UBT1J221MHD

The UBT1J221MHD is a polarized aluminum electrolytic capacitor in a radial‑lead can, offering 220 µF capacitance at a 63 V rating. It is designed for applications requiring elevated temperature endurance and validated reliability for automotive electronics.

Key value comes from its high operating temperature range (−40 °C to 125 °C), AEC‑Q200 rating, and a rated endurance of 5000 hours at 125 °C for this package size, making it suitable for sustained high‑temperature use in demanding environments. Note: this part is currently listed as End Of Life.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with tolerance of −20% to +20% at 63 V rated voltage.
• High‑temperature endurance — Rated for operation from −40 °C to 125 °C with a specified lifetime of 5000 hours at 125 °C for this part.
• Ripple current capability — Low‑frequency ripple current: 703.5 mA at 120 Hz; high‑frequency ripple current: 1.05 A at 100 kHz, supporting robust filtering and decoupling under ripple load.
• Low dissipation factor — tan δ of 0.10 measured at 20 °C, 120 Hz, indicating controlled loss for stable performance.
• Leakage current — Specified leakage current of 415.8 µA at rated conditions to aid in predictable bias behavior.
• Mechanical & packaging — Radial lead can, size φ12.5 × 20 mm (D × L), lead spacing 5.0 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Automotive qualification & compliance — AEC‑Q200 rated and RoHS compliant for regulated manufacturing environments and automotive system use.

Typical Applications

• Automotive electronics power rails — Filtering and bulk decoupling where high temperature endurance and AEC‑Q200 qualification are required.
• ECU and control modules — Energy buffering and ripple suppression in electronic control units operating up to 125 °C.
• Power supply smoothing — Local bulk capacitance on DC rails in high‑temperature automotive subsystems.

Unique Advantages

• Engineered for high ambient temperatures — Specified to operate up to 125 °C with a 5000‑hour endurance rating at that temperature, enabling longer service life in hot environments.
• Automotive‑grade reliability — AEC‑Q200 qualification supports use in automotive applications that demand validated component reliability.
• Defined ripple handling — Explicit low‑ and high‑frequency ripple current specifications (703.5 mA at 120 Hz and 1.05 A at 100 kHz) help designers manage thermal and ripple stress margins.
• Compact radial can — φ12.5 × 20 mm package with 5 mm lead spacing provides a space‑efficient solution for through‑hole assemblies.
• Regulatory readiness — RoHS compliance simplifies integration into regulated production processes.
