UWZ1V100MCL1GB

The UWZ1V100MCL1GB is a chip-type aluminum electrolytic capacitor in Nichicon’s UWZ series, designed for surface-mount assembly and automated board mounting. It provides 10 µF capacitance at a 35 V rated voltage, in a compact radial can SMD package sized L: 5.4 × D: 5 mm (surface-mount land 5.3 × 5.3 mm).

Targeted at demanding electronics, this capacitor combines wide operating temperature performance (–55 °C to +105 °C), AEC‑Q200 qualification, RoHS compliance, and compatibility with 260 °C peak reflow soldering to support robust, high-reliability designs in automotive and industrial applications.

Key Features

• Electrical Specification — 10 µF capacitance with ±20% tolerance and 35 V rated voltage for general decoupling, smoothing and energy-storage uses.
• Polarized Aluminum Electrolytic — Polar construction appropriate for power rail decoupling and bulk capacitance on DC circuits.
• Wide Temperature Range — Operating range from –55 °C to +105 °C to maintain performance across extreme ambient conditions.
• High-Temperature Reflow Compatible — Designed to correspond with 260 °C peak reflow soldering; recommended reflow condition: 260 °C peak for 5 s, and 230 °C over 60 s (two passes for most sizes).
• Package and Mounting — Chip-type radial can SMD suitable for automatic mounting machines fed with carrier tape; surface-mount land size 5.3 × 5.3 mm.
• Reliability and Endurance — AEC‑Q200 qualified with rated lifetime of 1000 hours at 105 °C; endurance capacitance change within ±20% (for rated voltages ≥20 V) after the test.
• Leakage and Loss Characteristics — Leakage current specified as not more than 0.01CV or 3 µA (whichever is greater) after 2 minutes at 20 °C; tan δ (loss) for 35 V rated parts is specified (0.14 max at 120 Hz, 20 °C).
• Ripple Current Ratings — Low-frequency ripple: 25 mA at 120 Hz; high-frequency ripple: 37.5 mA at 10 kHz.
• Environmental Compliance — RoHS compliant (2011/65/EU and EU 2015/863).

Typical Applications

• Automotive Electronic Control Units — Bulk decoupling and smoothing on 12 V/24 V rails in AEC‑Q200 qualified modules and control electronics.
• Power Supply Modules — DC–DC converter output filtering and energy storage where compact SMD capacitors are required.
• Industrial Controls — Capacitance for motor drives, sensor interfaces and power distribution circuits exposed to wide temperature ranges.
• Automated Assembly Lines — Designed for pick-and-place and tape-fed mounting, simplifying high-volume production flows.

Unique Advantages

• Automotive-Grade Reliability: AEC‑Q200 qualification provides a recognized reliability baseline for automotive and similarly demanding applications.
• High-Temperature Assembly Compatibility: 260 °C peak reflow compatibility reduces assembly constraints for modern lead-free processes.
• Wide Operating Temperature: −55 °C to +105 °C rating allows deployment across harsh environmental conditions without derating the system design.
• Compact Surface-Mount Format: Small L: 5.4 × D: 5 mm footprint and defined land pattern reduce PCB real estate while supporting automated placement.
• Documented Endurance: 1000 hours at 105 °C endurance with defined limits on capacitance change and leakage current supports long-term stability in thermal stress conditions.
• Measured Leakage and Loss Limits: Specified leakage current and tan δ values enable predictable power-loss and standby-current budgeting in system designs.
