  • Type 271 is accomplished by development of higher purity tantalum powder and other materials and improvement of pelleting and anodizing process condition. Temperature range of continuous usage is improved from125℃ to 150℃ with specified voltage derating.
  • Moisture resistance: 85℃ 85%R.H.1000h
  • Dimensional accuracy and symmetrical terminal structure suitable for high-density mounting ensures excellent “Self-Alignment”.
  • Recommended Soldering Conditions: 320℃ for 10 seconds by reflow or flow soldering.
  • This type is especially suitable for ECU(Electronics Control Unit),Automatic Transmission and others in the engine room of automobile, and for High Reliability applications.
