UBX2A680MHL

The UBX2A680MHL is a 68 µF, 100 V aluminum electrolytic capacitor in a radial-can package designed for high-temperature, heavy-duty applications. It belongs to Nichicon’s UBX series, a laminated-case family optimized for elevated operating temperatures and long endurance.

This part is targeted at automotive and industrial electronics where sustained performance at up to 150°C, reliable ripple handling and compact radial mounting are required. The UBX2A680MHL combines a high rated voltage, defined ripple-current capability and AEC-Q200 rating for duty-critical designs.

Key Features

• Capacitance and Tolerance — 68 µF nominal with ±20% tolerance (120 Hz, 20°C), providing defined energy storage for smoothing and decoupling.
• Rated Voltage — 100 V DC rating suitable for higher-voltage power rails in demanding systems.
• High-Temperature Operation — Rated to operate from −55°C to 150°C, enabling use in elevated-temperature environments.
• Long Endurance — Endurance specified as 1000 hours at 150°C (φ12.5 case), supporting long service life under high-temperature stress.
• Ripple Current Capability — Low-frequency ripple current 509.2 mA (120 Hz) and high-frequency ripple current 760 mA (100 kHz) to handle AC stress on power rails.
• Low Leakage and Loss — Leakage current specified at 204 µA and tan δ (DF) of 0.08 (20°C, 120 Hz) for predictable loss and insulation performance.
• Package & Mounting — Radial lead, can-style package with nominal size φ12.5 × 20 mm and 5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts.
• Automotive Grade — AEC-Q200 rated and designed for automotive electronics where heavy-duty service is required.
• RoHS Compliant & Packaging — Compliant with RoHS; available in bulk (no terminal forming) or bag packing to suit production handling.

Typical Applications

• Automotive Power Electronics — Smoothing and decoupling on vehicle power rails and control modules that require stable performance at elevated temperatures.
• Engine and Powertrain Modules — Energy storage and ripple filtering in modules exposed to high ambient temperatures and vibration.
• Industrial Control Equipment — Bulk decoupling and energy buffering in power supplies and motor-drive electronics operating in harsh environments.

Unique Advantages

• High-Temperature Endurance: Rated to −55°C to 150°C with 1000 h life at 150°C (φ12.5), enabling designs for thermally demanding locations.
• Defined High-Voltage Capability: 100 V rating provides margin for higher-voltage power rails without changing capacitor family.
