UBX1K101MHL

The UBX1K101MHL is a radial-lead aluminum electrolytic capacitor in Nichicon’s UBX series designed for high-temperature operation. This component provides 100 µF capacitance at an 80 V rating in a compact φ12.5 × 20 mm can with 5 mm lead spacing.

Engineered for demanding environments, the UBX1K101MHL targets automotive and other heavy-duty electronics where elevated ambient temperatures and sustained ripple currents are present. Key value comes from its extended temperature range, AEC-Q200 rating, and specified endurance at 150 °C.

Key Features

• Electrical Performance — 100 µF capacitance with ±20% tolerance (120 Hz, 20 °C) and a specified tanδ of 0.08 at 120 Hz, 20 °C, 80 V.
• Voltage Rating — Rated voltage of 80 V suitable for higher-voltage power rails and DC-link applications within its rated limits.
• High Ripple Current Capability — Low-frequency ripple current of 549.4 mA (120 Hz) and high-frequency ripple current of 820 mA (100 kHz), supporting applications with significant AC components.
• Low Leakage — Specified leakage current of 240 µA after application of rated voltage, aiding low-standby and precision circuits.
• High-Temperature Endurance — Rated for operation from −55 °C to +150 °C with an endurance life of 1000 hours at 150 °C (φ12.5 case), for prolonged performance in hot environments.
• Package and Mounting — Radial-lead, laminated case construction in a φ12.5 mm diameter can with 5 mm lead spacing; available in bulk or bag packing.
• Automotive Qualification — AEC-Q200 rated, indicating suitability for automotive electronics where this qualification is required.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Automotive Electronics — Designed for electronic control modules and vehicle subsystems that require components qualified to AEC-Q200 and capable of sustained operation at elevated temperatures.
• Power Supply Filtering — Suitable for smoothing and decoupling where specified ripple current ratings and low leakage are important.
• High-Temperature Electronics — Used in assemblies exposed to harsh thermal environments, leveraging the −55 °C to +150 °C operating range and 1000-hour endurance at 150 °C.

Unique Advantages

• High-Temperature Reliability: Operates to +150 °C with a tested 1000-hour endurance (φ12.5 case), reducing the need for frequent component replacement in hot environments.
• Automotive-Grade Qualification: AEC-Q200 rating supports deployment in automotive electronic systems requiring standardized component qualification.
• Robust Ripple Handling: Dual-frequency ripple current specifications (549.4 mA at 120 Hz; 820 mA at 100 kHz) provide clear performance expectations across typical power-system frequencies.
• Compact Radial Package: φ12.5 × 20 mm can with 5 mm lead spacing offers a small footprint for space-constrained boards while retaining substantial capacitance and voltage rating.
• Low Standby Losses: Specified leakage current of 240 µA supports designs where minimized leakage is beneficial.
• Packaging Flexibility: Available in bulk or bag packing to accommodate different assembly and inventory workflows.
