The TAJY336M020RNJ is a molded tantalum capacitor from KYOCERA AVX's TAJ series, rated at 33 µF with a 20 V working voltage and ±20% tolerance. It comes in the standard 2917 (7343 Metric) chip package — a footprint shared across multiple manufacturers, so the PCB land pattern is interchangeable if you ever need to second-source. With an ESR of 600 mOhm, this part is suited for bulk decoupling and hold-up capacitor roles where moderate ripple current is present — think output filtering on a 12 V rail or input smoothing after a rectifier. The -55 to +125 °C operating range covers military and aerospace temperature extremes, so it can sit in an avionics power supply or a satellite's secondary-side filter without derating concerns at the cold end.
Package and footprint for PCB layout
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 2.00 mm max. The Y size code tells you the case height is the low-profile variant — useful when board-to-board clearance is tight. Surface-mount assembly on a standard FR-4 board; the molded body handles reflow soldering without cracking, but keep the peak temperature within the datasheet profile to avoid thermal shock to the tantalum element.
