UPS1V681MHD

The UPS1V681MHD is a miniature, low-impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose electronic applications. It is a radial-lead, can-style capacitor offering 680 µF capacitance at a 35 V rated voltage with RoHS compliance.

This part is specified for wide temperature operation from −55°C to +105°C and is rated for 3000 hours of endurance at 105°C, making it suitable for designs that require sustained performance under elevated temperature and ripple conditions.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 35 V with ±20% tolerance (120 Hz, 20°C).
• Low Impedance — Specified impedance of 75 mΩ to support low-voltage ripple and stable decoupling performance.
• High Ripple Handling — Rated ripple current of 887.5 mA at 120 Hz and 1.25 A at 10 kHz, suitable for handling switching ripple across common power-supply frequencies.
• Wide Temperature Range — Operating temperature from −55°C to +105°C to accommodate demanding thermal environments.
• Endurance — Lifetime specified as 3000 hours at 105°C under rated bias and ripple conditions.
• Package & Mounting — Radial lead, can-style package with 5 mm lead spacing for through-hole PCB layouts.
• Polarized Construction — Polarized aluminum electrolytic design for DC filtering and energy storage applications.
• Regulatory — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Filtering and smoothing of switching outputs where low impedance and rated ripple current reduce voltage ripple.
• General-Purpose Power Filtering — Bulk decoupling and bulk energy storage in general electronic equipment.
• DC Power Rail Stabilization — Local energy reservoir for rail hold-up and transient response in board-level power systems.

Unique Advantages

• Measured Low-Impedance Performance: The 75 mΩ impedance rating provides quantifiable reduction of AC ripple voltage in power paths.
• Documented Ripple Capability: Explicit ripple current ratings at 120 Hz (887.5 mA) and 10 kHz (1.25 A) let designers verify thermal and ripple handling against system conditions.
• Wide Operating Temperature: −55°C to +105°C operation and a 3000-hour endurance at 105°C support sustained performance in thermally challenging designs.
• Radial Can Form Factor: Through-hole radial lead packaging with 5 mm lead spacing simplifies PCB placement and mechanical retention for power assemblies.
• RoHS Compliance: Conforms to RoHS directives for use in assemblies requiring restricted substances compliance.
