June 2017: Dean Technology announces the recent Product Releases of 2017.

DEAN TECHNOLOGY , Inc. , leader in high Voltage, High Current devices, annunces new products families: long surface Mount HV Diodes, 30KV HV Diodes, High current HV Diodes,  Automotive High Temperature HV Diodes, Miniature HV Power Supplies, HV Ceramic Capacitor Stacks.




May2017: New HV ceramic capacitor stacks the ST1, ST2, and ST3 series.


Dean Technology, Inc.,  announced the introduction of  high voltage ceramic capacitor stacks the ST1,
ST2, and ST3 series. These are a new line of stacked ceramic disc capacitors, with three different terminal 
types that range from 6,000 to 12,000 volts and 130 to 1,000 picofarads per disc. They are made from Class II 
ceramic dielectric materials,with noble metal electrodes,and are all RoHS compliant.
Available as standard parts with four to twelve stages, capacitor stacks are ideal for use in constructing
compact half and full wave multipliers for countless applications including electrostatic paint spraying and
portable x-ray systems. The ST1 series has wire leads between each stage, while the ST2 and ST3 parts
have solder tabs with 180-degree and 140-degree separation respectively. The flexibility and space
efficiency of this product line, when paired with Dean Technology’s lines of HVCA axial lead and surface
mount high voltage diodes offer an impressive design option for new multiplier designs.

April 2017: New Products for Thermal interfaces by Indium Corp.

Indium Corporation announces the phase in of two important materials for high power Applications.
It is a thermal interface material specially designed to solve problems related to the use of thermal grease in applications where the powers and the temperatures do not require metal-type interfaces such as HeatSpring. It is presented in the form of strips or preformed easily be cut by the customer. The main advantages over the thermal grease include:
- solid, easy to handle, non-greasy and non-staining;
- better thermal resistance of the best thermal grease on the market;
- not subject to the pumping phenomenon (leakage of fat) or bake-out (baking and drying);
- vastly superior to the fat in the resistance to thermal cycling
- in essence, much cheaper and reliable than thermal grease.
It is a composite material made by incorporating a copper mesh between two layers of solder. The sheet so obtained may subsequently be cut into any shape (preform) and can be used to weld power components on any metallic substrate. The particular nature of this product allows to obtain extremely robust and reliable welds for the poor consistency of voids (maximum efficiency in heat transfer) and resistant to particularly severe thermal cycles such as those required in the automotive field (complete absence of delamination).
        The thickness may be decided by the customer, but typically the copper mesh is 200 microns thick while the two alloy layers are 25 microns each. The most popular alloy for this product is the alloy # 133 (95Sn5Sb) which has a melting temperature of 237 ° -240 ° C.
Technical details of these materials are available in the following documents:

February 2017: Input transient protections simplifications with new DC-DC converter by Gaia

Gaia Converter extends its ultra wide input voltage range DC/DC Converters platform to the new High Rel MGDD-40 series,  targeting Military and Airborne applications.

New 40W, Ultra Wide input voltage range DC-DC converter from Gaia-Converter simplifies input transient protections

Uniquely wide, the MGDD-40 Series 9-60V & 80V transient input voltage range is ideal to comply with Mil-Std-1275, 704 or DO-160 standards without additional front end protection device. This unique performance is achieved thanks to Gaia's proprietary switching techniques while also keeping efficiency over 90%.

With 2 outputs (for parallel, serial or symmetrical operation) of 5V, 12V, 15V and 24V, they can cover a wide variety of needs such as single 5V to 48V output, or two 24 V for example.

Packaged in a very low profile 0.33'' and 1.5”x1.75” housing, the MGDD-40 Series have a wide temperature range of -55°C to +105°C and are potted to fit rugged Military and Airborne environmental conditions.

The units are full featured and protected with zero to full load regulation, Trim & On/Off capability, adjustable UVLO,  soft start, embedded EMI filter as well as over-current and over-temperature protection. They can also be synchronized and/or paralleled for added power or N+1 redundancy.

Designed for rugged applications, the MGDDI-40 series do not use any optocoupler.

December 2016: VPG - CSM3637F, four term. Bulk Metal Z-Foil High Precision Current Sense Resistors.

Vishay Precision Group, Inc. product group, announced that its Vishay Foil Resistors brand has introduced a new current sense resistor for the medical, energy, military and aerospace markets. The high-precision, surface-mount, four-terminal CSM3637F current sense resistor is an industry first due to its size in combination with an improved load-life stability of ±0.02% at +70°C for 2,000 hours with a low TCR of ±5 ppm/°C max from -55°C to +125°C and a high power rating up to 3 W.
The CSM3637F resistor is optimized for high-precision current sensing applications in switching linear power supplies, power amplifiers, power management systems, feedback circuits, measurement instrumentation and automatic test equipment. The device features a resistance range from 50 mΩ to 200 mΩ with any conceivable ohmic value within this range — out to six digits — available with no additional cost or lead time effect. The resistor provides ESD immunity to 25 kV or more, power coefficient of resistance (ΔR due to self-heating) of 5 ppm/W at rated power, and tight tolerance of ±0.1%.
The CSM3637F resistor’s unique combination of Bulk Metal® Z Foil Technology and a four-terminal Kelvin connection results in a significant reduction of the device’s sensitivity to applied power changes such as power coefficient of resistance (PCR) and thermal resistance, while its low TCR reduces errors due to temperature changes. Short-time overload tests applying 10 W power for 5 seconds on the device were passed with a maximum ∆R of 0.01%.

October 2016 :Johanson Technology releases new 900MHz/2.4GHz IoT Diplexer

In the world of connected devices that use multi-protocol gateways, many IoT, M2M sensors, wearables, AMRs, etc., use multiple RF transceivers or radios that have both Sub-GHz and 2.4G ISM bands in one for versatility. For this purpose, we've developed a simple, low cost diplexer that allows the designer to use one single antenna system and a simplified front-end. This enables one to be FCC & ETSI compliant due to the Low Pass Filter and Band Pass Filter embedded in the component. P/N is: 0900DP15A2450 (click for datasheet).
