UBX1J221MHL

The UBX1J221MHL is a miniature aluminum electrolytic capacitor from Nichicon’s UBX series, configured as a radial-lead, high-reliability device. It provides 220 µF capacitance at 63 V in a compact φ12.5 × 25 mm can and is designed for demanding, high-temperature environments up to +150°C.

Targeted at automotive and other heavy-duty electronics, the UBX1J221MHL combines high temperature endurance, robust ripple-current capability, and AEC-Q200 qualification for applications requiring long-term reliability under elevated temperature and electrical stress.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• High-Temperature Capability — Specified to operate from −55°C to +150°C and rated for 1000 hours at 150°C, supporting sustained use in high-temperature environments.
• Reliability & Qualification — AEC-Q200 compliant and described in the UBX series as a “High Reliability Type,” suited for heavy-duty automobile electronics.
• Ripple Current Performance — Low-frequency ripple current of 696.8 mA at 120 Hz and high-frequency ripple capability of 1.04 A at 100 kHz to support power smoothing and transient loads.
• Leakage & Dissipation — Leakage current specified at 415.8 µA and tangent of loss angle (tan δ) of 0.1 at 20°C, 120 Hz, providing predictable electrical behavior.
• Mechanical & Mounting — Radial lead, polarized can with 5 mm lead spacing (±0.5 mm) and dimensional footprint φ12.5 × 25 mm for compact PCB integration; available in bulk or bag packing (no terminal forming).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive electronics — Designed for heavy-duty automobile electronics where high temperature endurance and long life are required.
• High-temperature power modules — Used where components must withstand sustained operation up to +150°C.
• Embedded power filtering — Provides bulk capacitance and ripple-current handling in compact, radial-lead form factors for power supply smoothing in constrained spaces.

Unique Advantages

• High-temperature endurance: Rated for operation to +150°C and supplied with 1000 hours endurance at that temperature, enabling reliable use in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 compliance provides an explicit quality baseline for designs targeting automotive electronics.
• Compact, serviceable package: φ12.5 × 25 mm radial can with 5 mm lead spacing delivers significant capacitance in a small footprint for space-constrained designs.
• Strong ripple-current capability: Defined LF and HF ripple current ratings (696.8 mA at 120 Hz; 1.04 A at 100 kHz) support smoothing and transient handling in power circuits.
• Predictable electrical characteristics: Specified tan δ (0.1 at 20°C, 120 Hz) and known leakage current (415.8 µA) help ensure stable performance during design and verification.
• RoHS compliant packaging options: Available in bulk or bag packing to match production and assembly workflows.
