UVZ1A220MDD

The UVZ1A220MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVZ series. It provides 22 µF capacitance at a 10 V rated voltage in a compact φ5 × 11 mm can with 2 mm lead spacing, intended for general-purpose low-voltage circuits.

Key electrical characteristics include a capacitance tolerance of ±20%, tangent of loss angle (tan δ) of 0.24 at 20°C/120 Hz, low leakage current, and ripple-current ratings specified for both low and high frequency. The part is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage — 22 µF rated capacitance at 10 V, with a tolerance of -20% to 20% for predictable filtering and decoupling behavior.
• Loss and Leakage — tanδ of 0.24 measured at 20°C and 120 Hz; leakage current specified at 6.6 µA for low quiescent current impact.
• Ripple Current Ratings — Low-frequency ripple current 45 mA at 120 Hz and high-frequency ripple current 90 mA at 10 kHz to support AC ripple handling across common operating frequencies.
• Thermal and Endurance — Rated for operation from -55°C to +105°C with an endurance of 1000 hours at 105°C as specified for this part.
• Mechanical Package — Radial lead, can-style package sized φ5 × 11 mm with 2 mm lead spacing (±0.5 mm), suitable for through-hole assemblies.
• Compliance & Packing — RoHS compliant; available in Bulk (no terminal forming) or Bag packing.

Typical Applications

• Low-voltage power rail decoupling — Local smoothing for 10 V rails where a compact 22 µF radial electrolytic is required.
• General-purpose electronics — Small-form-factor consumer and industrial PCBs requiring bulk capacitance in a through-hole mount.
• Filter networks and smoothing — AC ripple attenuation at 120 Hz and higher frequencies using the specified ripple current ratings.

Unique Advantages

• Compact radial-can footprint — φ5 × 11 mm size with 2 mm lead spacing provides a small, easy-to-place through-hole option for space-constrained boards.
• Wide operating temperature — Rated from -55°C to +105°C to cover a broad range of environmental conditions.
• Measured loss and low leakage — tanδ of 0.24 and leakage current of 6.6 µA support applications sensitive to dissipation and standby currents.
• Frequency-aware ripple ratings — Separate ripple-current specs for 120 Hz and 10 kHz (45 mA and 90 mA) let designers assess performance across the frequencies common in power and signal domains.
• RoHS compliant and packaged for production — Meets RoHS requirements and is available in bulk or bag packing for prototyping or volume assembly.

Why Choose UVZ1A220MDD?

The UVZ1A220MDD offers a compact, through-hole aluminum electrolytic solution tailored for general-purpose, low-voltage designs that need 22 µF at 10 V with defined ripple-current and leakage specifications. Its wide temperature rating (-55°C to +105°C) and measured dissipation parameters make it suitable where space is limited but defined electrical behavior is required.

This part is appropriate for engineers specifying radial-lead capacitors for board-level smoothing, decoupling, and filtering in consumer and industrial equipment. RoHS compliance and standard packing options aid procurement and manufacturing planning.
