This document is the product manual of T409/T419/T429 series tantalum surface mount capacitors, which introduces the product features and characteristics, including rated voltage, rated capacitance, size, and packaging type
The T409/T419/T429 series are military‑qualified Tantalum Surface Mount Capacitors offered in nine case sizes (A‑X). They feature high‑grade COTS capacitance values, multiple termination finishes, and are qualified to MIL‑PRF‑55365/4 & /11. The series supports operating temperatures from –55 °C to +125 °C and offers various reliability levels.
The bulletin lists detailed mechanical dimensions, electrical parameters such as voltage rating, capacitance tolerance, ESR, and DC leakage, as well as ordering information, tape‑and‑reel packaging dimensions, and surge current designators for each case size and voltage grade.
