This combination fits low-voltage supply rails — 3.3 V, 2.5 V, or 1.8 V — where the 4 V rating provides headroom against startup overshoot and ripple. The 1411 (3528 Metric) case, size code B, measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max.
At 125°C, the rated voltage should be derated per standard tantalum practice — typically 50% of the 4 V rating for reliable operation under bias. The molded case construction handles the thermal cycling without cracking the dielectric.
Price comparison is critical for BOM cost estimation and sourcing decisions.
Sourcing buyers need immediate availability to avoid production delays.
Design engineers need datasheet to validate electrical and mechanical specifications.
Cross-reference helps find substitutes when the exact part is unavailable or obsolete.
Brokers and long-term buyers need to know if the part is EOL or still active.
Maintenance techs and engineers need to confirm suitability for specific applications.
