The Hi-Cap series are multilayer ceramic construction and are not polarized (unlike tantalum and electrolytic caps). In bypass and de-coupling applications you may be able to use a ceramic capacitor with 1/2 to 1/5 of the capacitance value required by a tantalum or electrolytic cap.
They come in seven temperature coefficients (TC's):
R7: X7R -55 - +125℃ +\- 15% change over that range (10/20% Capacitance tolerance (K/M))
C7: X7S -55 - +125℃ +\- 22% change over that range (10/20% Capacitance tolerance (K/M))
D7: X7T -55 - +125℃ +\- 22/33% change over that range (10/20% Capacitance tolerance (K/M))
E7: X7U -55 - +125℃ +\- 22/56% change over that range (10/20% Capacitance tolerance (K/M))
C8: X6S -55 - +105℃ +\- 22% change over that range (10/20% Capacitance tolerance (K/M))
D8: X6T -55 - +105℃ +\- 22/33% change over that range (10/20% Capacitance tolerance (K/M))
R6: X5R -55 - +85℃ +\- 15% change over that range (10/20% Capacitance tolerance (K/M))

Capacitance range: 1 uF to 100 uF (Working Voltage varies by size and Cap value).
Example: 0603, X7R, 1 uF is available in 6.3, 10, 16, and 25 VDC while 0805, X7R, 1 uF is available in 25 and 50 VDC.
