UHD1A221MED

The UHD1A221MED is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHD series. It is a radial-lead, polarized capacitor rated at 220 µF and 10 V, designed for general-purpose electronic applications where compact size, high ripple handling and low impedance at higher frequencies are required.

Key performance characteristics include low loss (tanδ 0.19 at 20°C, 120 Hz), specified leakage current and both low- and high-frequency ripple current ratings, combined with an operating temperature range of −40°C to 105°C.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 10 V with a tolerance of ±20% (−20% to +20%).
• Low Loss / Impedance — Tangent of loss angle (tanδ) specified at 0.19 (measured at 20°C, 120 Hz), supporting lower loss in AC applications.
• High Ripple Handling — Rated ripple currents of 283.5 mA at 120 Hz and 405 mA at 100 kHz, enabling robust performance across low and high frequency ripple conditions.
• Leakage Current — Specified leakage current of 22 µA (measured after rated voltage applied for 2 minutes at 20°C), supporting stable DC performance.
• Temperature & Endurance — Operating temperature range −40°C to +105°C with a life/endurance rating of 2000 hours at 105°C.
• Compact Radial Package — Small can size φ6.3 × 11 mm with radial leads and 2.5 mm lead spacing (±0.5 mm), suitable for through-hole mounting and compact board layouts.
• Packaging & Compliance — Available in bulk (no terminal forming) and bag packing; RoHS compliant.

Typical Applications

• General-purpose electronic circuits — Provides 220 µF/10 V capacitance with low loss and measurable ripple capability for broad general-purpose uses.
• AC ripple suppression — High ripple current ratings at both 120 Hz and 100 kHz make this capacitor suitable where ripple handling across frequencies is required.
• Temperature-varied environments — Rated for −40°C to +105°C operation and a defined 2000 h endurance at 105°C for designs exposed to elevated operating temperatures.

Unique Advantages

• Compact footprint: φ6.3 × 11 mm can size and radial leads enable space-efficient through-hole placement in dense assemblies.
• Designed for ripple and frequency flexibility: Specified ripple currents at 120 Hz and 100 kHz, together with the UHD series’ lower high-frequency impedance characteristic, support mixed-frequency filtering tasks.
• Predictable loss characteristics: A defined tanδ (0.19 at 20°C, 120 Hz) gives designers measurable AC loss behavior for reliable circuit modeling.
• Controlled leakage: Leakage current of 22 µA supports stable DC biasing and predictable long-term behavior after initial application of rated voltage.
• Wide operating temperature: −40°C to +105°C rating provides usable performance across a broad environmental range.
• RoHS compliant packaging: Offered in bulk and bag formats and compliant with RoHS directive for regulatory alignment.
