UBY1K621MHL

The UBY1K621MHL is an aluminum electrolytic capacitor in a radial‑lead can, offering 620 µF capacitance at a rated voltage of 80 V. Engineered for high‑temperature operation and high ripple current, this part is part of Nichicon’s UBY series and is intended for demanding power applications.

Key attributes include a wide operating temperature range of −40 °C to 135 °C, AEC‑Q200 qualification, RoHS compliance, and long endurance performance at elevated temperature, making it suitable for control and power circuits that require robust thermal and ripple handling.

Key Features

• Capacitance & Voltage — 620 µF nominal capacitance with ±20% tolerance and an 80 V rated voltage for higher‑voltage power rails.
• High Temperature Endurance — Designed for operation from −40 °C to 135 °C with an endurance rating of 2000 hours at 135 °C for 63–100 V parts.
• High Ripple Current — Supports 1.485 A ripple current at 120 Hz (low frequency) and 2.97 A at 100 kHz (high frequency), enabling reliable filtering under heavy AC stress.
• Low ESR — Equivalent series resistance of 38 mΩ at 100 kHz, helping to reduce losses and heating in high‑frequency applications.
• Leakage Current — Specified leakage current of 1488 µA to characterize standby losses under rated voltage.
• Radial, Through‑Hole Package — Compact can dimensions φ12.5 × 35.5 mm with 5.0 mm lead spacing and radial lead mounting for robust mechanical and electrical connections.
• Automotive Grade & Compliance — AEC‑Q200 qualified and RoHS compliant for use in regulated and automotive environments.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible assembly handling.

Typical Applications

• Automotive control circuits — Suited for systems such as electric power steering and direct injection engine drive where high temperature and high ripple capacity are required.
• High‑voltage power rails — Provides smoothing and decoupling on 80 V rails thanks to its combination of capacitance, low ESR, and high ripple‑current capability.
• Power electronics and industrial controls — Appropriate for power supply filtering and energy buffering in controllers that operate at elevated temperatures.

Unique Advantages

• Designed for sustained high‑temperature use — Rated to operate at up to 135 °C with an endurance specification that supports long life under thermal stress.
• Handles substantial ripple currents — Distinct low‑ and high‑frequency ripple ratings reduce the need for oversized capacitors in high‑stress power stages.
• Low power loss in AC conditions — 38 mΩ ESR at 100 kHz minimizes dissipation and improves thermal performance in switching environments.
• AEC‑Q200 qualification — Provides an added level of reliability qualification for applications targeting automotive and mission‑critical systems.
• Compact radial package — φ12.5 × 35.5 mm can with 5 mm lead spacing delivers a high capacitance density in a space‑efficient through‑hole form factor.
