Empower Semiconductor is aiming at high-performance decoupling within IC substrates and interposers with its largest silicon capacitor yet, the 16.6μF EC1005P. “The performance of SoCs and other large computing processors are constantly increasing, said  Empower marketing manager Mukund Krishna. “It is becoming increasingly difficult to reach the level of power integrity and voltage regulation that these devices require with conventional ...

Component distributor Rutronik is offering a series of tiny surface-mount magnetically shielded power inductor from Knitter, The ICSIxxxxxxTxSHyST12 series spans sizes between 1.6 x 0.8 x 0.8mm and 6.6 x 6.4 x 3.1mm, inductance from 0.1 to 10μH and saturation currents from 1.3 to 35A. “The inductor series works reliably at operating temperatures from -40 to +125°C and is suitable ...

Kyocera AVX has launched two series of snap-in -25 to 105°C electrolytic capacitors for commercial and industrial applications. SNA capacitors are rated for a life of 5,000 hours. Voltage ratings are 250, 420 or 450Vdc, capacitance is between 82 and 1,500µF (±20%), and there are 24 case sizes spanning 22mm diameter x 25mm long to 35∅ x 50mm. As well ...

Samsung is aiming at electric vehicle on-board chargers with a 1,000v 22nF multi-layer ceramic capacitor. CL32C223JIV1PN# (yes, there is a # in the part number) is aimed at CLLC resonant power supply topologies and is constructed with a COG dielectric. Operation is across -55 to +125°C and it has a ±5% tolerance. Packaging is a 2.5mm tall 3.2 x 2.5mm ...

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. ...
