138D Wet Tantalum Capacitors Sintered Anode TANTALEX� Capacitors Hermetically-Sealed with True Glass-to-Tantalum Seal

FEATURES

Improved reliability through the use of a glass-to-tantalum true hermetic anode seal is the prime feature of the Type 138D sintered anode TANTALEX� capacitor. This construction offers outstanding resistance to thermal shock. Model 138D is the commercial equivalents of Tansitor Styles WT, UWT, Mallory-NACC Styles TLX, TXX and Military Styles CL67, CLR65, and CLR69, designed to meet the performance requirements of Military Specification MIL-PRF39006/09/21. Capacitors in accordance with military specifications should be ordered by their military part numbers. Following the life test: 1. DCL shall not exceed 125% of the original requirement. 2. The ESR shall not exceed 200% of the initial requirement. 3. Change in capacitance value shall not exceed the percentages below. a) 6WVDC Units: 25% of initial measurement. b) 8WVDC and 10WVDC Units: 20% of initial measurement. c) 15WVDC Units: 15% of initial measurement. d) 20WVDC and above: 10% of initial measurement.

Operating Temperature: + 85�C and with voltage derating to two-thirds the + 85�C rating + 125�C. Use of Type 138D capacitors for high temperature applications is recommended. Capacitance Tolerance: � 20% standard. available as special. DC Leakage Current (DCL Max.): + 85�C and + 125�C: Leakage current shall not exceed the values listed in the Standard Ratings Tables. Life Test: Capacitors are capable of withstanding a 2000 hour life test at a temperature 125�C at the applicable rated DC working voltage.
