  • 2 A Step Down DC - DC Switching Regulator

    STEVAL-ISA198V1 - STMicroelectronics

    The STEVAL-ISA198V1 product evaluation board is a step-down switching power supply based on the L7987L regulator in an HTSSOP16 package. The output voltage can be set starting from 0.8 V. Low drop-out operation, due to the advanced integrated switch management, can be achieved. The L7987L is a 61 V, 2 A step-down asynchronous switching regulator with embedded power MOSFET capable of delivering up to 2 A of current, depending on the application conditions. The embedded switch-over feature on the VBIAS pin and the light load management (pulse skipping) help maximize power conversion efficiency across the entire load range. The soft-start, current limit threshold and switching frequency are adjustable for application optimization. The device includes an internal 250 kHz oscillator that can be externally adjusted up to 1.5 MHz; two L7987L regulators can be synchronized in a 180° out-of-phase configuration for reduced total input RMS current.

  • Adjustable Clamshell Bed of Nails Testers

    AdjustaBON Family - Test Electronics

    Designed for quick test development. This fixture can be configured to probe almost any circuit board in just a few hours. Once the perfect test is developed, move this light weight fixture out to the production floor to evaluate your production line test strategy prior to buying permanently drilled test fixtures, or while waiting for your drilled fixtures to be delivered. The AdjustaBON competes with the Flying Prober. There are many advantages over the flying prober. Setup is simple and intuitive and can be much quicker than programming a flying prober. Small size provides versatile bench top operation right where you need it. Maintenance costs are insignificant in comparison. The total cost of this fixture is in many cases less than the yearly maintenance cost of a flying prober. It would be possible to buy one of these fixtures every year for the price paid just to maintain one flying prober and it is about 1/20th the purchase price

  • OTDRs and Fault Locator

    AFL

    AFL optical time domain reflectometers (OTDRs) and fault locators are used to certify new fiber installations and locate faults in deployed fiber optic networks. OTDRs and fault locators are available for both multimode and single-mode networks, including FTTx PONs. OTDRs scan fiber optic networks from one end of the fiber, displaying a trace and reporting detected events such as splices, connectors, micro- or macro-bends and fiber end. Fiber length is reported along with location, loss and reflectance of detected events. Several OTDRs are available with an integrated visual fault locator (VFL), optical light source (OLS), and/or optical power meter (OPM). OTDR results can be saved and uploaded to PC for further analysis and/or archiving.

  • IR Sensor

    JonDeTech

    The world’s thinnest IR sensor. JonDeTech’s new generation thermopiles generates a direct, proportional voltage response when subjected to infrared radiation. The sensor registers wavelengths from 250nm – 22,5μm i.e. visual light up to the mid infrared region. The unique geometrical configuration where the thermocouples are “vertically” arranged enable the sensor to measure heat flux as well as temperature, i.e. the heat gradient over the thickness of the thermopile chip is actually measured. The sensor measures a very useful 0.17 mm in thickness and is made of plastic.Essentially it is a piece of robust plastic that can be used “bare” – withoutprotective housing, such as a metal casing commonly used by other producersThe sensor it is less than 0.2 mm. thin and it is made using plastic membrane. This configuration make the sensor so robust it can be used “bare” – without protective housing such as a metal container. Our sensors enables unique applications within the temperature and flux measurement fields
