UVY1E103MHD

The UVY1E103MHD is a radial-lead aluminum electrolytic capacitor offering 10,000 µF capacitance at a 25 V rated voltage. Designed for general-purpose electronic circuits, it delivers large bulk capacitance in a compact φ18 × 40 mm can with radial lead mounting.

Key value comes from its combination of high capacitance, elevated ripple-current capability at both low and high frequencies, wide operating temperature span, and a 2000-hour endurance rating at 105°C—making it suitable for designs that require stable bulk energy storage under thermal stress.

Key Features

• Capacitance & Tolerance — 10,000 µF with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 25 V DC rating for common low-voltage power rails.
• Ripple Current — Low-frequency ripple current: 2000 mA at 120 Hz; high-frequency ripple current: 2300 mA at 10 kHz, supporting both mains-frequency and higher-frequency filtering needs.
• Dissipation Factor (tan δ) — 0.34 measured at 20°C, 120 Hz, 25 V, enabling evaluation of AC loss in design.
• Leakage Current — 7500 µA initial leakage for design budgeting and startup considerations.
• Temperature Range & Endurance — Rated for -55°C to +105°C with a 2000-hour endurance at 105°C.
• Package & Mounting — Radial lead, aluminum can package; physical size φ18 × 40 mm with 7.5 mm lead spacing (±0.5 mm); supplied bulk or bag packed.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power supplies and DC filtering — Bulk energy storage and smoothing on 25 V rails, leveraging 10,000 µF capacitance and 2 A ripple capability at 120 Hz.
• Industrial control equipment — Operates across -55°C to +105°C and meets a 2000-hour endurance requirement for elevated-temperature environments.
• Consumer and commercial electronics — General-purpose decoupling and hold-up applications where compact high-capacitance solution is needed.
• High-frequency power circuits — Supports higher-frequency ripple currents (2.3 A at 10 kHz) for switching regulator and converter applications.

Unique Advantages

• High bulk capacitance in a compact can: 10,000 µF packaged in a φ18 × 40 mm radial can conserves board area while providing large energy storage.
• Dual-frequency ripple capability: Rated ripple current figures at both 120 Hz and 10 kHz allow straightforward selection for mains-frequency and switching applications.
• Wide operating temperature span: -55°C to +105°C supports use in systems exposed to broad thermal conditions.
• Long endurance at elevated temperature: 2000-hour rating at 105°C helps ensure sustained performance in high-temperature installations.
• Design predictability: Specified tan δ (0.34) and leakage current (7500 µA) let engineers budget losses and startup currents precisely.
• Regulatory compliance: RoHS compliant for use in lead-restricted products.
