Auto Apps Welcome Shock-, Vibration-Resistant Aluminum Electrolytic Caps

Nov. 29, 2004

New aluminum electrolytic capacitors in Epcos AG's B41605 and B41607 large-size series have their sights on automotive applications. They're distinguished by high vibrational strength that conforms to the IEC 60068-2-6 Test Fc standard. They also...

Leakage current measures 0.006 mA (for five minutes at a temperature of 20°C). Self-inductance for the B41605 and B41607 is rated at 10 and 15 nH, respectively. Thanks to their special corrugated design, they can pass all vibration tests up to 30 g and 2 kHz, even after prolonged thermal stress over 2000 hours at 125°C. Designs with vibration strength up to 40 g are available upon request.

Maximum operating voltages range from 25 to 63 V. Capacitance value ranges from 1500 to 6800 mF (B41605) and 800 to 3300 mF (B41607), with a capacitance tolerance of ±20%. The capacitors are specified to operate for a maximum continuous operating temperature of 150°C. In addition, ripple current capability is quite high, reaching 13 A at 10 kHz and 105°C. At this temperature, the components attain a service life of 20,000 hours.

These capacitors are available with snap-in terminals and terminal wires suited for welding and soldering. Orders may be placed immediately. Price depends on quantity. For example, Part # B41607 A8118 M002, an 1100-mF 63-V capacitor with a 25-mm diameter and a 40-mm length, would cost $2.95 each in large-volume orders.
