UWJ1H2R2MCL1GB

The UWJ1H2R2MCL1GB is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 2.2 µF capacitance at a 50 V rating in a compact φ4 × 5.4 mm can-style SMD package with embossed carrier taping for automated placement.

Engineered for temperature-stable performance and reliability, this part supports -40°C to 85°C operation, AEC-Q200 qualification for automotive applications, and compatibility with 260°C peak reflow processes. Note: this product is listed as End of Life and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 2.2 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for predictable filtering and energy storage.
• Surface-Mount Chip Package — Chip-type radial can (SMD) in a compact φ4 × 5.4 mm footprint with recommended land size 4.3 × 4.3 mm, suitable for high-density PCBs and automated placement.
• High-Temperature Reflow Compatible — Rated for 260°C peak reflow (recommended condition: 260°C peak, 5 s), enabling standard SMT assembly flows.
• Automotive-Grade Reliability — AEC-Q200 compliant for automotive applications, with a rated load life of 2000 hours at 85°C.
• Low Leakage & Controlled Loss — Leakage current specified at 3 µA and a tangent of loss angle (tan δ) of 0.12 (max) at 20°C, 120 Hz for stable performance in low-current circuits.
• Ripple Current Capability — 13 mA at 120 Hz (low frequency) and 19.5 mA at 10 kHz (high frequency), supporting smoothing and decoupling in power stages.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.
• Carrier Taping — Embossed carrier taping provided for compatibility with automated pick-and-place equipment.

Typical Applications

• Automotive Power Conditioning — Smoothing and decoupling in automotive control modules where AEC-Q200 qualification is required.
• DC–DC Converter Output Filtering — Local energy storage and ripple attenuation for regulator outputs operating up to 50 V.
• Sensor and ECU Power Rails — Low leakage and controlled tan δ make it suitable for power stabilization in electronic control units and sensor electronics.

Unique Advantages

• Automotive-Ready Qualification: AEC-Q200 compliance supports use in vehicle electronics that require component-level reliability verification.
• Reflow-Compatible SMD Form Factor: 260°C peak reflow rating and embossed carrier tape enable straightforward integration into automated SMT lines.
• Compact, High-Voltage Option: 50 V rating in a small φ4 × 5.4 mm package provides higher voltage capability without a large footprint.
• Designed for Long Life at Elevated Temperature: 2000 h rated life at 85°C helps ensure sustained performance in thermal environments common to power electronics.
• Low Leakage and Defined Loss: 3 µA leakage and a 0.12 tan δ at 120 Hz offer stable behavior for low-current and precision power applications.
