ITG Electronics is aiming at server motherboards and storage devices with a series of high-current surface-mount ferrite inductors. The SLA36385A series has a 5 x 9mm footprint and 9.5mm height, and yet the components can handle up to 230A. Inductances range across 35 to 470nH. “The 35nH component can handle more than 200A, with approximately 20% roll off”, said the ...

Bourns has created a series of self-resetting fuses that can carry from 12 to 20A at 60°C. Called Model NX, they measure 2.8 x 9.8mm including two 2.8 x 2.5mm flat connecting tabs, one at each end. Height is just under 1mm. “While our new Model NX Series has the same footprint as our Model NR series, it can carry ...

Knowles has introduced two series of triple cell PCB-mount supercapacitor modules, based on Cornell Dubilier’s DGH and DSF series, which it now owns. DGH types work up to 8.1V (-40 to +65°C) and measure between 25 x 8.5 x 16mm high for the 330mF version, to 39 x 13 x 33mm for the 5F. They will also work up to ...

Panasonic has introduced the ZV Series –  an Electrolytic Polymer Hybrid capacitor with advanced characteristics. It achieves a maximum Ripple Current (3.3~4.6 Arms) – claimed to be approximately 50% higher than comparable case-sizes.  While comparable capacitors usually come up with a ESR of around 16 mΩ at 35V, the ZV series has an ESR of 12 mΩ at this voltage ...

Murata has announced multi-amp miniature automotive SMD inductors that are over 30% better than their forebears. Measuring 2 x 1.6 x 1.2mm (0806 or 2016), there are two types: DFE2MCPHR33MJLLQ 0.33μH ±20%, 0.018Ω 5.1A max (6.4A typ) at 40°C rise 6.9A max (8.1A typ) at 30% inductance change DFE2MCPHR47MJLLQ 0.47μH±20%, 0.022Ω 4.4A max (5.5A typ) at 40°C rise 5.4A max ...

ITG Electronics will feature 600Vac common-mode chokes at APEC in February, which offer “higher voltage ratings and more robust hipot Isolation between two windings – the products address increasing demand for industrial, under-the-hood inverter applications”, it said. That hipot isolation is 2,500Vac. There are two series: C301306H measuring 44 x 48 x 34mm, and C301369H at 34 x 35 x 26mm. ...

The SiT5503 Elite X Super-TCXO uses MEMS technology to replace bulky quartz OCXOs to offer a device that is four-times smaller with four-times lower power consumption for enhanced timing performance in data centres and 5G infrastructure. The judges were impressed with this innovative timing product with a wide range of applications. Highly commended – STMicroelectronics Shortlist * Harting – Han ...

Spectrum Control has introduced a family of modular power EMI filters for designs meeting MIL-STD-461. 52F1825 filters operate across -55° to 75°C and the “rugged design includes a convenient, environmentally sealed input interface that withstands moisture, dust, and other contaminants to ensure durability and longevity”, according to the company. The models come with a 89 x 127mm footprint in a ...

Kemet has introduced three automotive grade supercapacitors. “Optimised design and materials enable a service life of up to 1,000 hours at 85°C or 105°C, and the components meet the special requirements of the 85°C, 85% relative humidity, 1,000 hour test [‘THB test’] for the automotive industry,” according to distributor Rutronik, which is stocking the parts. “Thanks to their characteristics, the ...

Epishine, the Swedish indoor solar power specialist, and Nichicon, the Japanese capacitor manufacturer, have come up with a self-charging battery concept. The idea is to combine Epishine’s  solar cells and Nichicon’s  LTO-batteries in an integrated solderless autonomous power product which is an alternative  to disposable and re-chargeable batteries, reducing time-to-market and cutting down on product development costs. “We’ve created a ...
