UBT1E222MHD8

The UBT1E222MHD8 is a radial-lead aluminum electrolytic capacitor offering 2200 µF capacitance at a 25 V rating. Designed for high-temperature operation, it supports an operating range of −40 °C to +125 °C and is specified for extended life up to 10,000 hours at 125 °C.

With low impedance, high ripple-current capability and AEC‑Q200 qualification, this part addresses demanding power-filtering and energy-storage roles in temperature-challenging environments while remaining RoHS compliant.

Key Features

• Electrical Performance — 2.2 mF (2200 µF) capacitance at 25 V with ±20% tolerance; low impedance of 20 mΩ supports stable voltage behavior under load.
• Ripple Current Handling — Rated ripple current: 1.816 A at 120 Hz (low frequency) and 2.71 A at 100 kHz (high frequency), enabling effective smoothing of power rails across a range of switching frequencies.
• High-Temperature Endurance — Specified for 10,000 hours life at 125 °C (per series endurance conditions), providing long-term stability for elevated-temperature applications.
• Leakage and Polarization — Polarized aluminum electrolytic construction with a measured leakage current of 1650 µA, consistent with its rated voltage class.
• Package & Mounting — Radial-lead, can-style package with dimensions φ16 × 30.5 mm and 7.5 mm lead spacing (±0.5 mm) for through-hole PCB mounting; available in bulk or bag packing.
• Automotive Qualification & Compliance — AEC‑Q200 rated and RoHS compliant, aligning with industry requirements for regulated electronic assemblies.

Typical Applications

• Automotive Electronics — Used for power filtering and smoothing in automotive modules where operation at up to +125 °C and high ripple currents are required.
• Power Supply Filtering — Supports bulk energy storage and ripple reduction on DC rails across switching frequencies up to 100 kHz, leveraging its high ripple-current ratings and low impedance.
• Embedded Systems in Harsh Environments — Suited for electronics that demand long endurance at elevated temperatures thanks to its 10,000-hour life rating at 125 °C.

Unique Advantages

• High-temperature reliability: Rated for −40 °C to +125 °C with 10,000 hours endurance at 125 °C, reducing risk of premature degradation in hot environments.
• Wide ripple-current capability: Supports both low- and high-frequency ripple (1.816 A at 120 Hz, 2.71 A at 100 kHz), letting designers cover a broad range of power-conditioning needs with a single part.
• Low impedance: 20 mΩ impedance minimizes voltage drop under load and improves transient performance on power rails.
• Automotive-grade qualification: AEC‑Q200 rating provides a verified quality level for use in regulated automotive electronics designs.
• Compact radial-can form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing simplifies through-hole assembly and placement in constrained layouts.
