Designed specifically as a surface mount device, the P3188 features a 7mm seated height and is vacuum encapsulated and tested to 6500VDC. The part is compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow. P3188 offers fully reinforced insulation, is ideal for voice telecommunications and low speed data communications, and can be matched to both 600Ω and complex impedance telephone lines. 600Ω telephone lines are matched directly by P3188 without external compensation components. In instrumentation applications, the P3188 can provide wideband frequency response from 50Hz to 50kHz. P3188 is certified to IEC 60950 and UL 60950. P3188 is a UL Recognized Component, and is supported by an IEC CB Test Certificate.
