Extended T55 Series of Polymer Tantalum Chip Capacitors Now Available With ESR Down to 7 mΩ in the D Case; Feature Reduced Voltage Drops, Better Frequency Response, and Higher Ripple Currents Ratings Up to 5.67 A IRMS
The News:
Vishay Intertechnology today announced that the company has extended its T55 series of vPolyTan™ surface-mount polymer tantalum molded chip capacitors with new devices in the D case (EIA 7343-31) size featuring single-digit ESR values from 9 mΩ down to 7 mΩ, with values to 6 mΩ in development.
• Previously reserved for larger case sizes, the devices’ single-digit ESR values of are 3 mΩ to 5 mΩ lower than those typically found in D case devices
• Results in reduced voltage drops, better frequency response, and higher ripple current ratings
• Reduces the number of capacitors required on the PCB
• D case’s low 3.1 mm profile enables the design of thinner end products
• Provide low internal resistance for enhanced charge and discharge characteristics
