Hybrid Aluminum-Polymer Capacitors Feature Low ESR, Wide Temp Range

Tue, 08/16/2011 - 12:08pm

Al-polymer capacitorsTecate Group announced the release of the MXCPB and MXCPT Series of aluminum-polymer hybrid construction capacitors. The new SMD series combines the low ESR of polymer capacitors with the low leakage current characteristics of aluminum electrolytic capacitor technology. Presented as highly stable when exposed to temperature fluctuations, most components notably feature operating temperatures from -55 degrees C to +135 degrees C, and load life ratings to 2,000 hours. The devices are offered in voltage options ranging from 6.3 VDC to 63 VDC, and with capacitance values from 10 µF to 560 µF. The capacitors range in size from 6.3 mm diameter x 7.7 mm long to 10 mm x 12.5 mm.

The solvent-resistant MXCPB and MXCPT Series of SMD hybrid aluminum-polymer capacitors' super-low ESR and high capacitance values enable low impedance at high frequencies to support excellent noise suppression and ripple absorption in a wide range of such consumer, industrial and automotive electronics as PC servers, networking equipment, flat-panel TVs, power supplies and inverters. In automotive applications, parts are used to boost energy efficiency in engine-management and electronic fuel-injection systems, gearbox controllers, steering aids, and in motors for windshield wipers and fans, along with oil, or water pumps.

Tecate's new MXCPB Series is available in nine capacitance values ranging from 22 µF to 560 µF and voltage options of 6.3 VDC, 10 VDC and 16 VDC. They are provided in 8 mm diameter x 10.5 mm long and 10 mm x 10.5 mm case sizes, with operating temperatures from -55 degrees C to +125 degrees C. Load life is 2,000 hours at +125 degrees C. Uniquely boasting an operating temperature range of -55 degrees C to +135 degrees C, capacitors in the MXCPT Series are offered in fifteen capacitance values ranging from 10 µF to 330 µF and in voltages of 25 VDC, 35 VDC, 40 VDC, 50 VDC and 63 VDC. These components may be ordered in 4 case sizes ranging from 6.3 mm diameter x 7.7 mm long to 10 mm x 12.5 mm. At +135 degrees C, 6.3 mm x 7.7 mm parts' load life is 1,000 hours. All other components in this series feature a 2,000 hour load life. Both series' capacitance tolerance is +/-20%. Devices are available in Pb-free and RoHS-compliant versions and supplied tape and reel.
