Fairchild Semiconductor’s Dual Cool Package Answers the Need for Higher Power Density in DC-DC Designs
As DC-DC applications, such as power modules, telecommunications and servers, become more space-constrained, designers are looking for smaller devices to meet their design challenges. The thermal capability of these devices, however, is a concern.
New narrow profile CR2032 battery retainer, P/N: BK-913
MPD newest edition to the retainer family is a narrow profile version, P/N BK-913 for 20 mm diameter batteries. Offering a 23% narrower width than other competing designs and weighting just 0.8 grams is just the beginning of its benefits. The very low cost of the BK-913 retainer make it particularly suitable for greeting cards, consumer products, electronic toll tags, single-use devices, RFID other price sensitive applications.
