UBY1E472MHL

The UBY1E472MHL is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBY series, specified at 4700 µF and 25 V. It is a polarized can-style capacitor designed for high-temperature, high-ripple-current applications.

Built for demanding control electronics, this part targets automotive and industrial control circuits where elevated operating temperature, high ripple capability and long endurance are required. Key value propositions include high capacitance in a compact radial can, low ESR at high frequency, and AEC‑Q200 qualification for automotive use.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Temperature Range — Rated to operate from −40°C to 135°C, with endurance specified for 3000 hours at 135°C under DC bias plus rated ripple current.
• High Ripple Current Capability — Low-frequency ripple current of 2.439 A (120 Hz) and high-frequency ripple current of 2.87 A (100 kHz) to handle demanding power filtering and smoothing loads.
• Low ESR — Equivalent series resistance of 26 mΩ measured at 20°C / 100 kHz, supporting efficient energy transfer and reduced heat generation.
• Loss Tangent — tan δ (DF) of 0.2 measured at 20°C, 120 Hz for this part number, providing a measure of dielectric loss under test conditions.
• Polarized Radial Can Package — Radial lead mounting with φ16 × 25L size and 7.5 mm lead spacing (±0.5 mm), packaged in bulk / bag packing as supplied.
• Automotive-Grade Qualification — AEC‑Q200 rating indicated in the product data, suitable for automotive control circuit designs.
• Leakage Current — Specified leakage current of 3525 µA after 1 minute’s application of rated voltage at 20°C for this part configuration.

Typical Applications

• Automotive control modules — Voltage smoothing and energy buffering in control electronics that require high-temperature endurance and AEC‑Q200 qualification.
• Electric power steering systems — Filtering and decoupling in steering control assemblies where high ripple current handling and low ESR reduce thermal stress.
• Direct injection engine drive electronics — Bulk energy storage and decoupling for injector drivers and high-demand engine-control circuits operating at elevated temperatures.

Unique Advantages

• High capacitance in a compact radial can — 4700 µF in a φ16 × 25L package provides substantial energy storage where board area is constrained.
• Designed for high-temperature operation — Endurance rated for 3000 hours at 135°C supports applications exposed to elevated ambient and internal temperatures.
• High ripple current capability — Dual ripple current ratings (2.439 A @120 Hz, 2.87 A @100 kHz) enable reliable performance under both low- and high-frequency stress.
• Low ESR at high frequency — 26 mΩ at 100 kHz reduces I2R losses and helps control self-heating in power electronics.
• AEC‑Q200 qualified — Offers traceable automotive-grade reliability for control systems requiring industry qualification.
• Standard radial lead form factor — Simple through-hole mounting and familiar mechanical dimensions (7.5 mm lead spacing) streamline assembly into existing designs.
