Auto-Grade to Space-Grade: Building Reliable LEO Satellite Systems

As LEO satellite systems evolve from Automotive-grade expectations toward Space-grade requirements, engineers have increasingly turned to high-reliability parts that meet commercial or automotive qualifications. This is a reasonable strategy: automotive components are produced at scale, typically come with faster lead times, and have already been validated against demanding conditions such as extreme temperatures, thermal cycling, vibration, and humidity—often beyond what consumer products require.

EEF-JZ/KZ/TX/TZ Series SP-CAP™ Specialty Conductive Polymer Aluminum Electrolytic Capacitors

Panasonic has introduced its latest Surface Mount Specialty Conductive Polymer Aluminum Electrolytic Capacitors, designed for high-temperature applications that demand high endurance and large capacitance. These capacitors are compact, with heights ranging from 2.0mm to 2.3mm, and feature ultra-low ESR of 3mΩ. The EEF-TX Series offers exceptional endurance with a rating of 135℃ for 5,500 hours at a 2.0mm height, while the EEF-JZ/KZ/TZ Series provides options like 2V/560µF and 2.5V/470µF at a 2.3mm height.

There Is No Relation Between Panasonic Polymer Capacitors And Graphics Card Failures

Several tech blogs and social media outlets have reported over the past few weeks that the usage of Panasonic Polymer Capacitors (namely the POSCAPTM and SP-CAPTM series) has caused instability/crashing of certain graphics cards. Panasonic Industrial would like to denounce these false claims and present Panasonic's position on the matter.
