UHD1E102MHD

The UHD1E102MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHD series. It is a radial-lead, polarized capacitor with a rated capacitance of 1000 µF and a rated voltage of 25 V, optimized for general-purpose electronic designs requiring compact size and elevated ripple handling.

Built for extended operation, the UHD1E102MHD supports continuous use across a –40°C to +105°C temperature range and a rated endurance of 5000 hours at 105°C, providing stable capacitance and controlled dissipation for demanding board-level power applications.

Key Features

• Electrical Performance: 1000 µF capacitance at 25 V with a tolerance of −20% to +20%, and a dissipation factor (tan δ) of 0.14 measured at 20°C, 120 Hz.
• High Ripple Capability: Low-frequency ripple current of 1.77 A (120 Hz) and high-frequency ripple current of 2.36 A (100 kHz), supporting applications with significant AC stress on DC rails.
• Low Leakage: Specified leakage current of 250 µA (typical measurement condition indicated in product data), enabling reliable storage of charge with minimal loss.
• Extended Endurance: Rated for 5000 hours at 105°C under DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage after the endurance test.
• Compact Radial Can Package: Case size φ12.5 × 20 mm (diameter × length) with radial leads and 5 mm lead spacing (±0.5 mm), suitable for through-hole mounting where a small footprint is required.
• RoHS Compliant & Packaging Options: RoHS-compliant construction and available in Bulk (no terminal forming) or Bag packing for flexible procurement and assembly workflows.

Typical Applications

• General-purpose power supplies: Compact power rails that require bulk capacitance and defined ripple-handling capability up to 2.36 A at high frequency.
• PCB-level energy storage: Through-hole designs needing 1000 µF of polarized capacitance in a φ12.5 × 20 mm footprint for smoothing and transient support.
• Industrial and consumer electronics (general-purpose): Designs operating across −40°C to +105°C where long-term endurance (5000 h at 105°C) and controlled leakage are important.

Unique Advantages

• High ripple tolerance: Clear ripple current ratings at both low and high frequencies (1.77 A at 120 Hz; 2.36 A at 100 kHz) align the part to applications with mixed-frequency stress.
• Compact, high-capacitance package: 1000 µF in a φ12.5 × 20 mm can reduces board area compared with larger-diameter alternatives while maintaining required capacitance.
• Long-term thermal stability: Endurance characterized to 5000 hours at 105°C provides predictable aging behavior for thermal and continuously stressed environments.
• Measured dissipation and leakage: Specified tan δ (0.14 at 20°C, 120 Hz) and leakage current figures allow engineers to predict loss and quiescent current for power-budget calculations.
• Through-hole mounting convenience: Radial lead format with 5 mm lead spacing simplifies placement and soldering for legacy and serviceable designs.
