Conductive Epoxy Attachment of Capacitors Written By: Ron Demcko | Ashley Stanziola Abstract: Compared to the vast majority, capacitor attachment via conductive epoxy is not a common technique among end-user applications. A significant amount of growth in capacitor usage has occurred in solder attachment methods. Furthermore, many publications on attachment methods focus predominantly on optimizing the multiple methods of solder component attachment. Therefore, confusion exists on the requirements needed to ensure reliable long-term attachment when using conductive epoxy material systems. This paper serves as a general introduction to conductive adhesives. It aims to assist end-users in the conductive epoxy attachment of SMT (Surface Mount Technology) components.

Passive Automotive Electronics for 48V Systems and V2X Written By: James Emerick Abstract: Two of the driving forces behind the quickly evolving automotive industry are fuel efficiency and safety. Fuel efficiency is primarily driven by a combination of regulatory requirements for reduced CO2 emissions and consumer demands for improved operational economy. While always paramount, safety has seen renewed activity due to the advancements of driver-assist and driverless technologies. The shift toward 48V subsystems and the integration of vehicle-to-everything (V2X) communication are two prime examples of significant advances in efficiency and safety, respectively. In both cases, new classes of electronic passives (capacitors, inductors, antennas, interconnect) are required to bring these technologies to mainstream products while meeting strict automotive regulatory standards.

LED Lighting Interconnects Solutions Written By: Alex Guan Abstract: Solid-state lighting (SSL) solutions based on the light-emitting diode (LED) and its organic relative (OLED) have become the standard for luminaires across a wide variety of application sectors. SSL performance with respect to luminous output, power efficiency, lifetime, and reliability is unmatched. Many of the challenges endured by early adopters, such as cooling, manufacturability, and form factor limitations, have largely been solved. By the year 2035, it is projected that 85% of all lighting installations will be solid-state (“2019 Lighting R&D Opportunities”).
AVX SCM series of cylindrical electrochemical double-layer capacitors offer excellent pulse power handling characteristics based on the combination of very high capacitance and very low ESR. They are ideal for Energy Harvesting applications such as an LPWA (Low-Power WideArea) remote sensing, location tracking or livestock monitoring, etc.. and perfectly fit the Renesas RE01 MCU to manage the energy charging at µA current and instantaneous power discharge at 800mA (peak current) for radio communication.

Advances in Capacitors for Miniature, High Reliability Electronics | Tech Chat – Ron Demcko & Mouser
Chris Anderson chats with Ron Demcko of AVX about AVX’s ultra-miniature MLCCs and their high-reliability tantalum polymer capacitors.
Active Band Switching Solutions Written By: Alessandro Beretta Abstract: Today’s new and emerging wireless applications are increasingly requiring the support of multiple frequency bands. From laptops to cellular phones to wearables, devices are expected to connect to any cellular, Bluetooth™, GSM, RFID, or other networks. These expectations present challenges when it comes to antenna design, compared to a traditional design. The simplest solution — using discrete antennas for each frequency band required in the application — requires extra physical space. But this ultimately clashes with industry trends that prefer smaller and smaller solutions while still providing more bandwidth.

Supercapacitors for Power Backup Applications Webinar | Richardson RFPD March 11th, 2021 | 2 PM EST Power backup requirements are often one of the most important design parameters that engineers spend their time on. For the wide range of applications that demand power backup, designing in proper energy needs can mean the difference of seconds or even milliseconds, and in turn saving or losing data. Traditionally, batteries were the first option for design engineers seeking power backup solutions. However, as environmental concerns and constant maintenance costs persist with batteries, alternative energy storage devices are gaining more consideration. Electric double-layer capacitors (EDLCs), commonly known as supercapacitors or ultracapacitors, are seeing the most interest among alternative devices. Supercapacitors are large energy
Five Advantages of AVX Poke-Home Connectors Written By: Raul Saucedo Abstract: The poke-home connector was originally introduced as a highly reliable solution for connecting a small number of discrete wires to a printed circuit board assembly. The wire is first stripped, and it is then inserted into the connector. Integral wire guides and an end stop assure proper positioning of the wire during insertion. Dual beam high force contacts (typically beryllium copper) provide extremely low electrical resistance and maximize wire retention. An example of a horizontal poke-home connector is shown in…
Leading-Edge AVX Technology in Film Capacitors Written By: Masato Nishikiori Abstract: With the advent of plastics in the middle of the 20th century, the film capacitor was introduced as a technological leap over traditional paper-based designs. Film capacitors use a thin plastic film as the dielectric that separates multiple metal electrodes. The electrodes are either deposited directly on the film (metallization) or are built from separate metal foils. The plastic metal sandwich is wound on a bobbin, and a terminal contact layer is deposited to connect all of the individual capacitor layers in parallel effectively.

Passive Components for GaN Based Devices Written By: Ron Demcko | Daniel West Abstract: The theoretical limits of Silicon-based device performance are fast approaching, and in some cases, already here. Therefore, IC (integrated circuit) design companies have turned their efforts into driving costs down while increasing the performance of wide band gap semiconductors such as GaN (Gallium Nitride). GaN based power and RF (Radio Frequency) devices are now available from multiple manufacturers at affordable prices due to those intensive efforts. Multiple sources have documented GaN based semiconductor performance advantages of faster speed, lower loss, and higher frequency-voltage-temperature operation. Those advantages are, in turn, enabling end systems that have enhanced performance on lower power consumption levels in smaller and lighter packages,
The History of Insulation Displacement Technology Written By: Hank Merkle Abstract: The need to physically connect pieces of metal together has been around for thousands of years. In the modern era of electronics, the physical connection requirement is compounded by the need for a low resistance electrical path. In both cases, the process of soldering has proven to be an excellent and time tested solution, with evidence dating back to 4,000 BC. Soldering two metal components together means that the joint is heated and a filler metal with a lower melting point than the constituent pieces is deposited to complete the connection.
