UHV1E680MDD

The UHV1E680MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHV high-reliability series. It delivers 68 µF capacitance at a 25 V rating in a compact φ5 × 11 mm can suitable for space-constrained designs.

Designed for general-purpose applications, the UHV series emphasizes lower impedance at high frequency and elevated ripple-current capability, making this part appropriate where compact size, high-frequency performance, and reliability across –40°C to 105°C are required.

Key Features

• Electrical Characteristics — 68 µF nominal capacitance with tolerance of −20% to +20% and a rated voltage of 25 V.
• Loss Angle (tan δ) — tanδ = 0.13 measured at 20°C, 120 Hz, providing a quantified dissipation factor for circuit design.
• Low Leakage & Polarization — Polarized aluminum electrolytic construction with leakage current specified at 17 µA.
• High-Frequency Performance & Ripple Handling — Low-frequency ripple current 144 mA (120 Hz) and high-frequency ripple current 360 mA (100 kHz) for improved filtering and decoupling at multiple frequencies.
• Reliability and Endurance — Rated life of 5000 hours at 105°C for long-term operation in elevated-temperature environments.
• Compact Radial Package — Radial lead mounting in a φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for manual or automated assembly.
• Operating Temperature Range — Specified for −40°C to +105°C to cover a wide range of ambient conditions.

Typical Applications

• Compact Power Supplies — Local smoothing and filtering where a 25 V, 68 µF radial capacitor is required and board space is limited.
• Noise Suppression and Decoupling — High-frequency low-impedance behavior and specified ripple currents support decoupling in mixed-signal and power electronics.
• Portable and Instrumentation Electronics — Small can size and broad temperature rating make it suitable for compact instruments and portable devices requiring reliable capacitance.

Unique Advantages

• Compact footprint: φ5 × 11 mm case size provides 68 µF capacitance in a small package for space-constrained PCBs.
• Defined high-frequency performance: Measured tanδ (0.13 at 20°C/120 Hz) and specified ripple currents at 120 Hz and 100 kHz give clear design parameters for filter and decoupling networks.
• Wide operating temperature: −40°C to 105°C rating supports deployment across varied environmental conditions without derating the component choice.
• Long endurance at elevated temperature: 5000-hour life at 105°C supports reliable operation in applications with sustained thermal stress.
• Polarized aluminum electrolytic benefits: Established technology with low leakage current (17 µA) suitable for many general-purpose power applications.
• Flexible packaging: Available in bulk or bag packing to suit production or prototype needs.
