UBW1H4R7MPD

The UBW1H4R7MPD is a radial lead aluminum electrolytic capacitor designed for high-temperature, long-life applications. It provides 4.7 µF capacitance at 50 V in a compact φ8 × 11.5 mm can suitable for through‑hole mounting.

Engineered for demanding environments, this AEC‑Q200 rated component combines a wide operating temperature range (–55°C to 135°C) and a 1000‑hour endurance at 135°C, delivering reliable filtering and decoupling where elevated temperature and longevity are required.

Key Features

• Capacitance and tolerance — 4.7 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, for predictable charge storage and decoupling performance.
• Rated voltage — 50 V DC rating for use in mid‑voltage power rails and supply circuits.
• High temperature capability — Specified operating range of –55°C to 135°C and endurance of 1000 hours at 135°C for sustained performance in hot environments.
• Low loss (tan δ) — tan δ = 0.10 (at 20°C, 120 Hz) to help minimize dissipation in AC or ripple conditions.
• Ripple current handling — Rated ripple current of 42.5 mA at 120 Hz and 85 mA at 10 kHz to support smoothing and decoupling under varying frequency conditions.
• Low leakage — Leakage current specified at 7.05 µA for minimal standby current and predictable bias drain.
• Compact radial can — φ8 × 11.5 mm package with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting for robust through‑hole assembly.
• AEC‑Q200 rating — Automotive‑grade qualification listed in the product specifications for reliability-focused designs.
• Packaging options — Supplied in bulk (no terminal forming) or bag packing to match assembly and handling preferences.

Typical Applications

• Automotive electronics — Suited for power filtering and decoupling in automotive modules and control units that require AEC‑Q200‑level reliability and high temperature endurance.
• Power supply smoothing — Use for bulk smoothing and ripple reduction on mid‑voltage DC rails where 50 V rating and rated ripple currents are needed.
• Industrial and harsh‑environment electronics — Applicable for sensor interfaces, actuator drivers, and control boards operating across –55°C to 135°C.

Unique Advantages

• High‑temperature endurance: 1000 hours at 135°C provides predictable lifetime behavior in elevated‑temperature applications.
• Automotive‑grade qualification: AEC‑Q200 listing supports designs that demand recognized reliability standards.
• Compact through‑hole form factor: φ8 can and 3.5 mm lead spacing deliver a small footprint with durable radial lead mounting for mechanical robustness.
• Balanced electrical performance: Combination of low tan δ, controlled impedance (1.15 Ω), and rated ripple currents supports stable filtering across frequency ranges.
• Low leakage current: 7.05 µA leakage improves standby characteristics and predictable bias behavior in low‑current circuits.
• Flexible packaging: Bulk or bag packing options simplify procurement and assembly workflows.
