How can high temperature polymer chip capacitors be used in automotive products?
Polymer capacitors, or more precisely polymer electrolytic capacitors, are electrolytic capacitors (e-caps) with solid conductive polymer electrolytes.
High temperature gauge grade polymer chip capacitor, with rated operating temperature up to 150 C, can maintain stability for 1,000 hours at 85 C, 85% relative humidity and rated voltage.
Gauge-grade polymer capacitors, new TCO series chip capacitors will be manufactured in IATF-16949 certified facilities with a robust J-lead structure. The structure includes tantalum anode, tantalum pentoxide (Ta2O5) dielectric, and conductive polymer electrodes that exhibit a benign failure mode in the recommended operating environment. High temperature vehicle gauge-grade polymer chip capacitors can also produce low DCL (0.1C V) with 1% reliability per 1000 hours at 85 degree C and rated voltage (0.1/V series impedance and 60% confidence). They are ideal for high temperature, low power or medium power automotive, industrial and telecommunication applications.
The high-temperature gauge-grade polymer chip capacitor can achieve a tolerance of 10 F +20%, a maximum of 50 A DCL at 105 C, a maximum ESR (equivalent series resistance) of 150 mC at 100 kHz, and an operating temperature of -55 C to +150 C. In addition, the high temperature gauge grade polymer chip capacitor is also lead-free and can withstand three reflux soldering cycles at 260 degree C.
Ideal applications for high temperature gauge-grade polymer chip capacitors include automotive cab control, information entertainment and comfort systems. Car body electronic equipment for managing safety, power management and diagnostic systems; And after-sales electronic products, such as driving recorders, radar detectors, navigation systems, subwoofers, amplifiers and pillow monitors; And DC/DC converters and coupling/decoupling circuits in industrial and telecommunication equipment.
