Riverside, Calif. Bourns, Inc. has announced that its Circuit Protection Division has expanded its line of ceramic Positive Temperature Coefficient (PTC) thermistors for telecom over-current protection. Designated the CMF-SDP series, the new family of resettable fuses provide improved resistance tolerance to ensure continuous circuit protection in customer premise equipment, central office, access equipment and other telecommunication center applications.
The CMF-SDP PTC thermistors are now available in six form factors including a compact dual package that combines two resistance-matched ceramic PTCs together in a single housing to help telecommunications equipment manufacturers reduce the number of circuit protection devices required per board. Other form factors include thru-hole, surface-mount, thru-hole dual and thru-hole quad packaging.
The PTC series is offered as a standard 50-ohm product but other resistive values are available on request. The products can withstand induction voltage of 600 Vac with a rated voltage of 230 volts.
The CMF-SDP family aids compliance with the latest ITU, Telcordia and UL telecommunication standards. The products are RoHS compliant.
Pricing: The CMF SDP50 is priced at $0.35 in quantities of 10,000.
Availability: The CMF-SDP family is available now.
