Restricted MLCC supply focuses on re-design activity
The case sizes of Multi-Layered Ceramic Capacitors (MLCC) available today are seemingly ever shrinking, which coupled with a long term reduction in manufacturing capacity for legacy commodity products and dramatically increasing manufacturer lead times is creating a supply headache for customers in Europe. In this update Adam Fletcher, Chairman of the Electronic Components Supply Network(ecsn)examines the current issues and suggests how they may ...
Five ways to mitigate PCB component availability problems
The electronics design world is by now aware that there is a very serious components shortage. Allocation and shortages hit every few years, but this one seems to be the worst in recent memory, the hardest hit seem to be ceramic capacitors, but other passives as well as a variety of connectors and silicon parts are also caught up in the shortage storm.

Space-level ESCC QPL 3009/041 X7R BME MLCCS
AVX has extended its range of space-level ESCC QPL 3009/041 X7R base metal electrode (BME) multilayer ceramic capacitors (MLCCs) — the first range of ESCC BME MLCCs fully qualified for use in European, Asian, and American space market applications — with new 0402 and 2220 case sizes.
Film capacitors provide circuit protection
Film capacitors for UPS, AC power supplies and general AC filtering applications from Dubilier Cornell are now being shipped by New Yorker Electronics. The 951C Round Axial Leaded and 953B Radial Leaded Box Metallised Polypropylene Film Capacitors offer strong performance for filtering in applications where high ripple currents are encountered and benign end-of-life failure mode is essential.
Checking twist pair relationships in short cables
Celebrating its 25th anniversary, CAMI Research, manufacturer of the CableEye automation-ready cable and harness test system, has developed the capability of checking and measuring twist pair relationships in cables as short as six feet. This feature is now standard in the model M4 low voltage continuity tester, and available as an option for HiPot (HVX-series) testers. The same circuitry allows for measuring cable length, length to break, capaci...
Considerations when comparing SiC and GaN in power applications
Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductor technologies are promising great things for the future. SiC devices in a cascode configuration enable existing systems to be easily upgraded to get the benefits of wide band-gap devices right now. By: Anup Bhalla, VP Engineering, UnitedSic.
Has the 1806 three terminal ‘C’ filter become obsolescent?
In regards to component obsolescence, Steve Hopwood, Senior Application Engineer at Knowles Precision Devices (KPD), stated: “The rate of component obsolescence has increased over the last 15 years. OCMs are discontinuing more part numbers per year for a variety of reasons, including manufacturing changes, changes in die dimensions and other technology changes.”
Component manufacturer qualified to produce MIL-PRF-123 capacitors
It has been announced that AVX is now qualified to produce and supply MIL-PRF-123 capacitors at its corporate headquarters in South Carolina. Furthermore AVX has had its M123 Series ceramic chip capacitors added to the Defense Logistics Agency’s (DLA’s) Qualified Parts List for MIL-PRF-123.
High power electronic fuse with features for safety
Sustaining up to 4A continuous current over a wide operating input voltage range of 8 to 48V, with low insertion loss thanks to its integrated low-RDS(ON) VIPower MOSFET, the STEF01 programmable electronic fuse from STMicroelectronics extends the benefits of fast acting overload protection to applications at higher power ratings.
