Resistors offer power ratings up to 6W

A family of high-power resistors has been added to the New Yorker Electronics passive component portfolio. The Vishay Dale Thin Film PCAN Series of resistor are built on aluminum nitride substrates, and offer power ratings to 6W and resistance from 2Ω to 30kΩ in 1206 and 2512 case sizes. They are optimised as snubber circuits and burden, gate load and amplifier termination resistors in industrial, military and medical applications.

Other applications include power supplies, power switching and braking systems.

The PCAN series of chip resistors is designed on aluminum nitride ceramic substrates with enlarged backside terminations to reduce the thermal resistance between the topside resistor layer and the solder joint on the end users circuit assembly. Features of the thin film resistors include a resistance range up to 175Ω, tolerance to ±0.1% and TCR down to ±25ppm/C.

Actual power-handling capability is limited by the end-user mounting process. As with any high-power chip resistor, the ability to remove the heat is critical to the overall performance of the device.

The resistors offer 2x the power rating over traditional thin-film chip resistors in the same case sizes and are designed with enlarged backside terminations to reduce the thermal resistance. They are available with lead (PB)-free or lead terminations and are RoHS compliant.

The operating temperature range is -55°C to +150°C
