Molded tantalum for space-constrained decoupling
The F381A106MMA is a 10 µF molded tantalum capacitor rated at 10 V in the compact 0603 (1608 Metric) case size. This capacitance density suits it for bulk decoupling on lower voltage rails where board real estate is at a premium.
ESR and frequency response for filtering
With an ESR of 500 mOhm at 100 kHz, this part provides moderate ripple suppression. For high-frequency decoupling, the ESR dominates impedance at lower frequencies; above that, the capacitance and ESL take over. Pair with a smaller ceramic capacitor for broadband bypass. The 1000-hour endurance at 85°C is typical for tantalum capacitors. For continuous operation near the temperature limit, derate voltage or consider a higher-temperature rated series. The operating range spans -55°C to 105°C.
For BOM planning, this part can be sourced through independent distribution. No direct second-source equivalent is listed, but the F38 series includes other capacitance and voltage combinations in the same 0603 footprint.
