Vishay Sprague model 109D tubular elastomer-sealed, sintered anode TANTALEX® capacitors are the commercial equivalents of Tansitor style WC, UWC, Mallory-NACC style TLS, TLH and the Military Style CL64 and CL65, designed to meet the performance requirements of Military Specification MIL-DTL-3965.
The 109D series are wet tantalum capacitors with a sintered anode and elastomer seal, designed for industrial, automotive and telecommunications applications where high reliability and temperature capability are required. They are available with standard tin/lead or 100 % tin (RoHS‑compliant) terminations.
The document lists performance characteristics such as operating temperature, capacitance tolerance, leakage current, ESR, and maximum voltage ratings, together with standard and extended rating tables, dimensions, and recommended packaging. Ordering information includes case codes, part numbers and RoHS compliance details.
| Operating Temperature | -55 °C to +85 °C (to +125 °C with voltage derating) |
|---|---|
| DC Leakage Current (DCL max.) | Limited to values listed in the Standard Ratings Tables at +25 °C, +85 °C, +125 °C |
| Packaging | Formed plastic trays are standard; tape and reel not recommended |
They operate from –55 °C to +85 °C, and can be used up to +125 °C with voltage derating.
