The ±10% tolerance keeps the effective capacitance in a narrow band, so the feedback loop doesn't see a wild shift from part to part. ## Temperature range and environment Full military temperature range: -55°C to +125°C. Molded case construction gives it mechanical stability during reflow and vibration. The 3.10 mm seated height (max) fits under low-profile heatsinks or in tight board stacks. Standard 2917 (7343 Metric) footprint — same pad layout as the generic D-size tantalum case. No special handling beyond standard MSL precautions for molded tantalums.","metaTitle":"KYOCERA AVX TPSD477K004R0045 Tantalum Cap, 470 µF, 4 V","metaDescription":"KYOCERA AVX TPSD477K004R0045 molded tantalum capacitor, 470 µF, 4 V, ±10%, 45 mΩ ESR, 2917 package, -55 to 125°C.
