Surface Mount Pulse Withstanding Chip Resistors
The pulse withstanding capability of the PWCR Series ranges up to 5 kV for a 2512 size with 1.2/50's and 10/700's pulse shapes as defined by IEC 60-115-1. They are rated for 0.125 W to 1.5 W @ 70°C and benefit from an increased Limiting Element Voltage (LEV) of 150 V for the 0805 size and 500 V for the 2512 size.
The enhanced performance of the PWCR Series resistors is achieved by the use of special thick film inks, and by a specifically developed production process. Applications for the PWCR Series resistors range from line protection for telecommunications equipment to surge withstanding resistors for use in power circuit breakers.
