UAS2D221MHD

The UAS2D221MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UAS series. It is a radial‑lead, polarized electrolytic designed for general‑purpose electronic applications that require a 200 V rating, 220 µF capacitance and a compact can package (φ18 × 30.5 mm).

Key value propositions include a wide operating temperature range (−40 °C to 105 °C), elevated ripple current capability, and a 2000‑hour endurance specification at 105 °C—making it suited for designs that need reliable bulk capacitance and robustness under thermal and ripple stress.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 200 V DC rating and capacitance tolerance of −20% to +20%.
• Radial Lead Package — Radial lead (can) package, size φ18 × 30.5 mm with 7.5 mm lead spacing (±0.5 mm), suitable for through‑hole mounting.
• High Ripple Current — Low‑frequency ripple current 710 mA (120 Hz) and high‑frequency ripple current 1.136 A (10 kHz), supporting demanding ripple environments.
• Electrical Loss & Leakage — Specified tan δ (DF) ≤ 0.15 measured at 20 °C, 120 Hz; leakage current listed as 1860 µA.
• Wide Temperature & Endurance — Operating range −40 °C to 105 °C with endurance rated at 2000 hours at 105 °C under DC bias plus rated ripple current.
• Safety & Reliability — UAS series includes improved safety features for abnormal overvoltage conditions; pressure relief vent operates without dangerous outcomes under specified test conditions.
• Compliance & Packaging — RoHS‑compliant; available in bulk (no terminal forming) and bag packing. Product is in mass production.

Typical Applications

• General‑purpose electronic equipment — Provides bulk capacitance where a 200 V rating, 220 µF value and wide temperature range are required.
• Power supply ripple smoothing — Suited to applications that demand elevated ripple current handling thanks to specified ripple ratings at 120 Hz and higher frequencies.
• Thermally demanding environments — Components and assemblies that must withstand −40 °C to 105 °C operation and long endurance at elevated temperature.

Unique Advantages

• 200 V rating with compact footprint — Delivers high voltage capability in a miniature φ18 × 30.5 mm radial can to conserve board space.
• Designed for ripple‑heavy conditions — Explicit ripple current specifications at both low and high frequencies help designers size capacitance for real‑world ripple loads.
• Wide operating temperature and proven endurance — −40 °C to 105 °C range and 2000 h endurance at 105 °C support reliable performance in elevated temperature applications.
• Safety features for abnormal voltage — UAS series includes improved safety design and a pressure‑relief vent to mitigate hazardous failure modes under test conditions.
• RoHS compliant and production ready — Environmentally compliant and available in mass production quantities with standard packaging options.
