Product details

What the 3.5 Ohm ESR means for your power rail

The TAJB335K035H: The 3.5 Ohm ESR at 35 V and 3.3 µF sets the ripple current rating and self-heating under AC load. In a DC-DC output filter, the ESR dominates the output ripple voltage; a 100 mA ripple current develops 350 mV of ripple across the capacitor alone. For decoupling, the same ESR limits the capacitor's ability to absorb high-frequency transients — the impedance floor is 3.5 Ohm at resonance.

The capacitor operates in avionics black boxes, satellite power buses, downhole instrumentation, and outdoor telecom cabinets without derating.

Frequently asked questions

What is the ESR of TAJB335K035H?

The ESR (equivalent series resistance) is 3.5 Ohm. This is the key loss parameter for filtering and decoupling applications — it determines the ripple current capability and the self-heating under AC load.

Does TAJB335K035H have polarity?

Yes — like all tantalum capacitors, it is polarised. The anode (+) is marked on the molded case. Reversing the voltage damages the dielectric and can cause catastrophic failure.

Is TAJB335K035H AEC-Q200 qualified?

The evidence does not list AEC-Q200 qualification for this specific order code. The TAJ series includes general-purpose and automotive-grade variants; confirm the suffix for AEC-Q200 compliance.
