The TAJE477M006RNJ: This is a 470 µF tantalum capacitor rated at 6.3 V DC — the capacitance holds a 1 A load for about 470 µs before the rail drops 1 V, which is typical bulk decoupling for a 3.3 V or 1.8 V supply rail on a mixed-signal board. The ±20% tolerance means the actual capacitance at 25 °C and 0 V bias can range from 376 µF to 564 µF — account for this spread when setting the loop compensation of a switching regulator or the timing of an RC delay.
Surface-mount 2917 — footprint and layout fit
Housed in the 2917 (7343 Metric) case, 7.30 mm x 4.30 mm footprint, 4.30 mm seated height — this is the standard EIA-7343-31 size, so the land pattern matches the common tantalum footprint used across the TAJ series. Surface-mount assembly on a standard reflow profile; the molded case handles the soldering thermal shock without cracking, but store the reels dry — tantalum capacitors absorb moisture and the reflow can induce latent failures if the parts are not baked per IPC/JEDEC J-STD-033.
ESR 400 mOhm and temperature range
400 mOhm ESR at 100 kHz typical — this sets the ripple current rating and self-heating. For a 1 A ripple current, the internal power dissipation is 0.4 W; the part's thermal resistance to ambient determines whether the temperature rise stays within the 125 °C limit.
