47 µF, 35 V — the BOM-fit check
That 35 V rating gives headroom on a 24 V rail or a 12 V bus with margin for transients — a common choice for bulk decoupling in power supplies and DC-DC converter outputs.
It can sit on an engine-bay ECU board or an outdoor base-station PSU without derating concerns at the hot end — the molded case handles the thermal cycling without cracking the dielectric.
ESR and ripple-current reality
900 mOhm ESR is a middle-of-the-road figure for a 47 µF tantalum in this case size. In a switching regulator output, that ESR contributes to the output ripple voltage — the designer should check the ripple current against the capacitor's rated ripple current (not listed here, but typically 0.5–0.8 A for this ESR band). Higher-ESR parts run warmer; if the application is a high-frequency buck converter, a low-ESR polymer or MLCC alternative may be worth cross-shopping.
Housed in the standard 2917 (7343 Metric) molded case, size code E — 7.30 mm x 4.30 mm footprint, 4.30 mm seated height. This is a common tantalum footprint shared by multiple manufacturers, so the PCB layout is vendor-agnostic.
No direct second-source equivalent is documented, but the 2917 footprint and 47 µF / 35 V rating are common enough that a cross-reference from Vishay, Kemet, or Panasonic is feasible — confirm the ESR and temperature range match before substituting.
