Bourns Featured Products

Bourns PTVS3-0xxC-TH High Current, Bi-Directional TVS Diodes

Bourns PTVS3-0xxC-TH High Current, Bi-Directional TVS Diodes offer bidirectional port protection and are designed for use in high power DC bus clamping applications. These Bourns devices offer bidirectional port protection and are available with standoff voltage ratings of 58V and 76V. PTVS3-0xxC-TH provide very high surge current protection (3kA @ 25ºC). These TVS diodes exhibit an excellent surge response versus temperature. The typical maximum surge current at 150°C is 75% their rated value at 25°C.

Bourns Model 1840 DIN Rail Signal and Data Line Protectors

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.

Bourns Dual Polarity SLIC Surge Protector

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

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 Interface Design Tool

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.
