UHE1A681MPD6

The UHE1A681MPD6 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHE series. It provides 680 µF nominal capacitance at a 10 V rating in a compact, miniature can-style package intended for general-purpose electronic applications.

Designed for low impedance and extended high-temperature endurance, this part targets designs that require bulk capacitance, ripple handling and long life in a small radial package.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance rated at 10 V with ±20% tolerance.
• Low Impedance — Specified impedance of 320 mΩ to support lower ripple and improved transient performance.
• High Ripple Handling — Rated ripple current of 865 mA at 10 kHz and 648.8 mA at 120 Hz, with frequency coefficients per the UHE series data.
• Long Endurance — Rated for 6000 hours at 105°C under the specified endurance conditions for 6.3–10 V, φD = 8, 10 case sizes.
• Temperature Range — Operates from −40°C to +105°C.
• Radial Can Package — φ10 × 12.5L can size with 5 mm lead spacing and 0.5 mm lead diameter; supplied bulk (no terminal forming) in bag packing for production handling.
• Leakage Current — Typical leakage current specified at 68 µA for this part.
• RoHS Compliance — Compliant with RoHS requirements.

Typical Applications

• General-purpose power circuitry — Bulk energy storage and smoothing in power supplies where a compact, high-capacitance radial electrolytic is required.
• Decoupling and filtering — Local decoupling for boards and modules where low impedance and rated ripple current improve stability under dynamic loads.
• Embedded and industrial electronics — Long-life installations operating up to 105°C that benefit from extended endurance and compact footprint.

Unique Advantages

• Compact, high-capacitance solution: 680 µF in a φ10 × 12.5L can provides substantial capacitance while minimizing PCB area.
• Low impedance for improved ripple performance: 320 mΩ impedance and high rated ripple current (865 mA at 10 kHz) help reduce voltage modulation under AC stress.
• High-temperature endurance: Rated 6000 hours at 105°C for 6.3–10 V, offering predictable long-term performance in elevated-temperature environments.
• Radial-lead convenience: 5 mm lead spacing and 0.5 mm lead diameter simplify through-hole mounting and automated insertion workflows when terminal forming is not required.
• Regulatory compliance: RoHS-compliant construction supports restricted-substance requirements for commercial and industrial products.
