Automotive/commercial ESD-rated ceramic caps come in 0603 EIA case size
KEMET, a leading global supplier of electronic components, has introduced electrostatic discharge (ESD) rated ceramic capacitors in small 0603 EIA case size (metric 1608), providing designers a choice of either X7R or C0G dielectric for circuits requiring Class-II or Class-I stability and noise performance. Automotive and commercial grades are available, and a special ordering code […]
Ultra-Thin Supercaps deliver 35 mF in a 20 x 20 x 0.4-mm package
Murata Americas today introduced its DMH series, a new lineup of supercapacitors with a thickness of 0.4mm, a μF order capacitance, low ESR, and the capability to output instantaneous power. The product line delivers a solution to devices with limited space that are challenged by power consumption issues since its slim package can be mounted in underutilized space. Further, the DMH can […]
EMI suppression capacitors rated for 350 V AC
TDK Corporation presents a new series of robust EPCOS MKP X2 capacitors for EMI suppression. Compared with conventional X2 capacitors designed for rated voltages of 305 V AC, these new components offer a higher rated voltage of 350 V AC. This makes them suitable for EMI suppression in input filters – specifically for applications on […]
Polymer chip caps target dc-dc converter apps with extended temperature and voltage range
AVX Corporation has extended and upgraded its TCR Series professional conductive polymer chip capacitors with new case sizes, capacitance values, and voltage ratings, a higher maximum operating temperature, enhanced performance capabilities in humid environments, MIL-STD-202 mechanical shock and vibration qualification, and improved reliability. Based on AVX’s robust conductive polymer electrode technology — the materials, construction, and […]
When to use supercapacitors
in battery applications
Author: Rutronik Electronics staff As supercapacitors, or electric double-layer capacitors (EDLCs), become more and more widely used, they are increasingly looked at as replacements for batteries. However, in many cases a 1:1 exchange is impractical or even impossible. Nevertheless, supercaps have their place. Batteries and supercaps are based on completely different energy storage methods. Looking […]
MLCC capacitors target EV charging, high-rel timing circuits
Automotive-grade soft-termination and MEGACAP Type MLCCs combine the low relative permittivity of the C0G dielectric with rated capacitance values up to 300 nF and enable MLCCs to be used where reliability is required. Their rated voltages range from 50 V to 3 kV. Developed by TDK Corp., the new MLCCs feature high capacitance stability at […]
