UBX1C331MPL

The UBX1C331MPL is a miniature radial‑lead aluminum electrolytic capacitor from Nichicon’s UBX series, specified at 330 µF and 16 V. It is a high‑reliability, high‑temperature component designed for demanding electronics where extended temperature tolerance and sustained ripple handling are required.

Key value points include operation across a wide temperature range (−55°C to +150°C), AEC‑Q200 compliance for automotive‑grade reliability, and a compact φ10 × 20 mm can with 5 mm lead spacing for easy through‑hole mounting in constrained assemblies.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 16 V with tolerance ±20% (120 Hz, 20°C).
• High Temperature Operation — Specified operating temperature from −55°C to +150°C and endurance rated for 1000 hours at 150°C, suitable for high‑temperature environments.
• Ripple Current Capability — Low‑frequency ripple current 268 mA (120 Hz) and high‑frequency ripple current 400 mA (100 kHz), enabling effective smoothing and decoupling under AC loading.
• Low Leakage — Measured leakage current of 158.4 µA, supporting low‑loss power applications where standby current matters.
• Reliability & Standards — AEC‑Q200 rated and RoHS compliant, designed for demanding, long‑life applications in regulated environments.
• Form Factor & Mounting — Radial lead, laminated can construction in a compact φ10 × 20 mm case with 5.0 mm lead spacing for through‑hole PCB mounting; available in bulk or bag packing (no terminal forming).
• Dissipation Factor — tan δ (DF) of 0.16 measured at 20°C, 120 Hz, useful for evaluating AC loss in filtering applications.

Typical Applications

• Automotive electronics — Suitable for electronic control modules and in‑vehicle systems that require components designed to withstand extended high temperatures and automotive operating conditions.
• Power supply filtering — Bulk smoothing and decoupling in DC‑DC converters and power rails where elevated ambient temperatures and sustained ripple are present.
• High‑temperature embedded systems — Use in industrial or harsh‑environment electronics that demand long endurance at elevated temperatures.

Unique Advantages

• Extended temperature capability: Rated for −55°C to +150°C and tested for 1000 hours at 150°C, enabling reliable performance in hot operating environments.
• Automotive‑grade reliability: AEC‑Q200 compliance signals suitability for applications requiring automotive reliability practices and quality control.
• Compact, serviceable package: φ10 × 20 mm radial can with 5 mm lead spacing offers a space‑efficient through‑hole solution for retrofit or new designs.
• Robust ripple handling: Specified low‑ and high‑frequency ripple currents (268 mA @ 120 Hz, 400 mA @ 100 kHz) support effective filtering across frequency ranges.
• Low leakage and defined dissipation: 158.4 µA leakage and tan δ = 0.16 (20°C, 120 Hz) provide predictable electrical behavior for power management designs.
• RoHS compliant: Meets RoHS requirements for restricted substances, simplifying regulatory considerations.
