The TPSD475K050R0700: In a switching regulator output filter, the ESR dominates the output ripple voltage — 4.7 µF with 700 mOhm yields roughly 3.3 mV ripple per 100 mA of ripple current, which is acceptable for most logic supplies but marginal for sensitive analog rails.
Temperature range and case size
Capacitance change over temperature is typically +10% at -55°C and -10% at +125°C for tantalum dielectrics — the 4.7 µF nominal holds within the ±10% tolerance band across the full range. The pad layout matches the standard EIA-7343-31 pattern — no footprint adjustment needed when cross-referencing between brands.
