0.47 µF at 35 V — bulk decoupling on a 24 V rail
This TPSA474K035R6000 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated 0.47 µF at 35 V with ±10% tolerance. The 35 V rating gives headroom on a 24 V supply — the derating rule for solid tantalums (50% of rated voltage) lands at 17.5 V, so this cap is suitable for rails up to about 17 V continuous. For a 24 V bus, step down before the capacitor or move to a 50 V rated part. The 6 Ω ESR sets the ripple-current ceiling. At 100 kHz, the self-heating from ripple current is I² × ESR; a 0.47 µF cap with 6 Ω ESR handles only modest AC content — it is a bulk or bypass part, not a high-frequency filter. Use a low-ESR MLCC for decoupling above a few MHz.
1206 case — standard footprint, rework-friendly
The 1206 (3216 Metric) package measures 3.20 mm × 1.60 mm with a seated height of 1.80 mm max. This is a common footprint across tantalum and ceramic capacitor families — the land pattern matches standard reflow profiles, and the larger pad size makes hand-soldering or hot-air rework straightforward. The molded body provides good mechanical stability against board flex, but the tantalum element still requires a controlled ramp rate during reflow to avoid thermal shock. Operating temperature spans -55 to +125 °C, covering industrial and military-grade environments. The molded construction resists moisture ingress better than uncoated chips, but the part is not hermetically sealed — conformal coating over the assembly is recommended for high-humidity or condensing environments.
KYOCERA AVX continues to manufacture the TPS series, so supply continuity is stable through authorized and independent channels.
