Sunon Fans PF Series | DigiKey Daily

To meet rising thermal control needs, Sunon has released a selection of its most powerful and efficient PF series DC fans with standard 4-wire pulse-width modulation input and tachometer output functions. The PWM function regulates the voltage-signal between duty-cycles to control the speed of the fan, while the Tachometer wire provides feedback on the fan’s RPM. The PF series is ideal for 1U, 2U, 3U, and 4U applications, ranging from 36mm×28mm to 120mm×28mm in size. Sunon PF series fans are developed with new stator materials with lower electrical conductivity. The result is higher efficiency, higher performance, and lower vibration, a complete cooling solution without compromise.
