UBT1A221MPD

The UBT1A221MPD is a radial‑lead aluminum electrolytic capacitor designed for high‑temperature and heavy‑duty applications. It delivers 220 µF capacitance at a 10 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Targeted for demanding environments, this capacitor is specified for operation from −40°C to 125°C, carries an AEC‑Q200 rating, and offers ripple current and leakage characteristics suitable for power filtering and decoupling in automotive and industrial electronics.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance, suitable for energy storage and smoothing in low‑voltage power rails.
• High Temperature Endurance — Rated for operation from −40°C to 125°C with a rated lifetime of 2000 hours at 125°C, supporting sustained high‑temperature duty.
• Ripple Current Performance — Low‑frequency ripple current of 227.8 mA (120 Hz) and high‑frequency ripple current of 340 mA (100 kHz) for effective filtering under AC ripple load.
• Low Leakage — Specified leakage current of 66 µA for minimized standby loss and predictable leakage behavior after voltage application.
• Package & Mounting — Radial lead, can package (φ8 × 11.5 mm) with 3.5 mm lead spacing and bulk/bag packing options for through‑hole assembly and automated handling.
• Automotive Reliability — AEC‑Q200 qualified and RoHS compliant, suitable for use in automobile electronics requiring robust, qualified components.

Typical Applications

• Automotive power modules — Filtering and decoupling in control modules where operation up to 125°C and AEC‑Q200 qualification are required.
• DC‑DC converters — Output filtering and ripple suppression benefiting from the specified high‑frequency ripple current rating.
• Sensor and ECU power rails — Energy smoothing and leakage‑sensitive circuits that require low leakage current and stable capacitance over temperature.

Unique Advantages

• High‑temperature capability: Operates across −40°C to 125°C and rated for 2000 hours at 125°C, enabling reliable performance in elevated‑temperature environments.
• Automotive‑grade qualification: AEC‑Q200 rating provides documented suitability for automotive electronics demanding rigorous component qualification.
• Compact radial package: φ8 × 11.5 mm can with 3.5 mm lead spacing offers a small footprint for through‑hole layouts while maintaining sufficient capacitance.
• Effective ripple handling: Specified ripple current ratings at 120 Hz and 100 kHz support both low‑ and high‑frequency filtering needs.
• Low standby leakage: 66 µA leakage current helps minimize parasitic losses in standby or low‑power conditions.
• RoHS compliant: Meets RoHS requirements for use in regulated production environments.
