UHD1A392MHD

The UHD1A392MHD is a radial-lead aluminum electrolytic capacitor offering 3.9 mF capacitance at a 10 V rating in a compact φ12.5 × 30.5 mm can. It is part of the UHD series designed for lower impedance at high frequency and higher ripple-current capability.

Engineered for general-purpose electronic assemblies, the device combines high capacitance density, defined ripple-current performance at both low and high frequencies, and long-term endurance for robust board-level energy storage and decoupling needs.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a rated voltage of 10 V and capacitance tolerance of ±20%.
• Ripple Current Performance — Supports 2.632 A at 120 Hz (low frequency) and 3.29 A at 100 kHz (high frequency), enabling reliable operation under AC ripple conditions.
• Low Impedance at High Frequency — Series-level characteristic of reduced impedance in the high frequency range to improve performance in circuits with switching or fast ripple components.
• Leakage Current — Specified leakage current of 390 µA (after 2 minutes at 20°C), providing predictable standby and bias behavior.
• Endurance & Temperature Range — Rated for operation from −40°C to 105°C with an endurance of 5000 hours at 105°C.
• Package & Mounting — Radial lead can with φ12.5 mm diameter, length 30.5 mm, 5.0 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronic assemblies — Provides bulk capacitance for a wide range of general-purpose circuits requiring a polarized radial electrolytic capacitor.
• High-ripple power stages — Suited for circuits where substantial ripple currents are present, with 2.632 A at 120 Hz and 3.29 A at 100 kHz rating.
• High-temperature deployments — Useful in designs that must operate across −40°C to 105°C and require long-term endurance (5000 h at 105°C).
• Space-constrained board-level designs — Delivers high capacitance in a compact φ12.5 × 30.5 mm package with 5 mm lead spacing for through-hole mounting.

Unique Advantages

• High ripple-handling capability: Explicit ripple-current ratings at both low and high frequencies let designers specify the UHD1A392MHD with confidence in ripple-intensive circuits.
• Improved high-frequency performance: The UHD series’ lower impedance at high frequency supports better decoupling and transient response where fast switching occurs.
• Compact high-capacitance package: 3.9 mF in a φ12.5 × 30.5 mm can reduces board footprint compared to larger radial options while maintaining bulk capacitance.
• Long-term thermal endurance: 5000 hours at 105°C provides predictable aging characteristics for sustained high-temperature operation.
• Predictable leakage behavior: A specified leakage current (390 µA) enables accurate bias and standby current budgeting in designs.
• RoHS compliant and production-ready: Mass-production status and RoHS compliance support procurement and regulatory needs.
