface mount resistors, The PR features a long term life stability and demonstrated the anti-corrosion claims characterized by Ta2N. Sizes are available in industry standard SMD-0204, SMD-0603, SMD-0805, SMD-1206, SMD-2010, and SMD-2512.


Tokenchina's PR chip resistor are Restriction of Hazardous Substances (RoHS)-compliant and compatible with lead-free.


Detailed specifications, both mechanical and electrical, are maintained for many popular designs on our website, or by contacting our sales representative.
