UCD1H151MNL1GS

The UCD1H151MNL1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount can designed for high-density PCB assemblies. It delivers 150 µF at 50 V with a temperature capability up to 105°C and is supplied in embossed carrier tape for automated mounting.

Targeted for demanding power applications, this part combines high ripple-current handling and long endurance (5000 hours at 105°C) with AEC-Q200 qualification and RoHS compliance for use in automotive and industrial systems.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance rated at 50 V with tolerance −20% to 20% for predictable bulk energy storage and decoupling.
• Low-impedance, chip-type design — Chip-type construction optimized for surface-mount use on high-density PC boards to minimize series impedance.
• Ripple current performance — Handles 350 mA at 120 Hz (low frequency) and 700 mA at 10 kHz (high frequency), supporting both bulk and high-frequency filtering.
• Loss and leakage — Tangent of loss angle (tan δ) of 0.10 at 20°C/120 Hz and specified leakage current of 75 µA for controlled dissipation and low standby draw.
• High-temperature endurance — Rated for 5000 hours at 105°C, meeting endurance requirements for extended operation in elevated ambient conditions.
• Robust temperature range — Operates from −55°C to +105°C to cover a wide set of environmental conditions.
• Surface-mount package — φ10 × 10L can construction, radial can SMD package, supplied in embossed carrier tape and compatible with automated placement; recommended land size L: 1.03 × W: 1.03 cm.
• Automotive-grade qualification & compliance — AEC‑Q200 qualified and RoHS compliant for regulated applications.

Typical Applications

• Automotive power rails — Bulk and decoupling for in-vehicle electronics where AEC‑Q200 qualification and extended temperature/long-life endurance are required.
• DC–DC converters — Input/output filtering and energy storage for converters benefiting from high ripple-current capability at both low and high frequencies.
• Industrial control systems — Power smoothing and transient suppression in controllers and power modules operating across −55°C to +105°C.
• High-density PCB assemblies — Surface-mount can design and embossed carrier tape packaging for automated, high-volume assembly on compact boards.

Unique Advantages

• AEC‑Q200 qualification: Provides a credential for automotive and other regulated applications that require recognized component-level reliability.
• Long high-temperature life: 5000 hours at 105°C supports extended field service life in elevated-heat environments.
• Balanced ripple performance: Rated ripple currents of 350 mA (120 Hz) and 700 mA (10 kHz) enable the same part to address both bulk smoothing and high-frequency filtering requirements.
• Low dissipation and controlled leakage: tan δ = 0.10 (20°C, 120 Hz) and 75 µA leakage give predictable thermal and standby characteristics for power-sensitive designs.
• Surface-mount, tape-ready packaging: φ10 can in embossed carrier tape simplifies automated placement on high-density assemblies and reduces BOM complexity.
• Wide operating temperature: −55°C to +105°C supports deployment across broad environmental and industrial temperature ranges.
