UUN1E102MNJ1MS

The UUN1E102MNJ1MS is a Nichicon UUN-series chip-type aluminum electrolytic capacitor offering 1 mF capacitance at a 25 V rating. It is a bi-polarized, surface-mount device designed for use on high-density PC boards and automatic component placement.

Key attributes include a wide operating temperature range of −55°C to +105°C, RoHS compliance, and endurance tested performance up to 2000 hours at 105°C, making it suited to general-purpose SMD applications that require higher capacitance in a compact package.

Key Features

• Capacitance & Voltage — 1 mF (1000 µF) rated at 25 V, with tolerance ±20% for predictable energy storage and decoupling performance.
• Bi-polarized Construction — Bi-polar design suitable for applications that benefit from polarity-neutral operation; endurance testing includes polarity inversion during life testing.
• Wide Temperature Range — Specified operating range of −55°C to +105°C to support designs that require thermal robustness.
• Endurance — Rated for 2000 hours at 105°C with defined limits on capacitance change, tan δ, and leakage current after the test.
• Ripple Current Performance — Specified ripple current of 780 mA at 120 Hz and 897 mA at 10 kHz to support AC and ripple-handling needs within the device’s ratings.
• Surface-Mount, Tape-Fed Packaging — Chip-type SMD (radial can) package designed for placement on high-density PC boards and compatibility with carrier-tape automatic mounting.
• Electrical Losses — Tangent of loss angle (tan δ) for 25 V parts: max 0.16 (measured at 120 Hz, 20°C), allowing assessment of ESR-related losses.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose SMD circuits — Bulk capacitance and decoupling on high-density printed circuit boards where surface-mount placement is required.
• Automatic assembly workflows — Carrier-tape compatible packaging supports automated pick-and-place production.
• Wide-temperature designs — Circuits that must operate reliably from −55°C to +105°C can leverage the part’s specified temperature range and endurance.

Unique Advantages

• High capacitance in a chip package — Provides 1 mF in an SMD, chip-type aluminum electrolytic form factor for space-efficient energy storage.
• Bi-polarized flexibility — Bi-polar construction and endurance testing with polarity inversion support applications where polarity conditions may vary.
• Thermal endurance — 2000-hour qualification at 105°C gives a measurable reliability baseline for high-temperature applications.
• Defined ripple handling — Published ripple current figures at 120 Hz and 10 kHz enable targeted thermal and ripple budgeting in power designs.
• Manufacturing-ready package — Designed for surface mounting on high-density PCBs and tape-feed automatic placement to streamline production.
• Regulatory compliance — RoHS conformity supports environmental and regulatory requirements for many commercial products.
