ESR and ripple — the decoupling trade-off
The TAJA104K035RNJV: The 24 Ohm ESR at 100 kHz is the dominant loss term in a decoupling or filtering application. At 0.1 µF and 35 V, this part is suited for low-frequency bypass or timing circuits where the ESR does not dominate the impedance — not for high-ripple-current bulk decoupling where a lower-ESR tantalum or ceramic would be a better fit.
Temperature range and lifetime ceiling
Rated -55°C to 125°C, the TAJA104K035RNJV covers military and industrial temperature bands — avionics, downhole instrumentation, and outdoor telecom gear all fall within this envelope.
Package and footprint — 1206 case
The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm. The size code A footprint is standard across the TAJ series — the same land pattern serves multiple capacitance/voltage combinations, simplifying BOM consolidation.
