Solid Tantalum Capacitors Withstand Harsh Environment up to 200 Degrees C

 

The THJ 2000 SMD Series from AVX Corporation designates new solid tantalum capacitors that can deliver 1000 hours of continuous operation at 200 degrees C with derating. The capacitors are initially available in two E-size cases: the E 220 µF rated at 10 V for 3-V rail application at 200 degrees C and the E 100 µF rated at 16 V for 5-V rail application at 200 degrees C. These capacitors feature a small surface mount package that lends itself to fast pick-and-place assembly techniques and a negative temperature coefficient that ensures that no destructive localized heating occurs within the device. Gold-plated termination for hybrid assembly is provided as conventional tin/tin-lead finished terminations have melting points too low for reliability at such high temperatures. The devices have been crafted to perform reliably in harsh applications such oil and gas drilling, aerospace, defense, and automotive. For additional information on these RoHS-compliant devices, see the AVX website.
