TDK Corporation presents a new series of EPCOS MKP AC capacitors for filter applications. The components of the B33331V series are designed for a rated voltage of 460 VRMS, corresponding to a peak voltage of 650 V, and cover a capacitance range from 2 µF to 50 µF. Both the cans and the tops are constructed of aluminum, making […]
Polymer capacitors deliver stability and endurance in automotive applications
KEMET introduced its first 150°C automotive KO-CAP capacitor. The T599 KO-CAP high-humidity/high-temperature performance polymer series delivers stability and endurance under harsh humidity and temperature conditions. Building on the success of the T598 series, KEMET further refined the design, materials and manufacturing to ensure T599 delivers higher stability and endurance under harsh conditions. T599 capacitors pass 1,000 hours of […]
Film capacitors for DC links handle high temperature and humidity
TDK Corporation today announced that it has extended its range of EPCOS film capacitors for DC link applications. The B3277*H series now provides types for particularly harsh environmental conditions. The robustness has been verified in a temperature, humidity, bias (THB) test at 60 °C, 95 percent relative humidity, and the rated voltage for 1000 hours. […]
Better environmental specs for dc link capacitors
TDK Corporation (TSE:6762) has extended its range of EPCOS film capacitors for DC link applications. The B3277*H series now provides types for particularly harsh environmental conditions. The robustness has been verified in a temperature, humidity, bias (THB) test at 60 °C, 95 percent relative humidity, and the rated voltage for 1000 hours. Special types are also […]
Parasitic capacitance, inductance, and displacement current
When two electrical conductors are physically close, carry a charge, and there’s a voltage potential between them, they create a virtual capacitor between them, even if the conductors are insulated. The virtual capacitor between them is known as parasitic or stray capacitance. This can happen anywhere but is most troublesome between traces on printed circuit […]
Polymer aluminum high-temp capacitors for heavy industrial and stressful environments
Panasonic introduces the New SEK Series to their industry-leading OS-CON Aluminum-Polymer Solid Capacitor product line. The New OS-CON SEK Series is ideal for environments requiring high temperature. The New SEK Series parts can handle 125°C maximum temperature, making them an ideal choice for heavy industrial and stressful environments. The New SEK Series Through Hole Type features a ripple current range of 1.7 to 5 […]
First 3-V thin prismatic supercaps
CAP-XX today announced it has developed the industry’s first 3V thin, prismatic supercapacitors. The company will deploy its 3V technology first in thin prismatic form to meet demand for small, inexpensive, energy-efficient power solutions for thin wearables, key FOBs and other IoT devices. CAP-XX will then integrate the 3V technology into its larger prismatic supercapacitors, automotive […]
Tantalum capacitors for filtering, hold-up, and charging circuits offer low DCL values
AVX Corporation has released the new T4Z Medical Series HRC4000 medical-grade tantalum capacitors. Designed to replace commercial capacitors in the filtering, hold-up, and charging circuits of non-critical medical devices that require high-reliability and strict change control, including: implantable, non-life-sustaining devices, such as heart monitors, neurostimulators, insulin pumps, and temporary cardiac monitors; external, life-sustaining devices, such as automated […]
Compact film capacitors target use in inverter DC links
TDK Corporation presents an extremely compact EPCOS film capacitor for the DC link of inverters. With dimensions of just 40 mm x 58 mm (d x l) it offers a rated voltage of 350 V DC and a capacitance of 65 μF. This means that the capacitor, which has the order number B32320I2656J011, has a […]
Electrolytic capacitors go svelte
The traditional cylindrical packages that have characterized electrolytic caps are giving way to flat packs optimized for small spaces. Mario Dipietro, Flatpack Div., Cornell Dubilier Electronics, Inc. The first reported developments of electrolytic “condensers” were in the 1880s, with significant advances in the mid 1920s. In 1948, etched-foil technology developed by Illinois Condenser (today’s Illinois […]
