UBT1E221MPD

The UBT1E221MPD is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 25 V rating in a compact φ10 × 12.5 mm can. It is designed for applications that require stable bulk capacitance, high ripple handling and extended operation at elevated temperatures.

With an operating temperature range of −40 °C to +125 °C, AEC‑Q200 qualification, and a 5000-hour endurance rating at 125 °C, this part addresses demanding automotive electronics use cases where temperature resilience and long-term reliability are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance at 25 °C and a rated voltage of 25 V provides bulk energy storage for decoupling and smoothing functions.
• High-Temperature Endurance — Rated for operation from −40 °C to +125 °C and specified for 5000 hours at 125 °C, enabling extended performance in hot environments.
• Ripple Current Performance — Low-frequency ripple current 455.6 mA (120 Hz) and high-frequency ripple current 680 mA (100 kHz) to support power-supply filtering under varying load conditions.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.14 (measured at 20 °C, 120 Hz) and leakage current specified at 165 µA, offering predictable dissipation and leakage behavior.
• Package & Mounting — Radial lead, can-style package (φ10 × 12.5 mm) with 5 mm lead spacing (±0.5 mm) for through‑hole assembly and flexible board placement.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant, suited for regulated automotive electronic applications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.

Typical Applications

• Automotive electronics — Designed for automobile electronic systems that require durable bulk capacitance and temperature resilience in harsh under‑hood and on‑vehicle environments.
• Power-supply smoothing — Used where stable bulk capacitance and specified ripple-handling at both low and high frequencies are needed for DC power filtering.
• High-temperature assemblies — Suited to electronic assemblies that must operate reliably at up to +125 °C for extended periods.

Unique Advantages

• Extended high-temperature life — 5000 hours rated endurance at 125 °C provides predictable long-term behavior in elevated-temperature applications.
• AEC‑Q200 qualification — Qualifies the device for automotive electronics projects that require industry-specific component screening.
• Dual-frequency ripple capability — Specified ripple current at both 120 Hz and 100 kHz supports a range of power‑supply topologies and switching frequencies.
• Compact radial package — φ10 × 12.5 mm can with 5 mm lead spacing offers a small footprint for through‑hole designs where board space is limited.
• Predictable electrical parameters — Documented tan δ and leakage current values allow for accurate thermal and leakage budgeting in system design.
• RoHS compliant — Meets environmental directive requirements for restricted substances.
