UBY1K471MHL

The UBY1K471MHL is a high-reliability miniature aluminum electrolytic capacitor in a radial lead can. It delivers 470 µF capacitance at an 80 V rating with a compact φ16 × 20 mm package designed for demanding temperature and ripple environments.

Optimized for high ripple current and high-temperature operation, this AEC‑Q200 qualified, RoHS‑compliant part is suited for control and power electronics where long-term stability and elevated operating temperatures are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at an 80 V rated voltage with ±20% tolerance for stable bulk energy storage.
• High‑Temperature Operation — Rated for operation from −40°C to 135°C and endurance specified for 2000 hours at 135°C under rated conditions.
• High Ripple Current Capability — Low‑frequency ripple current of 955 mA (120 Hz) and high‑frequency ripple current of 1.91 A (100 kHz) to handle demanding ripple loads.
• Low ESR — ESR of 53 mΩ measured at 20°C/100 kHz for reduced loss and improved thermal performance.
• Leakage and Loss Characteristics — Specified leakage current of 1128 µA and tanδ of 0.08 (measured at 20°C, 120 Hz) to aid predictable circuit behavior.
• Packaging & Mounting — Radial lead can, size φ16 × 20 mm with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Automotive‑Grade Reliability — AEC‑Q200 qualified and designed for automotive control circuits; series documentation cites suitability for applications such as electric power steering and direct injection engine drive.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Automotive control modules — Bulk energy storage and smoothing in electronic control units where high ripple and elevated temperatures are present.
• Electric power steering systems — Handling transient currents and providing stable supply decoupling under high thermal stress.
• Direct injection engine drives — Filtering and energy buffering in engine drive circuits requiring high ripple tolerance and AEC‑Q200 qualification.

Unique Advantages

• Designed for high ripple loads — High ripple current ratings at both low and high frequencies reduce heating and improve lifetime in power‑dense circuits.
• High temperature endurance — Specified 2000‑hour endurance at 135°C supports reliability in elevated ambient conditions.
• Low ESR for efficient operation — 53 mΩ ESR at 100 kHz minimizes conduction losses and supports tighter voltage regulation.
• Automotive qualification — AEC‑Q200 rating and series recommendations for automotive control applications streamline selection for vehicle electronics designs.
• Compact radial can format — φ16 × 20 mm footprint with 7.5 mm lead spacing offers a space-efficient solution for through‑hole power designs.
• Production readiness — Listed as mass production, available in practical bulk and bag packing options for production assembly.
