UWJ1V100MCL1GB

The UWJ1V100MCL1GB is a surface-mount aluminum electrolytic capacitor in Nichicon’s UWJ series, specified at 10 µF and 35 V. It is a compact chip-type, radial can SMD designed for automated assembly on high-density PCBs and supports 260°C peak reflow soldering.

Key technical attributes include AEC‑Q200 compliance for automotive applications, a rated operating range of −40°C to 85°C, 2000 hours load life at 85°C, low leakage and defined ripple current ratings—making it suitable for power-rail decoupling and filtering in constrained board-space designs. Note: this part is End Of Life and is typically used for repair, spare or legacy-design continuity.

Key Features

• Capacitance & tolerance — 10 µF nominal with ±20% tolerance at 20°C, 120 Hz.
• Rated voltage — 35 V DC rating for mid-voltage power rails.
• Loss factor (tan δ) — tan δ ≤ 0.12 at 20°C, 120 Hz, supporting predictable AC loss behavior.
• Leakage current — 3.5 µA (measured per standard condition), suitable for low‑leakage hold-up applications.
• Ripple current capability — 29 mA at 120 Hz (low frequency) and 43.5 mA at 10 kHz (high frequency) for power filtering duties.
• Temperature & endurance — Operating range −40°C to 85°C with a rated life of 2000 hours at 85°C.
• Automotive-grade reliability — AEC‑Q200 compliant for automotive and similarly demanding environments.
• Reflow and assembly — Chip type compatible with 260°C peak reflow; supplied in embossed carrier taping for automatic placement.
• Compact package — Case size φ5 × 5.4 mm (L: 5.4 × D: 5 mm) with recommended land 5.3 × 5.3 mm to minimize PCB footprint.
• Regulatory — RoHS compliant.

Typical Applications

• Automotive control modules — Decoupling and smoothing on mid-voltage power rails in modules qualifying to AEC‑Q200 requirements.
• DC‑DC converter output filtering — Local energy storage and ripple attenuation for compact converter outputs.
• Power-supply decoupling in industrial electronics — Space-efficient SMD solution for stabilizing supply rails on high-density boards.

Unique Advantages

• Automotive-capable construction: AEC‑Q200 compliance provides confidence in reliability for automotive and other demanding systems.
• Reflow-compatible SMD form factor: 260°C peak reflow compatibility and embossed carrier taping streamline automated assembly and reduce handling steps.
• Compact footprint: φ5 × 5.4 mm case and small recommended land size save PCB area in high-density designs.
• Defined endurance and thermal spec: 2000 hours at 85°C and −40°C to 85°C operating range enable predictable lifetime planning under rated conditions.
• Measured ripple and low leakage: Specified low- and high-frequency ripple currents plus low leakage current support stable power filtering and energy-hold applications.
