UUN1E221MNJ1MS

The UUN1E221MNJ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. It delivers 220 µF at 25 V in a compact SMD can package and is intended for general-purpose electronic applications where a non-polarized capacitor and higher capacitance are required.

Key value propositions include a wide operating temperature range (−55 °C to +105 °C), RoHS compliance, and form-factor compatibility with automatic mounting using carrier tape, making it suitable for manufacturing environments that demand reliable, repeatable surface-mount assembly.

Key Features

• Capacitance & Voltage — 220 µF capacitance rated at 25 V for applications needing higher stored charge in a compact SMD can.
• Bi-Polar Construction — Bi-polarized design enables operation where polarity may invert, useful for AC-coupling or circuits without a fixed DC polarity.
• Temperature Range & Endurance — Specified for operation from −55 °C to +105 °C with an endurance rating of 2000 hours at 105 °C (polarity inverted every 250 hours).
• Ripple Current Capability — Rated ripple: 270 mA at 120 Hz and 405 mA at 10 kHz; frequency coefficients are provided in the UUN series datasheet so designers can size margins by frequency.
• Leakage & Loss Characteristics — Leakage current specification: after 1 minute at rated voltage and 20 °C, leakage ≤ 0.03CV (µA); tan δ (loss tangent) at 25 V is specified (max. 0.16 at 120 Hz, 20 °C).
• SMD Can Package & PCB Land — Radial, can-style SMD package with body dimensions L: 13.5 mm × D: 12.5 mm and recommended PCB land size 12.8 mm × 12.8 mm for automated placement.
• Manufacturing Friendly — Designed for automatic mounting with carrier tape and marking via black print on the case top for traceability on the production line.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for materials compliance in regulated markets.

Typical Applications

• General-purpose SMD circuits — Provides higher capacitance in a surface-mount can for space-constrained board designs that require reliable bulk or decoupling capacitance.
• AC-coupling and bipolar circuits — Bi-polarized construction supports circuits where voltage polarity can reverse or where non-polarized capacitance is needed.
• Industrial and commercial electronics — Suitable for assemblies operating across a wide ambient range (−55 °C to +105 °C) and for products requiring automated placement.

Unique Advantages

• Higher capacitance in a compact SMD can: 220 µF at 25 V provides substantial stored energy while maintaining a small board footprint (13.5 mm × 12.5 mm).
• Bi‑polarized flexibility: Allows use in circuits without a fixed polarity and supports polarity inversion during endurance testing, increasing design versatility.
• Wide temperature operation: Rated from −55 °C to +105 °C, enabling deployment across harsh thermal environments.
• Validated endurance: Specified 2000 hours at 105 °C with defined limits for capacitance change, tan δ, and leakage current, supporting reliable long-term performance.
• Assembly and production efficiency: Designed for automatic mounting with carrier tape and a standard PCB land pattern to simplify pick-and-place integration.
• Clear electrical specifications: Provided ripple current ratings at 120 Hz and 10 kHz plus measurable leakage and tan δ limits for predictable circuit design.
