Heat Sinks Designed for Higher Power Densities
The new R2 Series of heat sinks from Ohmite combines thermal performance with the attachment mechanism of the popular C Series. This heat sink is capable of attaching either a TO-220 or a TO-247 component and is offered in both degreased and black anodized finishes. The convenient camming clip eliminates the need for mounting holes and screws. By eliminating the need for a … [Read more...]
New Capacitors with Low Insertion Height
TDK-EPC has developed a wide range of EPCOS MKP and MKT film capacitors with low insertion heights. The new capacitors with a lead spacing of 37.5 mm feature insertion heights of only 15 or 19 mm. These components are designed for rated voltages of between 63 and 2000 V DC or 250 to 400 V AC. Their capacitance ranges from 0.1 to 82 µF. Depending on type and technology (MKT or … [Read more...]
Precision High Voltage Modules
Spellman High Voltage Electronics Corporation’s new V6 high precision, cost-effective high voltage modules on a common platform include either AC or DC input, with analog or digital interface (RS232) capabilities. The V6 Series offers output voltages ranging from 500V to 30kV, and incorporates the high precision features of Spellman’s 600 Series (replacing the 602C, 603C, 605C … [Read more...]
Thermal Modeling and Testing for LEDs and Luminaires
Mentor Graphics Corp. has introduced the T3Ster (“trister”) thermal transient tester for LEDs, board-level LED arrays and luminaires. Together with the company’s FloTHERM thermal simulation tool based on computational flow dynamics (CFD), lighting designers can model and improve heat transfer through the LED, printed circuit board (PCB) or luminaire system during design and … [Read more...]
