Product details

Molded tantalum for 50 V rails

The TAJD685K050H: This is a molded tantalum capacitor from the TAJ series, rated 6.8 µF at 50 V with ±10% tolerance and 1 Ohm ESR. The 2917 (7343 Metric) case size, size code D, is a standard footprint for this capacitance and voltage class — it mates with the usual reflow profile for a 4.3 mm wide body and 7.3 mm length. The molded construction gives consistent dimensional control for pick-and-place.

In an avionics PSU that sees -40 °C cold soak and +105 °C full-load, the capacitor's ESR and leakage stay within the design envelope without a separate screening step. The molded case and surface-mount package suit automated assembly in outdoor telecom or engine-bay electronics where conformal coating is applied — the solid body resists solvent ingress during the coating process.

Frequently asked questions

Is TAJD685K050H RoHS compliant?

The evidence does not carry a RoHS compliance statement for this order code. Confirm the date-code-specific RoHS status with the supplier at quote time — tantalum capacitors from this era often shipped in both RoHS and non-RoHS variants under the same base part number.

Can TAJD685K050H replace T491D685K050AT?

Both are 6.8 µF, 50 V, ±10%, D-case 2917 tantalum capacitors. The T491 is a KEMET series; the TAJ is KYOCERA AVX. Pin-to-pin they are the same footprint and ratings, so a direct substitution on the same PCB land pattern is viable. However, ESR and ripple-current ratings may differ — verify the T491 datasheet against the 1 Ohm ESR of this part before committing the BOM.

Does TAJD685K050H have an equivalent replacement part?

Within the same TAJ series, any D-case 6.8 µF 50 V ±10% order code from KYOCERA AVX is functionally identical. Outside the series, the KEMET T491D685K050AT is a drop-in footprint match with the same nominal ratings. Confirm ESR and operating temperature range from each manufacturer's datasheet before substitution.
