UHD1A681MPD6

The UHD1A681MPD6 is a Nichicon UHD series radial-lead aluminum electrolytic capacitor offering 680 µF capacitance at a 10 V rating. Designed for general-purpose electronic designs, this part emphasizes high ripple handling and low impedance in a compact φ10 × 12.5 mm can.

With a wide operating temperature range of −40°C to 105°C and a rated endurance of 4000 hours at 105°C, the UHD1A681MPD6 delivers measurable performance for applications that require reliable ripple current capability and stable operation over time.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 10 V and capacitance tolerance of -20%~20%.
• Low Loss (tan δ) — tanδ = 0.19 measured at 20°C, 120 Hz, 10 V, supporting efficient AC performance and reduced dissipation.
• High Ripple Current Capability — Low-frequency ripple current: 772.5 mA at 120 Hz; high-frequency ripple current: 1.03 A at 100 kHz, enabling effective smoothing and filtering at multiple frequencies.
• Leakage Current — Typical leakage current of 68 µA (measured per product data), supporting predictable bias performance.
• Endurance & Temperature Range — Rated life of 4000 hours at 105°C and an operating temperature range from −40°C to 105°C for extended reliability under elevated-temperature conditions.
• Compact Radial Package — φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole PCB designs.
• RoHS Compliant & Production Ready — RoHS status: Compliant; packaging options include Bulk (no terminal forming) and Bag packing; status: Mass Production.
• Series-level Characteristics — Part of the UHD series, which is specified for lower impedance at high frequency, smaller case sizes, and high ripple current capability.

Typical Applications

• General-purpose power filtering — Suited to smoothing and decoupling tasks where high ripple current capacity and low impedance at higher frequencies are required.
• High-frequency ripple handling — The combination of low tanδ and measured high-frequency ripple current (1.03 A at 100 kHz) makes it appropriate for designs with significant HF content.
• Through-hole PCB designs — Radial-lead package and 5 mm lead spacing provide a compact solution for through-hole power boards and assemblies.

Unique Advantages

• Measurable ripple performance — Specified LF ripple current of 772.5 mA (120 Hz) and HF ripple current of 1.03 A (100 kHz) let designers quantify thermal and ripple budgets.
• Predictable dissipation — tanδ = 0.19 at the specified test condition provides a clear indicator of loss behavior for thermal planning.
• Compact footprint — φ10 × 12.5 mm can with radial leads reduces board space compared with larger cans while retaining high ripple capability.
• Extended high-temperature life — 4000 hours at 105°C supports longevity in thermally demanding environments.
• Controlled leakage — Leakage current specified at 68 µA aids in predictable bias and standby current calculations.
• Regulatory readiness — RoHS compliance facilitates use in products targeting regulated markets.
