UBT1C331MPD8

The UBT1C331MPD8 is a radial-lead aluminum electrolytic capacitor offering 330 µF capacitance at 16 V with ±20% tolerance. Engineered for high-temperature, long-life applications, it delivers low impedance, defined ripple-current capability, and AEC-Q200 qualification for use in demanding automotive and industrial electronics.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 16 V with ±20% tolerance, suitable for bulk energy storage and decoupling in low-voltage power rails.
• High‑Temperature Endurance — Rated for operation from −40°C to +125°C with a specified lifetime of 5000 hours at 125°C for the φ10 × 12.5 L package size.
• Automotive Reliability — AEC‑Q200 qualified, designed for applications requiring qualification to automotive component standards.
• Low Impedance and Loss — Impedance of 100 mOhm and tan δ of 0.16 at 120 Hz (20°C) for stable performance in power-conditioning roles.
• Defined Leakage and Ripple Ratings — Leakage current of 158.4 µA and ripple-current ratings of 455.6 mA at 120 Hz (low frequency) and 680 mA at 100 kHz (high frequency).
• Radial Can Package — φ10×12.5L radial can with 5 mm lead spacing, bulk/bag packing, and mass-production availability for straightforward through-hole assembly and inventory handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive Electronics — Suited for automotive electronic modules where high-temperature endurance and AEC‑Q200 qualification are required.
• Power Supply Filtering — Acts as bulk capacitance and ripple smoothing on 16 V rails, supported by specified ripple-current ratings at both low and high frequencies.
• High-Temperature Power Modules — Designed for sustained operation up to +125°C with a 5000‑hour rated life at that temperature for the φ10×12.5L size.

Unique Advantages

• Long High‑Temperature Life: 5000 hours at +125°C (φ10×12.5L) provides predictable endurance for thermal-stressed designs.
• AEC‑Q200 Qualification: Supplies traceable automotive-grade qualification for designs targeting vehicle electronics.
• High Ripple Handling: Defined ripple-current ratings (455.6 mA @120 Hz, 680 mA @100 kHz) allow reliable DC bias plus ripple operation at elevated temperature.
• Low Impedance and Controlled Loss: 100 mOhm impedance and tan δ = 0.16 at 120 Hz help maintain voltage stability and reduce heat generation in power circuits.
• Compact Radial Form Factor: φ10×12.5L can with 5 mm lead spacing simplifies through-hole placement while keeping a small board footprint.
• Regulatory Compliance: RoHS compliant to meet environmental requirements.
