It seems to be usual practice to put in decoupling capacitors of several different values, for example 0.1uF and 1uF (or sometimes 10uF, or 0.01uF depending on the device etc). I'm wondering if there is anything that can replace a 0.1uF/1uF combo with a single device? In particular, would a low inductance 1uF (reversed geometry, LICC, or 2T-LGA) be a suitable replacement?
I have looked at the graphs that show what happens in terms of impedance when combining multiple values, but I haven't seen a similar graph for LICC that I can compare directly.
EDIT An example of the parts that I'm looking at is:
- Taiyo Yuden JWK105BJ105MP-F 1uF, 6.3V, X5R, 0204 size
- Murata LLL153C80G105ME21 1uF, 4V, X6S, 0204 size
- Samsung CLL5X105MR3NLNC
- TDK C0510X5R0J105M030AC
Compare these with totally ordinary 0.1uF 0402 capacitor: if I'm reading the datasheets right, the LICC devices have (far) lower impedance at all frequencies 0.1-100MHz. Hmm...
