UUN1V221MNJ1MS

The UUN1V221MNJ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface mounting on high-density printed circuit boards. It delivers 220 µF capacitance at a 35 V rating in an SMD-compatible can package and is targeted at general-purpose electronic applications requiring higher capacitance in a compact form.

Key attributes include bi-polarized construction for wide temperature operation, RoHS compliance, and specifications that support automated assembly and long-term operation at elevated temperatures.

Key Features

• Chip-type, SMD can package — Designed for surface mounting on high-density PCBs and applicable to automatic mounting machines fed with carrier tape.
• Electrical rating — 220 µF nominal capacitance at a 35 V rated voltage with capacitance tolerance of ±20% (–20% to +20%).
• Bi-polarized construction — Bi-polarized series specified for operation across the listed temperature range and endurance test procedures with polarity inversion.
• Wide operating temperature — Rated for operation from –55 °C to +105 °C, supporting designs that must operate across a broad thermal range.
• Endurance and reliability — Specified endurance: 2000 hours at 105 °C with the rated voltage applied and polarity inverted every 250 hours; capacitance change within ±20% after test and leakage current within initial specified limits.
• Ripple current capability — Rated ripple current specified as 330 mA at 120 Hz and 495 mA at 10 kHz for the part’s capacitance and size range.
• Loss and impedance characteristics — Tangent of loss angle (tan δ) at 120 Hz, 20 °C: max 0.14 for 35 V devices; low-temperature impedance ratios documented for performance down to –40 °C.
• PCB footprint guidance — Recommended surface-mount land size provided to simplify layout for automated assembly.
• RoHS compliant — Conforms to RoHS directives specified in the product data.

Typical Applications

• General-purpose electronic circuits — Fits general-purpose designs that require higher capacitance in a chip-style aluminum electrolytic format.
• High-density surface-mount assemblies — Designed for surface mounting on high-density PCBs where automated tape-fed placement is used.
• Environments with wide temperature swings — Suitable for systems that must operate across –55 °C to +105 °C while retaining specified electrical characteristics.
• Designs requiring stable ripple handling — Provides specified ripple current performance at both low (120 Hz) and higher (10 kHz) frequencies for board-level decoupling or smoothing where applicable.

Unique Advantages

• High capacitance in an SMD can — 220 µF in a chip-type aluminum electrolytic package provides bulk capacitance without moving to through-hole components.
• Bi-polarized capability — Part of a bi-polarized series with endurance testing that includes periodic polarity inversion, supporting circuit designs that require non-polar operation characteristics.
• Wide temperature rating — Specified operation from –55 °C to +105 °C helps maintain performance across demanding thermal environments.
• Documented endurance — 2000-hour rating at 105 °C under rated voltage with defined limits on capacitance change, tan δ, and leakage current supports predictable long-term behavior.
• Assembly-ready — Designed for automatic mounting machines with carrier tape compatibility and provided land-size guidance to streamline PCB assembly.
• Compliance and manufacturability — RoHS-compliant construction aligns with regulatory requirements for many electronics supply chains.
