The UBT1V331MPD is a polarized aluminum electrolytic capacitor in a radial-lead can, delivering 330 µF at a rated voltage of 35 V. It is designed for applications that require compact through-hole components with high-temperature endurance and verified ripple handling.

With an operating temperature range from −40°C to +125°C, AEC‑Q200 qualification, and RoHS compliance, this capacitor targets automotive and other demanding electronics where robustness and long life are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance for bulk energy storage in compact form.
• High‑Temperature Endurance — Specified for operation from −40°C to +125°C with a rated life of 5000 hours at +125°C for the φ10 case at ≤50 V.
• Ripple Current Capability — Low-frequency ripple current of 636.5 mA at 120 Hz and high-frequency ripple current of 950 mA at 100 kHz to support both mains‑frequency and higher-frequency ripple loads.
• Low Leakage — Leakage current specified at 346.5 µA, supporting stable bias performance after voltage application.
• Radial Through‑Hole Package — φ10 × 20 mm can with 5.0 mm lead spacing (±0.5 mm), radial leads for straightforward through-hole mounting and mechanical retention.
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated environments and automotive electronics.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to accommodate different assembly workflows.

Typical Applications

• Automotive electronics — Suited for automobile electronics and other heavy‑duty systems that require components capable of +125°C operation.
• High‑temperature designs — For electronic assemblies that must operate reliably across −40°C to +125°C ambient ranges.
• Through‑hole power assemblies — Radial lead and compact φ10 can size for through‑hole boards and modules where axial/can capacitors are specified.

Unique Advantages

• Designed for sustained high temperature: Rated life of 5000 hours at +125°C (φ10, ≤50 V) provides predictable longevity in hot environments.
• Dual‑frequency ripple handling: Specified ripple currents at both 120 Hz and 100 kHz allow designers to quantify performance for low‑ and high‑frequency ripple conditions.
• Compact radial form factor: φ10 × 20 mm can with 5.0 mm lead spacing offers a small footprint for through‑hole layouts without sacrificing capacitance.
• AEC‑Q200 qualified: Meets automotive stress qualification requirements for use in automotive electronic systems that require qualified components.
• Regulatory compliance: RoHS compliant to support restricted‑substance requirements.
• Measured leakage specification: Leakage current defined (346.5 µA) for predictable bias loss and hold characteristics after voltage application.
