UUN1E221MNQ1MS

The UUN1E221MNQ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface mounting on high-density PC boards. It provides 220 µF capacitance at a 25 V rating and is intended for general-purpose electronic applications where higher capacitance in a compact SMD can is required.

This part operates over a wide temperature range of −55 °C to +105 °C, offers a rated lifetime of 2000 hours at 105 °C (with polarity inversion per series endurance test), and is RoHS compliant.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 25 V and ±20% tolerance for general-purpose decoupling and filtering.
• Bi-Polar Construction — Bi-polarized design suitable for circuits where polarity may reverse during operation, as defined by the UUN series endurance test procedures.
• Wide Temperature Range — Designed to operate from −55 °C to +105 °C to support applications across broad environmental conditions.
• Endurance — Rated for 2000 hours at 105 °C with the specified post-test limits on capacitance change, tan δ, and leakage current as described in the series endurance specification.
• Ripple Current Performance — Specified ripple current of 270 mA at 120 Hz and 405 mA at 100 kHz for the part; frequency coefficients for ripple current are provided by the UUN series data.
• Surface-Mount Can Package — Radial, can-style SMD package sized L: 1.35 cm × D: 1.25 cm with recommended land size of 1.28 cm × 1.28 cm for automated placement.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-density PCBs — Surface-mount can format and carrier-tape compatibility enable automated placement on densely populated board layouts.
• General-purpose Power Filtering — 220 µF capacitance and defined ripple current ratings support bulk decoupling and smoothing in general electronic circuits.
• Temperature-variable Environments — Wide operating temperature range makes the part suitable for equipment exposed to cold and hot ambient conditions.

Unique Advantages

• Higher Capacitance in a Compact SMD Can — Offers 220 µF in a chip-type can package to save board space while delivering bulk capacitance.
• Bipolar Operation — Bi-polar construction permits use in circuits where polarity inversion can occur, as covered by the series endurance procedure.
• Robust Thermal Endurance — Rated 2000 hours at 105 °C, supporting designs that require long-term stability at elevated temperatures.
• Defined Ripple Current Ratings — Published ripple current values at 120 Hz and 100 kHz allow designers to size components for real-world ripple loads.
• Surface-mount Compatibility — Designed for automatic mounting with carrier tape and a recommended land pattern for reliable SMD assembly.
• Regulatory Compliance — RoHS conformity supports use in products targeting regulated markets.
