UBT1C331MPD

The UBT1C331MPD is a radial-leaded aluminum electrolytic capacitor offering 330 µF capacitance at a 16 V rating. Built for high-temperature operation (–40 °C to +125 °C) and long endurance, it targets demanding electronic systems that require stable capacitance and sustained ripple handling under elevated temperature stress.

Designed within the Nichicon UBT series, this part combines compact radial can packaging (φ10 × 12.5 mm) with AEC-Q200 qualification and RoHS compliance, making it suitable for automotive electronics and other heavy‑duty environments that demand long life and reliable performance.

Key Features

• Electrical Performance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C; rated voltage 16 V; tangent of loss angle (tan δ) of 0.16 (120 Hz, 20 °C).
• Ripple Current Capability — Low-frequency ripple current of 455.6 mA (120 Hz) and high-frequency ripple current of 680 mA (100 kHz), supporting applications with continuous ripple loading.
• Leakage Current — Specified leakage current of 158.4 µA, enabling predictable leakage behavior in biased circuits.
• High-Temperature Endurance — Rated for operation from –40 °C to +125 °C with a life/endurance specification of 5000 hours at +125 °C for this form factor.
• Package and Mounting — Radial lead, polarized aluminum can package (φ10 × 12.5 mm) with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Quality and Compliance — AEC-Q200 qualified and RoHS compliant, aligning with industry reliability and environmental requirements.

Typical Applications

• Automotive Electronics — Suitable for vehicle electronic modules that require high-temperature capability and extended life at +125 °C.
• Power Supply Filtering — Used where sustained ripple handling and defined leakage are needed under continuous bias at elevated temperatures.
• Heavy‑Duty Electronics — Applicable to systems and modules that demand long endurance (5000 hours at 125 °C) and predictable stability over time.

Unique Advantages

• High‑temperature reliability: Engineered for operation to +125 °C with a specified 5000‑hour endurance, enabling designs that run hot without sacrificing lifetime expectations.
• Automotive-grade qualification: AEC‑Q200 status provides a documented quality baseline for vehicle electronics and other high-reliability systems.
• Measured ripple performance: Defined low- and high-frequency ripple current ratings (455.6 mA at 120 Hz, 680 mA at 100 kHz) support predictable thermal and electrical design margins.
• Compact radial package: φ10 × 12.5 mm can in a radial-lead format offers a small footprint for board-level power decoupling where axial through-hole reliability is required.
• Clear electrical characterization: Specified tan δ and leakage current values enable accurate modeling of loss and standby behavior in power designs.
• RoHS compliant: Meets environmental directives for lead‑free manufacturing and end-product compliance.
