Type T495
Solid Tantalum Chip Capacitors
Low ESR, High Ripple Current, Solid Tantalum Chip Capacitors
Like the T491 standard tantalum capacitors the Type T495’s
physical outline and dimensions conform to the global
standard for tantalum capacitor chips and exceed the
requirements for EIA standard 535BAAC, but performance
sets the T495 apart. The very low ESR, high ripple current
capability, capacitance stability, and ability to withstand high
inrush currents makes the T495 ideal for output filtering in
switch-mode power supplies and DC-DC converters and
in battery-stiffening filters. This capability is from unique
design and high-stress, low impedance electrical condition
ing. Reliability and thermal stability are assured by lead-
frame attachments to the tantalum pellet made by micropro
cessor-controlled welding and high temperature silver
epoxy adhesive. Standard packaging is compatible with all
tape-fed placement units and with EIA 481-1 tape and reel
specifications
