UPM1H4R7MDD

The UPM1H4R7MDD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering 4.7 µF capacitance with a 50 V rated voltage. It combines compact through‑hole packaging (φ5 × 11 mm) and a wide operating temperature range for demanding environments.

Designed for applications requiring automotive‑grade qualification and reliable performance, this part provides a defined endurance rating and measured electrical characteristics suitable for engineers specifying robust, small‑form through‑hole capacitors.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) for predictable decoupling and energy storage behavior.
• Rated Voltage — 50 V nominal voltage rating suitable for mid‑voltage circuits requiring stable electrolytic capacitance.
• Electrical Loss & Leakage — Specified tanδ of 0.10 (measured at 20°C, 120 Hz) and leakage current of 7.05 µA, enabling predictable AC loss and DC leakage performance.
• Ripple Current Ratings — Low‑frequency ripple current 20 mA (120 Hz) and high‑frequency ripple current 40 mA (200 kHz) for defined ripple handling across frequencies.
• Reliability & Endurance — Rated endurance of 2000 hours at 105°C, providing a quantified life expectation for thermal stress conditions.
• Mechanical & Mounting — Radial lead, can package with 2.0 mm lead spacing (±0.5 mm) and compact dimensions φ5 × 11 mm for through‑hole assembly and space‑constrained boards.
• Environmental & Qualification — RoHS compliant and AEC‑Q200 listed in the product data, aligning with qualification and environmental requirements for regulated applications.
• Packaging — Supplied in bulk (no terminal forming) / bag packing to support volume handling and automated or manual assembly workflows.

Typical Applications

• Automotive electronics — Specified for automotive use with AEC‑Q200 listing and an operating range of −55°C to 105°C, suitable for in‑vehicle modules that require qualified components.
• Through‑hole PCB assemblies — Compact radial can (φ5 × 11 mm) and 2 mm lead spacing make it suitable for space‑sensitive through‑hole designs and mixed‑technology boards.
• Production stocking and assembly — Bulk/bag packing supports volume BOMs and stocking strategies for contract manufacturers and OEM production lines.

Unique Advantages

• AEC‑Q200 listing: Provides the documentation and qualification posture expected for automotive and other high‑reliability programs.
• Compact radial footprint: φ5 × 11 mm package and 2 mm lead spacing reduce board area while retaining through‑hole robustness.
• Defined thermal endurance: 2000 hours at 105°C gives a clear, testable lifetime metric for thermal stress planning.
• Measured loss and leakage specs: tanδ = 0.10 and leakage = 7.05 µA allow predictable power dissipation and standby current budgeting.
• Dual‑frequency ripple specification: Rated ripple currents for both low (120 Hz) and high (200 kHz) frequencies support designers addressing a range of switching and AC conditions.
• RoHS compliant: Meets common environmental restrictions for global product deployment and supply chain requirements.
