UHE1A332MHD

The UHE1A332MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UHE series, offering 3300 µF capacitance at a 10 V rating in a compact can-style package. It is designed for general-purpose electronic applications that require high capacitance, low impedance and reliable long-term operation.

Key value comes from a combination of low impedance (89 mΩ), substantial ripple-current capability at both low and high frequencies, and an extended life rating, all in a small φ12.5 × 25 mm radial package with 5 mm lead spacing.

Key Features

• Capacitance & Voltage – 3300 µF (3.3 mF) rated at 10 V with a tolerance of ±20%.
• Low Impedance – 89 mΩ impedance for improved filtering performance and reduced voltage drop under load.
• High Ripple Current Handling – 1.784 A at 120 Hz (low frequency) and 2.23 A at 10 kHz (high frequency) to support dynamic loads and switching environments.
• Long Life & Temperature Range – Endurance rated to 8000 hours at 105 °C and an operating temperature range of −40 °C to 105 °C.
• Leakage & Dissipation – Leakage current of 330 µA and dissipation factor (tanδ) of 0.23 measured at 20 °C, 120 Hz, 10 V for predictable loss characteristics.
• Package & Mounting – Radial lead, polarized aluminum can; physical size φ12.5 × 25 mm with 5.0 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing. Status: Mass Production.
• Compliance – RoHS compliant.

Typical Applications

• Power supply filtering – Bulk smoothing and decoupling on 10 V rails where high capacitance and low impedance improve transient response.
• DC–DC converter output filtering – Output energy storage and ripple reduction for general-purpose converters operating within the capacitor's voltage and temperature limits.
• Embedded and industrial electronics – Bulk decoupling in control modules and embedded systems that require reliable operation from −40 °C to 105 °C.

Unique Advantages

• High ripple capability: Dual-spec ripple ratings at 120 Hz and 10 kHz (1.784 A and 2.23 A respectively) reduce thermal stress in applications with both low- and high-frequency content.
• Compact high-capacitance option: 3300 µF in a φ12.5 × 25 mm can supports space-constrained through-hole designs without sacrificing capacitance.
• Extended high-temperature endurance: 8000 hours at 105 °C supports long-term operation in hot environments, improving product longevity.
• Predictable electrical behavior: Specified tanδ and leakage current values measured at defined conditions provide designers with predictable loss and leakage performance for reliable design margining.
• Ready for production: Mass-production status and multiple packing options (bulk/bag) simplify procurement and assembly planning.
