Round Wire Coil Inductors
Round wire coil (RWC) inductors come in six platform sizes and enable the highest efficiency of any SMT inductor through the use of a low loss ferrite core material which minimizes AC losses and also eliminates thermal ageing. The use of round magnetic wire instead of rectangular flat coils enables a lower cost while still maintaining a low DCR and small footprint. The platforms have passed the AEC-Q200 stress test qualification proving the designs robustness and suitability to difficult environments but the parts are not IATF certified. The platform range from 7.6×7.4×6.4mm to 26x26x15mm and are suitable for a wide range of applications and markets including communications, computing and industrial.

Thermitest
THW-L2
Designed with speed and operational simplicity in mind, the Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. In less than 2 seconds, a single measurement of small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. Using a non-stationary measurement approach, the THW-L2 uses rapid test times to limit convective effects for samples with a wide range of viscosities. The THW sensor consists of a 60 mm heating wire that is fully inserted into an isothermal sample. A constant current source (q) is used to heat the sensor wire and the temperature rise is recorded by monitoring the change in electrical resistance of the wire. The slope (m) is determined from the plot of temperature rise vs. logarithm of time and is used in the calculation of thermal conductivity (λ). Liquid samples of high thermal conductivity will have a lower slope, while liquid samples with low thermal conductivity will have a higher slope.

IR FPA sensors
IR FPA sensors are the most important modules of thermal imagers. Design of sensor electronics (camera core) is a crucial part of designing of new thermal imager. Knowledge of precise parameters of IR FPA sensor is needed by both professionals involved in both IR FPA technology/thermal imagers technology because parameters of IR FPA sensors determine performance limits of thermal imagers. Therefore test equipment that enable measurement of IR FPA sensors is a vital tool for development of both IR FPA technology/thermal imagers technology. It is commonly known that data sheets provided by manufacturers of IR FPA sensors (both cooled or non-cooled) provide too little details for electronics designers. Sometimes the provided data is not accurate enough and better sensor performance can be achieved using modified control signals. Therefore design teams loose sometimes years to develop electronic camera core optimized for a specific IR FPA sensor. When the type of the IR FPA sensor is changed the whole process is to be repeated. In this situation an universal, flexible camera core that would accept IR FPA sensors from different manufacturers and to carry out semi-automatic determination of optimal signal controls for a specific IR FPA sensor would be highly desirable.

Model 7651
Jinan Testing Equipment IE Corporation
Model 7651 extensometers measure combined in-plane strains in flat cruciform specimens tested in machines capable of simultaneous X and Y (perpendicular) axial loading and on standard flat samples tested in pure tension. All models are capable of bi-directional displacement in both axes and may be used for strain-controlled fatigue testing under fully reversed load and strain conditions at frequencies up to 10 Hz.All 7651 models mount rigidly on the load frame and incorporate slide mounting to bring the extensometer into contact with the specimen. The gauge length is set automatically before mounting on the test specimen, which allows for hot mounting after thermal equilibrium has been reached.These units are specifically designed to eliminate crosstalk between axes and to provide high accuracy, high resolution measurements. They incorporate capacitive sensors for low operating force and include electronics with programmable filtering and multi-point linearization for improved performance and accuracy. The overall design minimizes, and in many cases virtually eliminates, any influence from common lab environment vibrations.These water-cooled extensometers are equipped with high purity alumina rods with conical rod tips for specimen contact when testing to 1200℃(2200°F). Silicon carbide rods are used for the 1600℃(2900°F) high temperature option.
