Chicago, IL, and Riverside, CA – Bourns offers what it says is a breakthrough in transient blocking unit circuit protection technology, and has expanded, adding Fultec components and modules, by acquisition.
Bourns Inc. has a new line of Transient Blocking Unit (TBU) circuit protection products. The TBU technology blocks a transient through a current disconnecting mechanism rather than diverting or shunting the surge to ground. It virtually eliminates latency in circuit protection design for surge protection of sensitive electronic equipment within nanoseconds. The devices provide wide bandwidth circuit protection against lightning, power induction, power cross, and short circuit events in a variety of Ethernet, Voice over IP (VoIP), Very High Speed DSL (VDSL), and Gigabit Passive Optical Networking (GPON) applications.
The line includes four product families: P-G Series is designed for voice protection, P40 for VDSL protection, P-U Series for Ethernet protection, and C Series for general electronics protection. P-G meets very high surge requirements and prevents arcing and damage to components. Offering very high bandwidth for VDSL and VDSL2 applications, P40 products meet rate-reach requirements. P-U is designed for Ethernet applications, protecting against both lightning and power cross events. All products are resettable for full functionality after multiple fault events and offer a high bandwidth of 3 gigahertz (GHz Specifically designed for overvoltage and overcurrent protection in telecommunication, industrial and data communications systems, TBU technology was first announced by Fultec Semiconductor which Bourns acquired last month.
“As the markets for Ethernet, VoIP, VDSL and GPON solutions continue to grow, new circuit protection technologies will be in high demand,” said Dr. Erik Meijer, vice president of circuit protection at Bourns.
Bourns Fultec Semiconductor’s Transient Blocking Unit (TBU) business. Terms were not disclosed. Headquartered in Mountain View, CA, Fultec designs and manufactures surge protection components and modules primarily for the communications market. Developed to protect electronic circuits, Fultec TBU technology is designed for use in the over-voltage and over-current protection of telecommunication and data communications systems. Fultec has primarily sold TBU products to equipment manufacturers for use in high-speed voice and data-over-broadband applications.
The technology is based on electronic current limiter technology, also known as resettable electronic fuses. It reacts extremely quickly to incoming surges and effectively blocks energy from reaching sensitive and expensive electronic equipment, as well as providing wide bandwidth circuit protection against lightning, power induction, power cross, and short circuit events.
According to Meijer, “Bourns has more than 30 years of experience developing products internally and acquiring important technologies. . . New component technology introductions in the circuit protection arena are rare and we are very excited to add the transient blocking unit technology to our broad range of circuit protection products.”
James Witham, president and CEO of Fultec Semiconductor added that its customers will “now benefit from not only a broader range of superior circuit protection products, but will also have access to Bourns’ extensive global sales and technical support network.”
The acquisition is one of several circuit protection purchases Bourns has made recently, including Emerson Network Power business, Joslyn Electronics’ Communication Protection Products business, Power Innovations’ Thyristor Surge Protector business, and Texas Instruments’ Solid State Telecom Protection business.
