Bourns® 1840 Model Signal and Dataline
Protectors are high performance Surge Protection Devices (SPD) designed
to protect sensitive electronic circuits and components from damaging
surge voltages and currents. Features include low peak clamping voltage,
ability to repeatedly protect against surge, convenient DIN-1 and DIN-3
rail mounting, and cable shields that may be either grounded or
arc-protected to ground. The device's extremely fast response and low
clamping voltages make the series well-suited for the protection of
sensitive signal and datalines associated with computer, data
communication, instrumentation, broadcasting and industrial controls.
The devices may be used directly with EIA standard interfaces RS-232,
RS-422, RS-423, RS-485 and with 4-20 mA and 50 mA instrumentation loops.
The Model 1840 Model Signal and Dataline Protectors are fast, rugged
and capable of protecting against fast rising voltage transients as well
as the severe current surges associated with lightning discharges, in
each case up to rated limits.

Additional features include knurled or plain metal shaft, ohm resistance values from 25k to 500k, low impedance, and long bushing option.
Bourns PTVS15 High Current TVS Diodes provide bidirectional port protection in high power DC bus clamping applications. Designed to meet IEC 61000-4-5 8/20 μs current surge requirements, PTVS15 TVS Diodes offer a 15 kA, 8/20 μs surge capability, low clamping voltage under surge, and excellent performance over temperature. These RoHS compliant and UL recognized devices are available in a surface mount package with standoff voltage ratings of 58 V and 76 V.
Bourns automotive CGA-MLC series ESD protectors are sub-1pF protectors designed specifically for use in automotive circuits requiring ESD protection. The CGA-MLC series is available in industry standard 0402 and 0603 packages. In addition to its very low capacitance, these protectors exhibit extremely fast response times to ESD events making them ideal for protecting a wide array of high speed digital electronic applications. The ChipGuard Automotive MLC Series is fully AEC-Q200 qualified and support.
Bourns dual polarity SLIC surge protector is a programmable over-voltage protection device designed to protect modern dual polarity supply rail ringing SLICs (Subscriber Line Interface Circuits) against over-voltages on the telephone line. Over-voltages can be caused by lightning, a.c. power contact, and induction. Four separate protection structures are used; two positive and two negative to provide optimum protection during Metallic (Differential) and Longitudinal (Common Mode) protection conditions in both polarities. Dynamic protection performance is specified under typical international surge waveforms from Telcordia GR-1089-CORE, ITU-T K.44 and YD/T 950. The Model TISP9110MDM is programmed by connecting the G1 and G2 gate terminals to the negative (-V(BAT)) and positive (+V(BAT)) SLIC Battery supplies respectively. This creates a protector operating at typically +1.4V above +V(BAT) and -1.4V below -V(BAT) under a.c. power induction and power contact conditions. The protector gate circuitry incorporates 4 separate buffer transistors designed to provide independent control for each protection element. The gate buffer transistors minimize supply regulation issues by reducing the gate current drawn to around 5mA, while the high voltage base emitter structures eliminate the need for expensive reverse bias protection gate diodes. Bourns dual polarity SLIC surge protector is rated for common surges contained in regulatory requirements such as ITU-T K.20, K.45, Telcordia GR-1089- CORE, YD/T 950. With the use of appropriate over-current protection devices such as the Bourns Multifuse and Telefuse devices, circuits can be designed to comply with modern telecom standards.
Bourns AMS22B Non-Contacting Analog Rotary Position Sensors are designed to meet the specifications of heavy-duty applications requiring long cycle life and high reliability. These single-turn rotary sensors each feature a 1/4" stainless steel shaft supported by a bronze sleeve bearing and a factory programmable electrical angle from 10 to 360 degrees. Available in a bushing mount configuration with a rotational life of up to 50 million cycles, the AMS22B sensor is a highly versatile panel mount position sensing device.
Bourns EVAL-CN0313-SDPZ RS-485 Certified EMC-Compliant Interface Design Tool is the industry's first solution for compliance to EMC regulations -- the #1 design challenge for industrial communications ports. This design tool allows testing of circuits at the beginning of the design cycle which saves time and expenses. The use of schematics and layout serves as a starting point in the design. Internal design work and externally certified EMC compliance provides an ideal starting point for EMC design at the beginning of a project. EVAL-CN03130-SDPZ contains an ADI ADM3485E RS-485 transceiver along with Bourns® external protection components. This design tool is well-suited for any application using the RS-485 electrical standard, such as industrial automation, process control, motor control, motion control, remote terminals, building automation, security systems, and renewable energy.
