PCNM Non-Magnetic Chip Resistors Vishay / Thin Film PCNM Non-Magnetic Chip Resistors provide four times the power-handling capability of previous generation non-magnetic resistors. PCNM resistors are designed on aluminum nitride ceramic substrates with enlarged backside terminations. This construction design reduces the thermal resistance between the topside resistor layer and the solder joint on the end user's circuit assembly. Vishay / Thin Film PCNM Non-Magnetic Chip Resistors feature a power rating of up to 6W and a resistance range from 2Ω to 30.1kΩ. The series is ideal for use in power supplies, power switching, and braking systems.
