UPW1A220MDD

The UPW1A220MDD is a miniature aluminum electrolytic capacitor from the UPW series designed for low impedance and high reliability in switching power supply applications. It is a polarized, radial‑lead can packaged capacitor tailored for compact board layouts and high‑frequency ripple environments.

Engineered for demanding temperature and lifetime conditions, this part is rated for operation from −55 °C to +105 °C, carries an AEC‑Q200 rating, and is specified with a 2,000‑hour life at 105 °C, making it suitable for applications that require robust, durable power filtering.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance for stable DC filtering.
• Low‑impedance, high‑frequency performance — Specified ripple current of 54 mA at 120 Hz and 180 mA at 10 kHz to support switching converter decoupling and high‑frequency smoothing.
• AEC‑Q200 qualification — Meets AEC‑Q200 requirements as specified in the product data for automotive applications.
• Wide temperature range and proven lifetime — Operates from −55 °C to +105 °C with a rated lifetime of 2,000 hours at 105 °C.
• Compact radial can package — Radial lead mounting with 2 mm lead spacing in a compact 11 mm × 5 mm footprint (L × D) and a seated height of 11 mm maximum for space‑constrained designs.
• Polarized design — Intended for DC power rail filtering and bulk decoupling in polarized circuits.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing in compact DC‑DC converters and switch‑mode power supplies.
• Automotive Electronics — Power decoupling and filtering in automotive control modules where AEC‑Q200 qualification is required.
• DC‑DC Converters — Local energy storage and ripple suppression for point‑of‑load converters operating at high switching frequencies.
• High‑frequency Power Circuits — Decoupling in circuits that require reliable performance at frequencies up to and beyond 10 kHz, supported by specified high‑frequency ripple current.

Unique Advantages

• Space‑efficient form factor — Small L × D footprint and radial lead package simplify placement in compact power modules and dense PCBs.
• Designed for high‑frequency ripple — Measured ripple current ratings at 120 Hz and 10 kHz provide predictable thermal and performance behavior in switching environments.
• Automotive‑grade reliability — AEC‑Q200 rating supports use in applications demanding established component qualification.
• Wide operational temperature — −55 °C to +105 °C range and a defined 2,000‑hour life at 105 °C deliver predictable lifetime performance in harsher environments.
• Radial lead robustness — Can‑style radial mounting offers mechanical durability for through‑hole assembly and serviceability.
