UBW1J330MPD

The UBW1J330MPD is a radial-lead aluminum electrolytic capacitor designed for high-temperature, long-life applications. It provides 33 µF capacitance at a 63 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Engineered for robust performance up to +135°C and qualifying to AEC-Q200, this part targets demanding electronics where elevated operating temperature, reliable ripple handling and compact radial packaging are required.

Key Features

• Capacitance and Voltage — 33 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• High-temperature endurance — Rated for operation from −55°C to +135°C with a specified lifetime of 1000 hours at +135°C (φ8 size).
• Automotive-grade qualification — Designed to AEC-Q200 requirements for applications that require component-level automotive qualification.
• Low dissipation factor — tanδ = 0.1 (measured at 20°C, 120 Hz), supporting efficient filtering and decoupling.
• Ripple current capability — Handles 100.5 mA at 120 Hz (low frequency) and 150 mA at 10 kHz (high frequency), suitable for power filtering on switching supplies.
• Leakage and impedance — Specified leakage current of 62.37 µA and impedance of 1.5 Ω for predictable DC performance.
• Radial lead package — φ8 can with 3.5 mm lead spacing (±0.5 mm) supplied in bulk or bag packing for through-hole assembly.

Typical Applications

• Automotive electronics — Power rail decoupling and smoothing in modules that require components qualified to AEC-Q200 and rated for +135°C operation.
• Power supply filtering — Input/output smoothing and ripple suppression on DC‑DC converters and linear regulators, leveraging rated voltage, ripple current capacity and low tanδ.
• Motor control and power electronics — Local energy storage and transient suppression in compact, high-temperature environments where radial through-hole mounting is used.
• Industrial control — Filtering and hold-up in sensor interfaces, controller boards, and other systems exposed to elevated ambient temperatures.

Unique Advantages

• High-temperature reliability: Tested for 1000 hours at +135°C (φ8), delivering predictable capacitance retention and leakage behavior under elevated-temperature stress.
• AEC-Q200 qualified: Provides a verified qualification path for designs that require automotive-grade component selection.
• Compact radial form factor: φ8 × 11.5 mm can with tight lead spacing (3.5 mm) minimizes board area while enabling through-hole mounting and robust mechanical connection.
• Measured AC performance: Low tanδ (0.1 at 20°C, 120 Hz) and defined impedance (1.5 Ω) simplify decoupling and stability calculations for power designs.
• Documented ripple handling: Separate low- and high-frequency ripple current specifications (100.5 mA at 120 Hz, 150 mA at 10 kHz) let designers size components for real-world switching and line conditions.
• Production-ready packaging: Available in bulk (no terminal forming) or bag packing to support assembly and inventory workflows.
