UBX1J331MHL

The UBX1J331MHL is a radial-lead aluminum electrolytic capacitor designed for demanding high-temperature environments. It offers 330 µF capacitance at a 63 V rating in a compact φ12.5 × 30.5 mm laminated-can package.

Engineered for automotive and other heavy-duty electronics, this part combines high operating temperature range, measurable ripple-handling capability, and AEC‑Q200 qualification to support reliable power filtering and decoupling in elevated-temperature systems.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance and a rated voltage of 63 V, suitable for mid-voltage power rails.
• High-Temperature Endurance — Operates across −55°C to +150°C with a lifetime rating of 1000 hours at 150°C, supporting sustained high-temperature use.
• Ripple Current Performance — Low-frequency ripple current of 783.9 mA (120 Hz) and high-frequency ripple current of 1.17 A (100 kHz) for effective smoothing under varying load conditions.
• Leakage Current — Specified leakage current of 623.7 µA, enabling predictable standby and leakage behavior in power designs.
• Package & Mounting — Radial-lead, laminated can construction with 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• Reliability & Qualification — AEC‑Q200 rated and RoHS compliant, intended for applications requiring established component-level qualification.

Typical Applications

• Automotive electronics — Suited for automobile electronics where heavy-duty service and high-temperature tolerance are indispensable.
• High-temperature power modules — Rated to +150°C with a 1000-hour endurance specification at that temperature for sustained operation in hot environments.
• Power filtering and decoupling — Provides bulk capacitance and measurable ripple current capability for smoothing and transient suppression in power subsystems.

Unique Advantages

• High-temperature capability: Continuous operation from −55°C to +150°C with a specified 1000-hour life at 150°C, reducing thermal-related redesign risk.
• Measured ripple performance: Explicit low- and high-frequency ripple current specifications (783.9 mA @120 Hz, 1.17 A @100 kHz) allow designers to match the capacitor to real workload conditions.
• Compact radial form factor: φ12.5 × 30.5 mm laminated can with standard 5.0 mm lead spacing for reliable through-hole mounting and assembly handling.
• Qualification-ready: AEC‑Q200 rating and RoHS compliance support regulated industries and designs requiring recognized component reliability.
• Production availability: Listed as mass production with bulk and bag packing options to support prototype through volume manufacturing.
