UUN1C102MNQ1MS

The UUN1C102MNQ1MS from Nichicon is a chip-type, bi-polarized aluminum electrolytic capacitor offering 1 mF capacitance at a 16 V rating in a surface-mount radial can package. It is designed for mounting on high-density PC boards and provides high capacitance in an SMD-compatible form factor.

With a wide operating temperature range from −55°C to +105°C and RoHS compliance, this capacitor suits general-purpose applications that require compact energy storage, AC-capable decoupling, and reliable performance across varied ambient conditions.

Key Features

• Capacitance & Voltage — 1 mF (1000 µF) rated at 16 V, with capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Bi-Polarized Design — Bipolar polarity construction enables use in AC-coupled circuits and applications where polarity inversion may occur.
• Package & Mounting — Chip-type radial can configured for surface-mount on high-density PC boards; compatible with automatic mounting from carrier tape.
• Temperature Range & Endurance — Operates from −55°C to +105°C. Endurance tested with rated voltage applied for 2000 hours at 105°C (polarity inverted every 250 hours), with capacitance change within ±20% after test.
• Electrical Performance — Ripple current capability of 670 mA at 120 Hz and 770.5 mA at 10 kHz. Leakage current specification after 1 minute: not more than 0.03 C V (µA). Tangent of loss angle (tan δ) at 16 V is max. 0.18 (120 Hz, 20°C).
• Low‑Temperature Stability — Impedance ratios for 16 V parts: Z(−25°C)/Z(+20°C) = 3 and Z(−40°C)/Z(+20°C) = 6, supporting operation in cold environments.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).
• Mechanical Dimensions — Body size L: 1.65 × D: 1.8 cm with a seated height maximum of 1.65 cm; recommended surface-mount land size 1.83 × 1.83 cm.

Typical Applications

• General-purpose power smoothing — Bulk decoupling and smoothing on surface-mount PCBs where high capacitance in a compact SMD can is required.
• AC-coupled signal paths — Bi-polarized construction supports applications with polarity reversals or AC coupling without polarity constraints.
• High-density board designs — Designed for surface mounting on high-density PC boards and compatible with automatic carrier-tape mounting for volume assembly.

Unique Advantages

• High bulk capacitance in SMD form — 1 mF capacity provides substantial energy storage while remaining suitable for surface-mount assembly.
• Bipolar flexibility — Eliminates the need for strict polarity orientation in AC-coupled or polarity-uncertain circuits.
• Wide operating temperature — Rated from −55°C to +105°C to handle a broad range of ambient conditions.
• Validated endurance — 2000-hour endurance at 105°C with defined pass/fail limits for capacitance, tan δ and leakage current provides data for reliability planning.
• Measurable ripple performance — Specified ripple current values at both 120 Hz and 10 kHz enable accurate thermal and ripple budgeting in power designs.
• RoHS compliance — Meets current RoHS directive requirements for environmentally restricted substances.
