UBY1J112MHL

The UBY1J112MHL is an aluminum electrolytic capacitor in a radial‑lead can designed for demanding temperature and ripple environments. It delivers 1.1 mF (1100 µF) capacitance at a 63 V rating with polarized radial leads, optimized for automotive and industrial control circuits.

Key value comes from its high ripple‑current capability, low equivalent series resistance, wide operating temperature range (–40°C to +135°C), and AEC‑Q200 qualification for applications that require proven reliability under elevated temperature and electrical stress.

Key Features

• Capacitance and Voltage — 1.1 mF (1100 µF) nominal capacitance with a 63 V rated voltage and tolerance of ±20% (-20%~20%).
• High Temperature Endurance — Rated for operation from –40°C to +135°C with an endurance specification of 2000 hours at 135°C.
• High Ripple Current — Supports 1.956 A low‑frequency ripple at 120 Hz and 3.26 A high‑frequency ripple at 100 kHz, enabling effective smoothing in high‑stress power circuits.
• Low ESR — ESR of 31 mΩ measured at 20°C/100 kHz, reducing losses and heat generation under ripple conditions.
• Leakage and Dissipation — Leakage current specified at 2079 µA and tanδ (DF) of 0.10 at 20°C/120 Hz, aiding predictable performance in biased circuits.
• Package and Mounting — Compact radial can: φ12.5 × 40 mm length, 5.0 mm lead spacing (±0.5 mm); supplied as bulk (no terminal forming) or bag packed for through‑hole assembly.
• Qualification and Compliance — AEC‑Q200 rated and RoHS compliant, targeting use in applications requiring verified component reliability and environmental compliance.

Typical Applications

• Automobile control circuits — Designed for automotive control electronics where sustained high temperature and ripple current tolerance are required.
• Electric power steering — Provides capacitance and ripple handling suited to power‑assist control modules.
• Direct injection engine drive — Supports power filtering and decoupling in fuel‑injection drive electronics operating at elevated temperatures.
• Automotive power electronics modules — Useful for DC bus smoothing and transient suppression in vehicle electronic control units.

Unique Advantages

• Designed for high ripple environments: Specified ripple currents of 1.956 A (120 Hz) and 3.26 A (100 kHz) enable reliable filtering under heavy AC stress.
• Low dissipation losses: 31 mΩ ESR at 100 kHz minimizes I²R losses and thermal buildup in tight thermal budgets.
• High‑temperature capability: −40°C to +135°C rating and 2000‑hour endurance at 135°C support long‑life operation in elevated temperature systems.
• AEC‑Q200 qualification: Provides an industry qualification level expected in automotive module design and validation flows.
• Compact radial package: φ12.5 × 40 mm can with 5 mm lead spacing offers a space‑efficient through‑hole solution for PCB assemblies.
• Supply and handling: Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.
