The PoC (Power Over Coaxial) method is becoming more popular as high-speed in-vehicle interface. The bias-T circuit is required at the PoC, and the inductors must be selected to pass the criteria. Murata’s “Bias-T Inductor Design Support Tool” solves the issue - the optimal products and combination for PoC bias-T inductors can be found by simple operations.
The SPMxx series of encapsulated DC-DC converters are highly reliable and designed for harsh environment applications with 88% efficiency Designed specifically for use in electronic equipment that will be subject to harsh environments such as outdoor communications, applications with little or no forced air cooling, smart grid and industrial process control equipment. The SPM15 series was designed for applications that require Vin ranges of 9-36V or 18-75V @ 15W. The SPM25 series covers applications that require Vin = 36-75V @ 25W.
The SPM15 & SPM25 series provides single output voltages of 3.3, 5 or 12 VDC. In addition, the SPM15 has a 15 VDC output option. The SPM15 is available with two wide input range options of 9 – 36 VDC or 18 – 75 VDC. The SPM25 accommodates an input range around a 48 VDC nominal from 36 – 75 VDC. The operating temperature range is from – 40 degrees C to + 85 degrees C, designed for use in the most demanding environments.
These compact, 5-sided shielded, encapsulated converters, measuring 1” (25.4) x 1” (25.4) x 0.41” (10.41) mm offer an industry standard footprint, incorporate the latest PWM technologies, automated assembly processes and synchronous rectification techniques to achieve one of the industry’s highest energy efficiency ratings of 88%. A thermally conductive encapsulation material greatly improves the thermal performance in applications where there is little or no airflow, provides a stable platform for environments where dirt & dust, vibration or extreme temperature variations are likely to occur during normal operation.
Protection features include over-current, over-temperature and under-voltage lockout. Basic insulation provides input to output isolation of 1,600 VDC.
The SPM series provides systems design engineers with a contemporary solution for the most demanding, high reliability applications. The SPMxx series can be used as a means to address the growing requirements for dc/dc converters designed for the most sever commercial applications.
Murata Power Solutions will be exhibiting at electronica in Munich, Germany, from 9-12 November 2010, booth B5:107.
For the first time, we will be part of Murata’s stand in the passives hall (B5). Visitors will be able to see a demonstration from Murata Girl, the unicycling robot, and technical experts from both Murata and Murata Power Solutions will be on hand to answer any questions about our extensive product offering.
Visitors will be able to see a demonstration of the unicycling robot, Murata Girl!
Murata Power Solutions is proud to be a finalist in EDN magazine's 20th Annual Innovation Awards Competition. Our OKL series has been selected from hundreds of nominations to be a finalist for this year's awards. If you can take a few minutes to review the nominations, we would appreciate your vote. And you might find the OKL is a great fit for your point-of-load application.
Instituted in 1990, the Innovation Awards honor the people, products, and technologies that have shaped the industry over the past year. Nominees must have demonstrated innovation that resulted in a significant advance in technology and/or product development during the past 12 months, and the OKL design did just that!
The key design feature of the Okami OKL range of PoL DC/DC converters is the innovative iLGA (inspectable land grid array) package, which features small plated cut-outs (castellations) that allow easy access for visual inspection as well as test probe access to all pads. The iLGA package overcomes problems associated with testing and inspecting conventional LGA packages. It also supports greater reliability in customer PoL applications.
