Specifications Summary

Vishay Sprague 195D476X0010H2T Tantalum Capacitor Applications

1️⃣ Automotive Electronics – Ensuring Reliability Under Harsh Conditions

✔ Engine Control Units (ECUs) – Provides stable capacitance in 12V/24V battery systems, crucial for sensor signal conditioning and microcontroller power integrity.
✔ Power Distribution Modules – Ideal for 48V mild-hybrid systems, offering low ESR (650mΩ) to minimize voltage drops in high-current paths.
✔ Infotainment & LED Lighting – Supports USB-PD modules and CAN bus filtering, reducing noise interference in audio/video circuits.
✔ ADAS & Radar Systems – Used in automotive camera modules where stable voltage regulation prevents flickering.

🔹 Why Tantalum? Unlike aluminum electrolytics, tantalum capacitors maintain performance in -55°C to +125°C underhood conditions.

2️⃣ Industrial & Power Electronics – Rugged Performance for Demanding Environments

✔ DC-DC Converters – Ensures high ripple current handling (350mA RMS) in buck/boost regulators, enhancing efficiency in 24V industrial power supplies.
✔ Motor Drives – Used in servo amplifiers for voltage smoothing, preventing PWM-induced noise in BLDC motor controllers.
✔ Switched-Mode Power Supplies (SMPS) – Acts as output filtering in GaN/SiC-based PSUs, reducing high-frequency switching noise.
✔ Renewable Energy Systems – Applied in solar inverters for DC-link stabilization, prolonging lifespan under thermal cycling.

🔹 Key Benefit: MnO₂ cathode ensures lower ESR than polymer tantalums, critical for high-frequency (>100kHz) power stages.

3️⃣ Consumer Electronics – Enabling Miniaturization & Efficiency

✔ Smartphones & Tablets – Used in PMIC decoupling, ensuring stable CPU/GPU voltage rails (1.8V/3.3V domains).
✔ Wearables (Smartwatches, TWS Earbuds) – Ultra-compact B-case (4mm × 2.8mm) fits space-constrained designs while delivering 47μF capacitance.
✔ Laptops & Ultrabooks – Critical for USB-C PD circuits, supporting 20V/5A power delivery with low leakage (<5µA).
✔ Gaming Consoles – Filters noise in high-speed DDR memory power rails, improving signal integrity.

🔹 Design Tip: Lower ESR vs. MLCCs reduces voltage ripple in high-dI/dt load scenarios.

4️⃣ Telecommunications – High-Frequency Stability

✔ 5G Base Stations – Used in RFPA (RF Power Amplifier) bias circuits, ensuring stable voltage under wide temperature swings.
✔ Optical Network Terminals (ONTs) – Supports PoE (Power over Ethernet) modules, providing bulk capacitance in compact footprints.
✔ Satellite Comms – Selected for LNB (Low-Noise Block) power conditioning due to resistance to thermal shock.

🔹 Advantage: Conformal coating prevents moisture ingress in outdoor telecom equipment.
