2PRO DEVICES The 2Pro product is an integrated overcurrent/ over-voltage protection device. The RoHS-compliant component incorporates PolySwitch PPTC (Polymeric Positive Temperature Coefficient) technology and MOV (Metal Oxide Varistor) technology in a single device to help reduce board space requirements and component count. Damage to telephony communications equipment can be caused by various sources including lightning, electrostatic discharge (ESD), power contact and induction with AC lines. The 2Pro TM2P-10271 devices help provide current limiting during overcurrent events and voltage c lamping during overvoltage events. After a fault c ondition is removed and power is cycled, 2Pro devices will reset so that the equipment remains operational. The 2Pro device helps address the need for resettable circuit protection devices for use in cost-sensitive PSTN (Public Switched Telephone Network) and VoIP (Voice over Internet Protocol) telephony equipment. The widespread use of VoIP gateways in homes and e nterprise environments as the primary means of voice delivery r equires the utmost safety and reliability in equipment. 2Pro circuit protection devices help manufacturers comply with global safety standards, including UL 60950, TIA-968-A, IEC 60950 and ITU-T K.20/K.21. The UL 497A listed protector also helps p rovide ESD protection. APPLICATIONS BENEFITS * Single device helps reduce component count and footprint * Cordless telephones * VoIP gateways * Helps reduce warranty returns * Fax machines * Helps equipment comply with surge tests per: TIA-968-A, IEC 60950, ITU-T K.20/K.21 * Data modems * Helps simplify UL 60950 testing * Security systems * Helps equipment comply with UL 60950 * MDF modules * Set-top boxes * Analog and ISDN linecards FEATURES * RoHS compliant * Halogen free (refers to: Br900ppm, Cl900ppm, Br+Cl1500ppm) * Single overcurrent, overvoltage and ESD protection device * Resettable overcurrent protection RoHS Compliant, ELV Compliant HF Halogen Free Specifications subject to change without notice.
